Glossary of Crude Oil and Natural Gas Terms

The terms defined in this section may be used throughout this report:
“Bbl” One stock tank barrel, of 42 U.S. gallons liquid volume, used herein in reference to crude oil, condensate or natural gas liquids.
“Boe” Barrels of crude oil equivalent, with six thousand cubic feet of natural gas being equivalent to one barrel of crude oil based on the average equivalent energy content of the two commodities.
“Btu” British thermal unit, which represents the amount of energy needed to heat one pound of water by one degree Fahrenheit and can be used to describe the energy content of fuels.
“completion” The process of treating a drilled well followed by the installation of permanent equipment for the production of crude oil and/or natural gas.
“DD&A” Depreciation, depletion, amortization and accretion.
“developed acreage” The number of acres allocated or assignable to productive wells or wells capable of production.
“development well” A well drilled within the proved area of a crude oil or natural gas reservoir to the depth of a stratigraphic horizon known to be productive.
“dry hole” Exploratory or development well that does not produce crude oil and/or natural gas in economically producible quantities.
“enhanced recovery” The recovery of crude oil and natural gas through the injection of liquids or gases into the reservoir, supplementing its natural energy. Enhanced recovery methods are sometimes applied when production slows due to depletion of the natural pressure.
“exploratory well” A well drilled to find crude oil or natural gas in an unproved area, to find a new reservoir in an existing field previously found to be productive of crude oil or natural gas in another reservoir, or to extend a known reservoir beyond the proved area.
“field” An area consisting of a single reservoir or multiple reservoirs all grouped on, or related to, the same individual geological structural feature or stratigraphic condition. The field name refers to the surface area, although it may refer to both the surface and the underground productive formations.
“formation” A layer of rock which has distinct characteristics that differs from nearby rock.
"gross acres" or "gross wells" Refers to the total acres or wells in which a working interest is owned.
“horizontal drilling” A drilling technique used in certain formations where a well is drilled vertically to a certain depth and then drilled horizontally within a specified interval.
“MBbl” One thousand barrels of crude oil, condensate or natural gas liquids.
“MBoe” One thousand Boe.
“Mcf” One thousand cubic feet of natural gas.
“MMBoe” One million Boe.
“MMBtu” One million British thermal units.
“MMcf” One million cubic feet of natural gas.
net acres” or "net wells" Refers to the sum of the fractional working interests owned in gross acres or gross wells.
“NYMEX” The New York Mercantile Exchange.
“play” A portion of the exploration and production cycle following the identification by geologists and geophysicists of areas with potential crude oil and natural gas reserves.

i



“productive well” A well found to be capable of producing hydrocarbons in sufficient quantities such that proceeds from the sale of the production exceed production expenses and taxes.
“prospect” A potential geological feature or formation which geologists and geophysicists believe may contain hydrocarbons. A prospect can be in various stages of evaluation, ranging from a prospect that has been fully evaluated and is ready to drill to a prospect that will require substantial additional seismic data processing and interpretation.
“proved reserves” The quantities of crude oil and natural gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs and under existing economic conditions, operating methods, and government regulations prior to the time at which contracts providing the right to operate expire, unless evidence indicates renewal is reasonably certain.
“reservoir” A porous and permeable underground formation containing a natural accumulation of producible crude oil and/or natural gas that is confined by impermeable rock or water barriers and is separate from other reservoirs.
“royalty interest” Refers to the ownership of a percentage of the resources or revenues produced from a crude oil or natural gas property. A royalty interest owner does not bear exploration, development, or operating expenses associated with drilling and producing a crude oil or natural gas property.
“SCOOP” Refers to the South Central Oklahoma Oil Province, a term used to describe properties located in the Anadarko basin of Oklahoma in which we operate. Our SCOOP acreage extends across portions of Garvin, Grady, Stephens, Carter, McClain and Love Countiescounties of Oklahoma and has the potential to contain hydrocarbons from a variety of conventional and unconventional reservoirs overlying and underlying the Woodford formation.
"STACK" Refers to Sooner Trend Anadarko Canadian Kingfisher, a term used to describe a resource play located in the Anadarko Basin of Oklahoma characterized by stacked geologic formations with major targets in the Meramec, Osage and Osage formations overlying the Woodford formation.formations. A significant portion of our STACK acreage is located in over-pressured portions of Blaine, Dewey and Custer Countiescounties of Oklahoma.
“undeveloped acreage” Lease acreage on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of crude oil and/or natural gas.
“unit” The joining of all or substantially all interests in a reservoir or field, rather than a single tract, to provide for development and operation without regard to separate property interests. Also, the area covered by a unitization agreement.
“working interest” The right granted to the lessee of a property to explore for and to produce and own crude oil, natural gas, or other minerals. The working interest owners bear the exploration, development, and operating costs on either a cash, penalty, or carried basis.

Cautionary Statement for the Purpose of the “Safe Harbor” Provisions of the Private Securities Litigation Reform Act of 1995
This report and information incorporated by reference in this report include “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements other than statements of historical fact, including, but not limited to, forecasts or expectations regarding the Company's business and statements or information concerning the Company’s future operations, performance, financial condition, production and reserves, schedules, plans, timing of development, rates of return, budgets, costs, business strategy, objectives, and cash flows, included in this report are forward-looking statements. The words “could,” “may,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project,” “budget,” “plan,” “continue,” “potential,” “guidance,” “strategy” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words.
Forward-looking statements may include, but are not limited to, statements about:
our strategy;
our business and financial plans;
our future operations;
our crude oil and natural gas reserves and related development plans;
technology;
future crude oil, natural gas liquids, and natural gas prices and differentials;
the timing and amount of future production of crude oil and natural gas and flaring activities;
the amount, nature and timing of capital expenditures;
estimated revenues, expenses and results of operations;
drilling and completing of wells;

the ability and willingness of current or potential lenders, hedging contract counterparties, customers, and working interest owners to fulfill their obligations to us or to enter into transactions with us in the future on terms that are acceptable to us.
Forward-looking statements are based on the Company’s current expectations and assumptions about future events and currently available information as to the outcome and timing of future events. Although the Company believes these assumptions and expectations are reasonable, they are inherently subject to numerous business, economic, competitive, regulatory and other risks and uncertainties, most of which are difficult to predict and many of which are beyond the Company's control. No assurance can be given that such expectations will be correct or achieved or that the assumptions are accurate or will not change over time. The risks and uncertainties that may affect the operations, performance and results of the business and forward-looking statements include, but are not limited to, those risk factors and other cautionary statements described under Part II, Item 1A. Risk Factors and elsewhere in this report, if any, our Annual Report on Form 10-K for the year ended December 31, 2015,2016, registration statements we file from time to time with the Securities and Exchange Commission, and other announcements we make from time to time.
Readers are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date on which such statement is made. Should one or more of the risks or uncertainties described in this report or our Annual Report on Form 10-K occur, or should underlying assumptions prove incorrect, the Company's actual results and plans could differ materially from those expressed in any forward-looking statements. All forward-looking statements are expressly qualified in their entirety by this cautionary statement.
Except as expressly stated above or otherwise required by applicable law, the Company undertakes no obligation to publicly correct or update any forward-looking statement whether as a result of new information, future events or circumstances after the date of this report, or otherwise.

Continental Resources, Inc. and Subsidiaries
Notes to Unaudited Condensed Consolidated Financial Statements
Note 1. Organization and Nature of Business
Continental Resources, Inc. (the “Company”) was originally formed in 1967 and is incorporated under the laws of the State of Oklahoma. The Company's principal business is crude oil and natural gas exploration, development and production with properties primarily located in the North, South, and East regions of the United States. The North region consists of properties north of Kansas and west of the Mississippi River and includes North Dakota Bakken, Montana Bakken and the Red River units. The South region includes all properties south of KansasNebraska and west of the Mississippi River including various plays in the SCOOP (South Central Oklahoma Oil Province), STACK (Sooner Trend Anadarko Canadian Kingfisher), Northwest Cana, and Arkoma Woodford areas of Oklahoma. The East region is primarily comprised of undeveloped leasehold acreage east of the Mississippi River with no currentsignificant drilling or production operations.
A substantial portion of the Company’s operations are concentratedlocated in the North region, with that region comprising approximately 64%57% of the Company’s crude oil and natural gas production and approximately 73%66% of its crude oil and natural gas revenues for the six months ended June 30, 2016.2017. The Company's principal producing properties in the North region are located in the Bakken field of North Dakota and Montana. In recent years, the Company has significantly expanded its activityoperations in the South region with its discovery of the SCOOP play and its increased activity in the Northwest CanaSCOOP and STACK plays. The South region comprised approximately 36%43% of the Company's crude oil and natural gas production and approximately 27%34% of its crude oil and natural gas revenues for the six months ended June 30, 2016.2017.
The Company has focused its operations on the exploration and development of crude oil since the 1980s. For the six months ended June 30, 2016,2017, crude oil accounted for approximately 62%56% of the Company’s total production and approximately 87%76% of its crude oil and natural gas revenues.    
Note 2. Basis of Presentation and Significant Accounting Policies
Basis of presentation
The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are 100% owned, after all significant intercompany accounts and transactions have been eliminated upon consolidation.
This report has been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) applicable to interim financial information. Because this is an interim period filing presented using a condensed format, it does not include all disclosures required by accounting principles generally accepted in the United States (“U.S. GAAP”), although the Company believes the disclosures are adequate to make the information not misleading. You should read this Quarterly Report on Form 10-Q ("Form 10-Q") together with the Company’s Annual Report on Form 10-K for the year ended December 31, 20152016 (“20152016 Form 10-K”), which includes a summary of the Company’s significant accounting policies and other disclosures.
The condensed consolidated financial statements as of June 30, 20162017 and for the three and six month periods ended June 30, 20162017 and 20152016 are unaudited. The condensed consolidated balance sheet as of December 31, 20152016 was derived from the audited balance sheet included in the 20152016 Form 10-K. The Company has evaluated events or transactions through the date this report on Form 10-Q was filed with the SEC in conjunction with its preparation of these condensed consolidated financial statements.
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure and estimation of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results may differ from those estimates. The most significant of the estimates and assumptions that affect reported results are the estimates of the Company’s crude oil and natural gas reserves, which are used to compute depreciation, depletion, amortization and impairment of proved crude oil and natural gas properties. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation in accordance with U.S. GAAP have been included in these unaudited interim condensed consolidated financial statements. The results of operations for any interim period are not necessarily indicative of the results of operations that may be expected for any other interim period or for an entire year.
Earnings per share
Basic and diluted net income (loss)loss per share is computed by dividing net income (loss)loss by the weighted-average number of shares outstanding for the period. In periods where the Company has net income, diluted earnings per share reflects

(1)DuringFor the three and six months ended June 30, 2016 and the six months ended June 30, 2015,2017, the Company had a net loss and therefore the potential dilutive effect of approximately 1,940,700, 1,486,200,1,933,200 and 1,472,3002,546,200 weighted average non-vested restricted shares, respectively, were not included in the calculation of diluted net loss per share because to do so would have been anti-dilutive to the computations. The Company also had net losses for the three and six months ended June 30, 2016, and therefore approximately 1,940,700 and 1,486,200 weighted average non-vested restricted shares, respectively, were not included in the calculation of diluted net loss per share for those periods.
Inventories
Inventory is comprised of crude oil held in storage or as line fill in pipelines and tubular goods and equipment to be used in the Company's exploration and development activities. Crude oil inventories are valued at the lower of cost or market primarily using the first-in, first-out inventory method. Tubular goods and equipment are valued at the lower of cost or market, with cost determined primarily using a weighted average cost method applied to specific classes of inventory items.
The components of inventory as of June 30, 20162017 and December 31, 20152016 consisted of the following:

Income taxes
Income taxes are accounted for using the liability method under which deferred income taxes are recognized for the future tax effectsAdoption of temporary differences between financial statement carrying amounts and the tax basis of existing assets and liabilities using the enacted statutory tax rates in effect at period-end. The effect on deferred taxes for a change in tax rates is recognized in income in the period that includes the enactment date. The Company’s policy is to recognize penalties and interest related to unrecognized tax benefits, if any, in income tax expense. A valuation allowance for deferred tax assets is recorded when it is more likely than not that the benefit from the deferred tax asset will not be realized. The Company recorded valuation allowances of $0.2 million and $0.3 million for the three and six months ended June 30, 2016, respectively, and $1.3 million and $12.4 million for the three and six months ended June 30, 2015, respectively, against deferred tax assets associated with operating loss carryforwards generated by its Canadian subsidiary for which the Company does not expect to realize a benefit.
Newnew accounting pronouncements not yet adopted
Stock-based compensation – In FebruaryMarch 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2016-02,("ASU") 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which changes how companies account for certain aspects of share-based payment awards, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Company adopted the new standard on January 1, 2017 as required. The impact of adoption is described below.
ASU 2016-09 removes the requirement to delay recognition of an excess tax benefit until it reduces current taxes payable. An excess tax benefit (tax deficiency) arises when stock-based compensation expense recognized in an entity’s tax return exceeds (is less than) the expense recognized in an entity’s financial statements. Under the new standard, effective January 1, 2017 excess tax benefits are recorded when they arise. This change was required to be applied on a modified retrospective basis by recording a cumulative effect adjustment to opening retained earnings upon adoption to account for previously unrecognized excess tax benefits. The Company's cumulative effect adjustment recorded under the new standard resulted in a $5.2 million increase in retained earnings and corresponding decrease in deferred income tax liabilities at January 1, 2017.
Additionally, under ASU 2016-09 companies no longer record excess tax benefits and deficiencies in additional paid-in capital. Instead, excess tax benefits and deficiencies are recognized as income tax benefit or expense in the income statement, effective January 1, 2017 on a prospective basis. This is expected to result in increased volatility in income tax expense/benefit and corresponding variations in the relationship between income tax expense/benefit and pre-tax income/loss from period to period. The Company recognized $0.5 million ($0.00 per share) and $3.8 million ($0.01 per share) of tax deficiencies from stock-based compensation as income tax expense for the three and six months ended June 30, 2017, respectively, under the new
Continental Resources, Inc. and Subsidiaries
Notes to Unaudited Condensed Consolidated Financial Statements

standard, which are reflected in "Benefit for income taxes" in the unaudited condensed consolidated statements of comprehensive loss.
ASU 2016-09 also removed the requirement that entities present excess tax benefits and deficiencies as offsetting cash flows from financing and operating activities in the statement of cash flows. Instead, ASU 2016-09 requires cash flows related to excess tax benefits and deficiencies be classified as operating activities in the same manner as other cash flows related to income taxes. The Company has elected to apply this guidance on a prospective basis. Accordingly, the cash flow presentation of excess tax benefits and deficiencies in periods prior to January 1, 2017, if applicable, will not be adjusted to conform to current period presentation.
The Company has elected to continue its historical accounting practice of estimating forfeitures in determining the amount of stock-based compensation expense to recognize. Therefore, the adoption of ASU 2016-09 does not have an impact on the amount of stock-based compensation expense to be recognized by the Company on non-vested restricted stock awards.
Business combinations – In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is deemed to be a business. Determining whether a transferred set constitutes a business is important because the accounting for a business combination differs from that of an asset acquisition. The definition of a business also affects the accounting for dispositions. Under the new standard, when substantially all of the fair value of assets acquired is concentrated in a single asset, or a group of similar assets, the assets acquired would not represent a business and business combination accounting would not be required. The new standard may result in more transactions being accounted for as asset acquisitions rather than business combinations. The standard is effective for interim and annual periods beginning after December 15, 2017 and shall be applied prospectively. The Company early adopted ASU 2017-01 as of January 1, 2017, which had no significant impact on the Company's financial statements as of and for the three and six months ended June 30, 2017.
New accounting pronouncements not yet adopted
Revenue recognition and presentation – In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which generally requires an entity to identify performance obligations in its contracts, estimate the amount of consideration to be received in the transaction price, allocate the transaction price to each separate performance obligation, and recognize revenue as obligations are satisfied. Additionally, the standard requires expanded disclosures related to revenue recognition.
Subsequent to the issuance of ASU 2014-09, the FASB issued various clarifications and interpretive guidance to assist entities with implementation efforts, including guidance pertaining to the presentation of revenues on a gross basis (revenues presented separately from associated expenses) versus a net basis. Under this guidance, an entity generally shall record revenue on a gross basis if it controls a promised good or service before transferring it to a customer, whereas an entity shall record revenue on a net basis if its role is to arrange for another entity to provide the goods or services to a customer. Significant judgment may be required in some circumstances to determine whether gross or net presentation is appropriate.
ASU 2014-09 and related interpretive guidance will be effective for interim and annual periods beginning after December 15, 2017 and allows for either full retrospective adoption, meaning the standard is applied to all periods presented in the financial statements, or modified retrospective adoption, meaning the standard is applied only to the most current period presented. The Company plans to adopt the standard on January 1, 2018 using the modified retrospective approach.
The Company continues to evaluate the impact of the new standard on its financial statements, accounting policies and internal controls. Based on assessments performed to date, the standard is not expected to have a material effect on the timing of the Company's revenue recognition or its financial position, results of operations, net income, or cash flows, but is expected to have an impact on the Company's revenue-related disclosures. Additionally, the standard is expected to impact the presentation of future revenues and expenses under the gross-versus-net presentation guidance. Historically, the Company has generally presented its revenues net of transportation costs. The new guidance is expected to result in future revenues and associated transportation expenses for certain of the Company's operated properties being reported on a gross basis. The Company expects changes from net to gross presentation will result in an increase in revenues and a corresponding increase in separately reported transportation expenses, with no net effect on the Company's results of operations, net income, or cash flows. For the three and six months ended June 30, 2017, the Company estimates it had approximately $50 million and $100 million, respectively, of transportation-related charges on operated properties included in "Crude oil and natural gas sales" on the unaudited condensed consolidated statements of comprehensive loss. The Company is not currently able to estimate the impact on the presentation of its future revenues and expenses under the new guidance due to uncertainties with respect to future sales volumes, service costs, locations of producing properties, sales destinations, transportation methods utilized, and changes in the nature, timing, and extent of its arrangements from period to period.

Notes to Unaudited Condensed Consolidated Financial Statements

Leases – In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires companies to recognize a right of use asset and related liability on the balance sheet for the rights and obligations arising from leases with durations greater than 12 months. The standard is effective for interim and annual reporting periods beginning after December 15, 2018 and requires adoption by application of a modified retrospective transition approach.
The Company is currently evaluatingcontinues to evaluate the impact of ASU 2016-02 and is in the process of developing systems and processes to identify, classify, and account for leases within the scope of the new standardguidance and to comply with the related disclosure requirements. Based on its financial statementsan initial review of the new guidance and the Company’s current commitments, the Company anticipates it may be required to recognize lease assets and liabilities related disclosures.

As of June 30, 2015 and December 31, 2014, the Company had $410.3 million and $797.5 million, respectively, of accrued capital expenditures.

Note 4. Derivative Instruments
Crude oil and natural gas derivatives
The Company may utilize crude oil and natural gas swap and collar derivative contracts to economically hedge against the variability in cash flows associated with future sales of crude oil and natural gas production. While the use of these derivative instruments limits the downside risk of adverse price movements, their use also limits future revenues from upward price movements.
The Company recognizes all crude oil and natural gas derivative instruments on the balance sheet as either assets or liabilities measured at fair value. The Company has not designated its crude oil and natural gas derivative instruments as hedges for accounting purposes and, as a result, marks such derivative instruments to fair value and recognizes the changes in fair value in the unaudited condensed consolidated statements of comprehensive income (loss)loss under the caption “Gain (loss) on crude oil and natural gas derivatives, net”, which.
The estimated fair value of derivative contracts is a componentbased upon various factors, including commodity exchange prices, over-the-counter quotations, and, in the case of "Total revenues"collars and written call options, volatility, the risk-free interest rate, and the time to expiration. The calculation of the fair value of collars and written call options requires the use of an option-pricing model. See Note 5. Fair Value Measurements.
Continental Resources, Inc. and Subsidiaries
Notes to Unaudited Condensed Consolidated Financial Statements

With respect to a crude oil or natural gas fixed price swap contract, the counterparty is required to make a payment to the Company if the settlement price for any settlement period is less than the swap price, and the Company is required to make a payment to the counterparty if the settlement price for any settlement period is greater than the swap price. For a crude oil or natural gas collar contract, the counterparty is required to make a payment to the Company if the settlement price for any settlement period is below the floor price, and the Company is required to make a payment to the counterparty if the settlement price for any settlement period is above the ceiling price. Neither party is required to make a payment to the other party if the settlement price for any settlement period is between the floor price and the ceiling price.
The Company’s crude oil andAt June 30, 2017, the Company had outstanding natural gas derivative contracts are settled based upon reported settlement prices on commodity exchanges, with crude oil derivative settlements based on Inter-Continental Exchange (“ICE”) pricing for Brent crude oil and natural gas derivative settlements based on NYMEX Henry Hub pricing. The estimated fair value of derivative contracts is based upon various factors, including commodity exchange prices, over-the-counter quotations, and, in the case of collars and written call options, volatility, the risk-free interest rate, and the time to expiration. The calculation of the fair value of collars and written call options requires the use of an option-pricing model. See Note 5. Fair Value Measurements.

Diesel fuel derivatives
In March 2016, theThe Company has entered into diesel fuel swap derivative contracts to economically hedge against the variability in cash flows associated with future purchases of diesel fuel for use in drilling activities. The Company has hedged approximately 19six million gallons of diesel fuel over the period from July 20162017 to December 2017 at a weighted average price of $1.41$1.45 per gallon. With respect to these diesel fuel swap contracts, the counterparty is required to make a payment to the Company if the settlement price for any settlement period is greater than the swap price, and the Company is required to make a payment to the counterparty if the settlement price for any settlement period is less than the swap price. The diesel fuel swap contracts are settled based upon reported NYMEX settlement prices for New York Harbor ultra-low sulfur diesel fuel.

The Company recognizes its diesel fuel derivative instruments on the balance sheet as either assets or liabilities measured at fair value. The estimated fair value is based upon various factors, including commodity exchange prices, over-the-counter quotations, the risk-free interest rate, and time to expiration. The Company has not designated its diesel fuel derivative instruments as hedges for accounting purposes and, as a result, marks the derivative instruments to fair value and recognizes the changes in fair value in the unaudited condensed consolidated statements of comprehensive income (loss)loss under the caption “Operating costs and expensesNet gain(gain) loss on sale of assets and other.” For

Note 5. Fair Value Measurements
The Company follows a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy categorizes assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. The three levels are defined as follows:
Level 1: Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets as of the reporting date.
Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data. These are inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date.
Continental Resources, Inc. and Subsidiaries
Notes to Unaudited Condensed Consolidated Financial Statements

Level 3: Unobservable inputs that are not corroborated by market data and may be used with internally developed methodologies that result in management’s best estimate of fair value.
A financial instrument’s categorization within the hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Level 1 inputs are given the highest priority in the fair value hierarchy while Level 3 inputs are given the lowest priority. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the placement of assets and liabilities within the levels of the hierarchy. As Level 1 inputs generally provide the most reliable evidence of fair value, the Company uses Level 1 inputs when available. The Company’s policy is to recognize transfers between the hierarchy levels as of the beginning of the reporting period in which the event or change in circumstances caused the transfer.
Assets and Liabilities Measured at Fair Value on a Recurring Basis
The Company's derivative instruments are reported at fair value on a recurring basis. In determining the fair values of swap contracts, a discounted cash flow method is used due to the unavailability of relevant comparable market data for the Company’s exact contracts. The discounted cash flow method estimates future cash flows based on quoted market prices for forward commodity prices and a risk-adjusted discount rate. The fair values of swap contracts are calculated mainly using significant observable inputs (Level 2). Calculation of the fair values of collars and written call options requires the use of an industry-standard option pricing model that considers various inputs including quoted forward prices for commodities, time value, volatility factors, and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. These assumptions are observable in the marketplace or can be corroborated by active markets or broker quotes and are therefore designated as Level 2 within the valuation hierarchy. The Company’s calculation of fair value for each of its derivative positions is compared to the counterparty valuation for reasonableness.
The following tables summarize the valuation of financial instruments by pricing levels that were accounted for at fair value on a recurring basis as of June 30, 20162017 and December 31, 2015.2016.

Assets Measured at Fair Value on a Nonrecurring Basis
Certain assets are reported at fair value on a nonrecurring basis in the condensed consolidated financial statements. The following methods and assumptions were used to estimate the fair values for those assets.
Continental Resources, Inc. and Subsidiaries
Notes to Unaudited Condensed Consolidated Financial Statements

Asset Impairments – Proved crude oil and natural gas properties are reviewed for impairment on a field-by-field basis each quarter. The estimated future cash flows expected in connection with the field are compared to the carrying amount of the field to determine if the carrying amount is recoverable. If the carrying amount of the field exceeds its estimated undiscounted future cash flows, the carrying amount of the field is reduced to its estimated fair value. Due to the unavailability of relevant comparable market data, a discounted cash flow method is used to determine the fair value of proved properties. The discounted cash flow method estimates future cash flows based on the Company's estimates of future crude oil and natural gas production, commodity prices based on commodity futures price strips adjusted for differentials, operating costs, and a risk-adjusted discount rate. The fair value of proved crude oil and natural gas properties is calculated using significant unobservable

inputs (Level 3). The following table sets forth quantitative information about the significant unobservable inputs used by the Company to calculate the fair value of proved crude oil and natural gas properties using a discounted cash flow method. 
Unobservable Input  Assumption
Future production  Future production estimates for each property
Forward commodity prices  Forward NYMEX strip prices through 20202021 (adjusted for differentials), escalating 3% per year thereafter
Operating costs  Estimated costs for the current year, escalating 3% per year thereafter
Productive life of field  Ranging from 0 to 3339 years
Discount rate  10%
Unobservable inputs to the fair value assessment are reviewed quarterly and are revised as warranted based on a number of factors, including reservoir performance, new drilling, crude oil and natural gas prices, changes in costs, technological advances, new geological or geophysical data, or other economic factors. Fair value measurements of proved properties are reviewed and approved by certain members of the Company’s management.
ProvedFor the three and six months ended June 30, 2017 the Company determined the carrying amounts of certain proved properties were reviewednot recoverable from future cash flows, and therefore, were impaired. Impairments of proved properties amounted to $81.5 million and $82.3 million for impairment atthe three and six months ended June 30, 20162017, respectively. The 2017 year to date impairments reflect fair value adjustments primarily concentrated in the Arkoma Woodford field ($81.2 million, all in the second quarter) and June 30, 2015. various non-core areas in the North and South regions ($1.1 million, including $0.3 million in the second quarter). The impaired properties were written down to their estimated fair value at the time of impairment of approximately $72 million.
For the three and six months ended June 30, 2016, estimated future net cash flows were determined to be in excess of cost basis, therefore no impairment was recorded for the Company’s proved crude oil and natural gas properties. For the three and six months ended June 30, 2015, the Company determined the carrying amounts of certain proved properties were not recoverable from future cash flows at that time and, therefore, were impaired. Impairments of proved properties for the three and six months ended June 30, 2015 totaled $5.0 million and $75.0 million, respectively, and were primarily concentrated in an emerging area with minimal production and costly reserve additions ($41.2 million, including $5.0 million in the 2015 second quarter), the Medicine Pole Hills units ($14.7 million), various legacy areas in the South region ($11.0 million), and non-Bakken areas of North Dakota and Montana ($8.1 million). The impaired properties were written down to their estimated fair value totaling approximately $38.2 million as of June 30, 2015.those periods.
Certain unproved crude oil and natural gas properties were impaired during the three and six months ended June 30, 20162017 and 2015,2016, reflecting recurring amortization of undeveloped leasehold costs on properties the Company expects will not be transferred to proved properties over the lives of the leases based on drilling plans, experience of successful drilling, and the average holding period.

The fair value of the note payable is determined using a discounted cash flow approach based on the interest rate and payment terms of the note payable and an assumed discount rate. The fair value of the note payable is significantly influenced by the discount rate assumption, which is derived by the Company and is unobservable. Accordingly, the fair value of the note payable is classified as Level 3 in the fair value hierarchy.

Credit facility borrowings on its revolving credit facility at June 30, 2016 and December 31, 2015, respectively. Borrowings bear interest at market-based interest rates plus a margin based on the terms of the borrowing and the credit ratings assigned to the Company's senior, unsecured, long-term indebtedness. The weighted-average interest rate on outstanding credit facility borrowings at June 30, 20162017 was 2.2%2.85%.
The Company had approximately $1.86$1.87 billion of borrowing availability on its revolving credit facility at June 30, 20162017 and incurs commitment fees based on currently assigned credit ratings of 0.30% per annum on the daily average amount of unused borrowing availability under its revolving credit facility.
The revolving credit facility contains certain restrictive covenants including a requirement that the Company maintain a consolidated net debt to total capitalization ratio of no greater than 0.65 to 1.00. This ratio represents the ratio of net debt (calculated as total face value of debt plus outstanding letters of credit less cash and cash equivalents) divided by the sum of net debt plus total shareholders' equity plus, to the extent resulting in a reduction of total shareholders’ equity, the amount of any non-cash impairment charges incurred, net of any tax effect, after June 30, 2014.

Litigation In November 2010, a putative class action was filed in the District Court of Blaine County,county, Oklahoma by Billy J. Strack and Daniela A. Renner as trustees of certain named trusts and on behalf of other similarly situated parties against the Company. The Petition alleged the Company improperly deducted post-production costs from royalties paid to plaintiffs and other royalty interest owners from crude oil and natural gas wells located in Oklahoma. The plaintiffs alleged a number of claims, including breach of contract, fraud, breach of fiduciary duty, unjust enrichment, and other claims and seek recovery of compensatory damages, interest, punitive damages and attorney fees on behalf of the proposed class. On November 3, 2014, plaintiffs filed an Amended Petition that did not add any substantive claims, but sought a “hybrid class action” in which they sought certification of certain claims for injunctive relief, reserving the right to seek a further class certification on money damages in the future. Plaintiffs filed an Amended Motion for Class Certification on January 9, 2015, that modified the proposed class to royalty owners in Oklahoma production from July 1, 1993, to the present (instead of 1980 to the present) and sought certification of over 45 separate “issues” for injunctive or declaratory relief, again, reserving the right to seek a further class certification of money damages in the future. The Company responded to the petition, its amendment, and the motions for class certification denying the allegations and raising a number of affirmative defenses and legal arguments to each of the claims and filings. Certain discovery was undertaken and the “hybrid” motion was briefed by plaintiffs and the Company. A hearing on the “hybrid” class certification was held on June 1st1 and 2nd,2, 2015.

Note 10. Income Taxes
Income taxes are accounted for using the liability method under which deferred income taxes are recognized for the future tax effects of temporary differences between financial statement carrying amounts and the tax basis of existing assets and liabilities using the enacted statutory tax rates in effect at period-end. The effect on deferred taxes for a change in tax rates is recognized in income in the period that includes the enactment date. The Company’s policy is to recognize penalties and interest related to unrecognized tax benefits, if any, in income tax expense. A valuation allowance for deferred tax assets is recorded when it is more likely than not that the benefit from the deferred tax asset will not be realized.
The Company's benefit for income taxes totaled $37.9 million and $31.8 million for the three and six months ended June 30, 2017, respectively. The Company's benefit for income taxes totaled $72.6 million and $194.0 million for the three and six months ended June 30, 2016, respectively. These amounts differ from the amounts computed by applying the United States statutory federal income tax rate to net loss before income taxes.

Overview
We are an independent crude oil and natural gas company engaged in the exploration, development and production of crude oil and natural gas. We derive the majority of our operating income and cash flows from the sale of crude oil and natural gas and expect this to continue in the future. Our operations are primarily focused on exploration and development activities in the Bakken field of North Dakota and Montana and the SCOOP STACK, and Northwest CanaSTACK areas of Oklahoma.
Business Environment and Outlook
Commodity prices showed some signs of stabilization and recovery in the second quarter of 2016, but still remain volatile and unpredictable due to domestic and global supply and demand factors. In light of the challenges facing our industry, our primary business strategies for 2016 continue to2017 focus on: (1) optimizing cash flows through operating efficiencies and cost reductions, (2) high-grading investments based on rates of return and opportunities to convert undeveloped acreage to acreage held by production, (2) improving cash flows through operating efficiencies, cost reductions, and optimized completions, (3) balancingmanaging capital spending with cash flows to minimize the incurrence of new borrowingsdebt and maintain ample liquidity.liquidity and financial flexibility, and (4) pursuing opportunities to further reduce debt using proceeds from potential sales of non-strategic assets.

The 11%6% decrease in crude oil production for the second quarter was driven by decreased production from our North region properties in North Dakota Bakken, Montana Bakken, and the Red River units due to a combination ofnatural declines in production coupled with reduced drilling activities over the past year in response to low crude oil prices. North Dakota Bakken crude oil production decreased 347 MBbls, or 4%, and Montana Bakken production decreased 229 MBbls, or 29%, while crude oil production in the Red River units decreased 99 MBbls, or 10%, from the prior year second quarter. The decreased crude oil production in North Dakota Bakken was partially mitigated by new well production generated in recent months from increased


well completion activities in 2017. Additionally, crude oil production in SCOOP decreased 308 MBbls, or 17%, due to natural declines in production and reduced drilling and completion activities in those areas. North Dakota Bakken crude oil production decreased 1,377 MBbls, or 14%, and Montana Bakken production decreased 242 MBbls, or 24%, while production in the Red River units decreased 145 MBbls, or 13%, over the prior year second quarter.activities. These decreases were partially offset by an increase of 281


293 MBbls, or 95%, in crude oil production from our STACK/Northwest CanaSTACK properties due to additional wells being completed and producing resulting fromas a result of a shift in our welldrilling and completion activities away from the Bakken to higherhigh rate-of-return areasopportunities in Oklahoma.that area.
The 13%17% increase in natural gas production for the second quarter was driven by increased production from our properties in the STACK Northwest Cana and SCOOP playsplay due to additional wells being completed and producing subsequent to June 30, 2015.2016. Natural gas production in STACK/Northwest CanaSTACK increased 3,8817,699 MMcf, or 173%126%, and SCOOPover the prior year second quarter. Additionally, natural gas production in North Dakota Bakken increased 1,042907 MMcf, or 4%7%, over the prior year second quarter. Additionally, North Dakota Bakken natural gas production increased 990 MMcf, or 8%,quarter due to an increasenew well production generated in gas capturerecent months from non-operated properties and resulting increase in volumes produced and delivered to market.increased well completion activities. These increases were partially offset by decreases in production from various other areas in our North and South regions primarily due to natural declines in production.reduced drilling activities over the past year.
The increase in natural gas production as a percentage of our total production from 34% in the second quarter of 2015 to 39% in the second quarter of 2016 to 45% in the second quarter of 2017 primarily resulted from significant increasesan increase in STACK Northwest Cana and SCOOPnatural gas production over the past year due to the aforementioneda shift in our well completiondrilling activities away from the Bakken to higher rate-of-return areasthe STACK play in Oklahoma. Our properties
In conjunction with our planned increase in STACK, Northwest Cana and SCOOP typically produce a higher concentration of liquids-rich natural gas comparedcapital spending for 2017 relative to oil-weighted properties in the Bakken. For the remainder of 2016, we expect to continue focusing our well completion activities on our Oklahoma properties. Accordingly, we expect our natural gas production may increase to approximately 40% of our total productionwill average between 230,000 and 240,000 Boe per day for the full year of 2016. As crude oil prices recover, we expect2017 compared to increase our completion activities in the Bakken and shift ouraverage daily production back to a higher proportion of crude oil.216,912 Boe per day for 2016.
Revenues
Our revenues primarily consist of sales of crude oil and natural gas and gains and losses resulting from changes in the fair value of our crude oil and natural gas derivative instruments.
Crude Oil and Natural Gas Sales. Crude oil and natural gas sales for the second quarter of 20162017 were $525.7$626.5 million, a 33% decrease19% increase from sales of $790.1$525.7 million for the 20152016 second quarter due to decreasesincreases in commodity prices and total sales volumes. If commodity prices remain at current levels, we expect our 2017 crude oil and natural gas revenues will continue to be higher than 2016 levels, the extent of which is uncertain due to the unpredictable nature of commodity prices.
Our crude oil sales prices averaged $38.38$41.91 per barrel in the 20162017 second quarter, a decreasean increase of 23%9% compared to $49.84$38.38 per barrel for the 20152016 second quarter due to lowerhigher crude oil market prices. The differential between NYMEX West Texas Intermediate ("WTI") calendar month crude oil prices and our realized crude oil prices averaged $7.21$6.31 per barrel for the 20162017 second quarter compared to $8.18$7.21 for the 20152016 second quarter. The improved differential was primarily due to increased use of pipeline transportation to move our North region crude oil to market with less dependence on more costly rail transportation, along withthe significant growth in our South region production which typically has lower transportation costs compared to the Bakken due to its relatively close proximity to regional refineries and the crude oil trading hub in Cushing, Oklahoma.Oklahoma, along with improved realizations resulting from new pipeline takeaway capacity and additional markets becoming available in 2017 for Bakken production.
Our natural gas sales prices averaged $2.63 per Mcf for the 2017 second quarter, a 101% increase compared to $1.31 per Mcf for the 2016 second quarter a 43% decrease compared to $2.31 per Mcf for the 2015 second quarter due to lowerhigher market prices for natural gas and natural gas liquids (“NGLs”("NGLs") along with the amendment of certain. The discount between our realized natural gas sales agreements in 2016.prices and NYMEX Henry Hub calendar month natural gas prices improved from $0.65 per Mcf for the 2016 second quarter to $0.56 per Mcf for the 2017 second quarter. The majority of our natural gas production is sold at our lease locations to midstream purchasers with price realizations impacted by the volume and value of NGLs that purchasers extract from our sales stream. The difference between our realized natural gas sales prices and NYMEX Henry Hub calendar month natural gas prices was a discount of $0.65 per Mcf for the 2016 second quarter compared to a discount of $0.33 per Mcf for the 2015 second quarter. NGL prices remained depressed in the 2016 second quarterhave increased over prior year levels in conjunction with lowincreased crude oil prices, which, along with our amended natural gas sales agreements, reduced the value ofresulting in improved price realizations for our natural gas sales stream and unfavorably impactedcompared to the difference between our realized prices and Henry Hub benchmark pricing. If NGL prices do not recover from current levels, the prices we receive for the sale of our natural gas stream for the remainder of 2016 may continue to be lower than Henry Hub benchmark prices.prior year second quarter.
Commodity prices showed some signs of stabilization and recovery inTotal sales volumes for the second quarter of 2017 increased 733 MBoe, or 4%, compared to the 2016 but still remain volatilesecond quarter, reflecting an increase in our pace of drilling and we are unable to predictcompletion activities in the impact future price changes may have on our full year 2016 revenues and differentials.
2017 second quarter. For the second quarter of 2016,2017, our crude oil sales volumes decreased 13%5% from the comparable 20152016 period, while our natural gas sales volumes increased 13%17%, reflecting the shift in our well completiondrilling activities over the past year away from oil-weighted properties in the Bakken to areas in Oklahoma with higher concentrations of liquids-rich natural gas.
Derivatives. Changes in natural gas prices during the second quarter of 20162017 had an unfavorablea favorable impact on the fair value of our natural gas derivatives, which resulted in negativepositive revenue adjustments of $82.3$28.0 million for the period, representing $121.0$24.4 million of non-cash losses on derivatives partially offset by $38.7gains and $3.6 million of cash gains. Our revenues may continue to be significantly impacted, either positively or negatively, by changes in the fair value of our derivative instruments as a result of volatility in natural gas prices.


Operating Costs and Expenses
Production Expenses. Production expenses decreased $17.6increased $8.4 million, or 19%11%, from $91.7 million for the second quarter of 2015 to $74.1 million for the second quarter of 2016.2016 to $82.5 million for the second quarter of 2017. Production expenses on a per-Boe basis decreasedincreased to $3.99 for the 2017 second quarter compared to $3.72 for the 2016 second quarter compared to $4.39 for the 2015 second quarter. These decreases primarilyincreases resulted from curtailed spending and reduced service costs being realized in response to depressed commodity prices, increased availability and use of water gathering and recycling facilities over the prior year period, and a higher portion of our production coming from natural gas wells in Oklahoma which typically have lower operating costs compared to crude oil wellsan increase in the Bakken.number of producing wells, an increase in workover-related activities in the North region aimed at enhancing production from producing properties, and increased water handling and disposal expenses associated with increased production in the South region.
Production Taxes and Other Expenses.Taxes. Production taxes and other expenses decreased $22.4increased $2.8 million, or 36%7%, to $41.9 million for the second quarter of 2017 compared to $39.1 million for the second quarter of 2016 compared to $61.5 million for the second quarter of 2015 primarily due to lowerhigher crude oil and natural gas revenues resulting from decreasesincreases in commodity prices over the prior year period. Production taxes are generally based on the wellhead values of production and vary by state. Production taxes as a percentage of crude oil and natural gas revenues were 6.7% for the second quarter of 2017 compared to 7.4% for the second quarter of 2016, compared to 7.8% for the second quarter of 2015, the decrease of which resulted from significant growth over the past year in our STACK Northwest Cana and SCOOP operations and resulting increase in revenues coming from Oklahoma, which has lower production tax rates compared to North Dakota. We expectThe production tax rate on Oklahoma wells that commenced production after July 1, 2015 is currently 2% of crude oil and natural gas revenues for the first 36 months of production and 7% thereafter. The production tax rate on new wells in North Dakota is currently 10% of crude oil revenues.
Through June 30, 2017, Oklahoma had a crude oil and natural gas production tax incentive for wells that commenced production between July 1, 2011 and July 1, 2015, which allowed for a 1% production tax rate for the first 48 months of production. In May 2017, new legislation was signed into law in Oklahoma that increased the incentive tax rate from 1% to 4% on those wells that began producing between July 1, 2011 and July 1, 2015. After the 48 month incentive period ends, the tax rate on such wells increases to 7%. The new 4% tax rate on these wells went into effect on July 1, 2017 and may cause our average production tax rate for the remainder of 2016 will continue to trend lower than 2015 levels as our operationshigher in Oklahoma continuefuture periods relative to grow in significance and given the passing2017 second quarter, the extent of legislation in North Dakota in 2015 that decreased the combined production tax rate from 11.5% to 10.0% of crude oil revenues in North Dakota effective January 1, 2016.     which is uncertain.

Estimated proved reserves are a key component in our computation of DD&A expense. Holding all other factors constant, if proved reserves are revised downward, the rate at which we record DD&A expense would increase. Downwardincreases. Conversely, if proved reserves are revised upward, the rate at which we record DD&A expense decreases. Upward revisions ofto proved reserves in 2016 prompted by depressed2017 due in part to an improvement in commodity prices contributed to an increasea decrease in our DD&A rate for crude oil and natural gas properties in the second quarter of 20162017 compared to the priorsecond quarter of 2016. Additionally, improvements in drilling efficiencies and optimized completion technologies over the past year period. If commodity prices decline further, additional downward revisionshave resulted in a significant improvement in the quantity of proved reserves may occur infound and developed per dollar invested, which also contributed to the future, which may be significant and would result in an increasereduction in our DD&A rate. We are unable to predictrate in the timing and amount of future reserve revisions or the impact such revisions may have on our future DD&A rate.current period.
Property Impairments. Total property impairments decreased $10.8increased $57.2 million, or 14%87%, to $123.3 million for the 2017 second quarter compared to $66.1 million for the 2016 second quarter comparedprimarily due to $76.9an increase in proved property impairments partially offset by lower unproved property impairments as discussed below.


Proved property impairments totaled $81.5 million for the 20152017 second quarter.quarter and were primarily concentrated in the Arkoma Woodford field for which we determined the carrying amount of the field was not recoverable from future cash flows, and therefore, was impaired. There were no proved property impairments recognized in the second quarter of 2016 compared to $5.0 million of such impairments in the second quarter of 2015. This decrease resulted from differences in the timing and severity of commodity price declines and resulting impact on fair value assessments and impairments between periods. As a result of the impairments and DD&A recognized to date coupled with an improvement in commodity prices in June 2016, our proved properties are carried at values that did not exceed estimated future net cash flows at June 30, 2016 and required no impairment during the 2016 second quarter.2016.


Estimated reserves are a key component in assessing proved properties for impairment. If commodity prices decline further, downward revisions of reserves may be significant in the future and could result in impairments of proved properties in the remainder of 2016. We are unable to predict the timing and amount of future reserve revisions or the impact such revisions may have on future impairments, if any.
Impairments of non-producing properties decreased $5.7$24.3 million, or 8%37%, to $41.8 million for the 2017 second quarter compared to $66.1 million for the 2016 second quarter compared to $71.8 million for the 2015 second quarter. The decrease was due to a lower balance of unamortized leasehold costs in the current year due in part to property dispositions and reduced land capital expenditures over the past year, along with changes in the timing and magnitude of amortization of undeveloped leasehold costs between periods resulting from changes in the Company's estimates of undeveloped properties not expected to be developed before lease expiration.
General and Administrative ("G&A") Expenses. Total G&A expenses decreased $7.9increased $3.0 million, or 18%8%, tofrom $36.2 million for the second quarter of 2016 from $44.2to $39.2 million for the second quarter of 2015.2017. Total G&A expenses include non-cash charges for equity compensation of $11.8$9.1 million and $16.2$11.8 million for the second quarters of 20162017 and 2015,2016, respectively. G&A expenses other than equity compensation included in the total G&A expense figure above totaled $30.1 million for the 2017 second quarter, an increase of $5.7 million, or 23%, compared to $24.4 million for the 2016 second quarter, a decrease of $3.6 million, or 13%, compared to the 2015 second quarter.

Interest expense increased $3.5decreased $9.2 million, or 4%11%, to $72.7 million for the second quarter of 2017 compared to $81.9 million for the second quarter of 2016 compared to $78.4 million for the second quarter of 2015 due to an increasea decrease in our weighted average outstanding long-term debt obligations and higher borrowing costs incurred on our credit facility and three-year term loan resulting from downgradesprimarily as a result of the November 2016 redemptions of our credit rating in February 2016.$200 million of 2020 Notes and $400 million of 2021 Notes. Our weighted average outstanding long-term debt balance for the 20162017 second quarter was approximately $7.3$6.6 billion with a weighted average interest rate of 4.3%4.2%, compared to averages of $7.1$7.3 billion and 4.3% for the 20152016 second quarter. The lower interest expense associated with reduced debt was partially offset by higher interest expense being incurred on our variable-rate credit facility and term loan borrowings due to an increase in outstanding debt resulted from borrowings incurred subsequent to June 30, 2015 to fund our capital spending.market interest rates in 2017.
Income Taxes. We recorded an income tax benefit for the second quarter of 20162017 of $72.6$37.9 million compared to income tax expensea benefit of $4.1$72.6 million for the second quarter of 2015,2016, resulting in effective tax rates of approximately 38%37% and 91%38%, respectively, after taking into account permanent taxable differences, valuation allowances, and valuation allowances.other items. For the second quarters of 20162017 and 2015,2016, we provided for income taxes at a combined federal and state tax rate of 38% of pre-tax income (loss)losses generated by our operations in the United States.

The 4%13% decrease in crude oil production for year to date 20162017 was driven primarily by decreased production from our North region properties in North Dakota Bakken, Montana Bakken and the Red River units due to a combination of natural declines in production andcoupled with reduced drilling and completion activities over the past year in those areas.response to low crude oil prices. North Dakota Bakken crude oil production decreased 1,0012,584 MBbls, or 5%15%, and Montana Bakken production decreased 607432 MBbls, or 28%, while production in the Red River units decreased 275211 MBbls, or 13%11%, overfrom the prior year period. The decreased crude oil production in North Dakota Bakken was partially mitigated by new well production generated in recent months from increased well


completion activities in 2017. Additionally, crude oil production in SCOOP decreased 626 MBbls, or 17%, due to natural declines in production and reduced drilling activities. These decreases were partially offset by increasesan increase of 579 MBbls, or 103%, in crude oil production from our STACK properties


in the STACK/Northwest Cana and SCOOP plays which increased 503 MBbls and 378 MBbls, respectively,due to additional wells being completed and producing resulting fromas a result of a shift in our welldrilling and completion activities away from the Bakken to higherhigh rate-of-return areasopportunities in Oklahoma.that area.
The 23%14% increase in natural gas production for year to date 20162017 was driven by increased production from our properties in the STACK/Northwest Cana and SCOOP playsSTACK play due to additional wells being completed and producing subsequent to June 30, 2015.2016. Natural gas production in STACK/Northwest CanaSTACK increased 6,77115,687 MMcf, or 173%, and SCOOP production increased 7,236 MMcf, or 17%147%, over the prior year period. Additionally, North Dakota Bakken production increased 3,942 MMcf, or 17%, due to anThis increase in gas capture from non-operated properties and resulting increase in volumes produced and delivered to market. These increases werewas partially offset by decreases of 1,652 MMcf (6%) and 440 MMcf (22%) in North Dakota Bakken and Montana Bakken natural gas production, from various areas in our North and South regions primarilyrespectively, due to natural declines in production.
Our reductionproduction and reduced drilling activities over the past year. The decreased natural gas production in capital spending and deferral of certainNorth Dakota Bakken was partially mitigated by new well production generated in recent months from increased well completion activities has adversely impacted our rate of production and our 4% growth in total production realized for year to date 2016 compared to year to date 2015 is not expected to be sustained forduring the remainder of 2016. We expect our rate of production to slow for the remainder of 2016 and may average between 210,000 and 220,000 Boe per day for the full year of 2016 compared to average daily production of 221,715 Boe per day for full year 2015.2017 second quarter.
Revenues
Crude Oil and Natural Gas Sales. Crude oil and natural gas sales for year to date 20162017 were $929.3 million,$1.26 billion, a 32% decrease36% increase from sales of $1.37 billion$929.3 million for the same period in 20152016 due to a significant decrease39% increase in realized commodity prices partially offset by an increasea 2% decrease in total sales volumes.
Our crude oil sales prices averaged $31.76$43.26 per barrel for year to date 2016, a decrease2017, an increase of 29%36% compared to $44.46$31.76 for year to date 20152016 due to lowerhigher crude oil market prices. The differential between NYMEX WTI calendar month average crude oil prices and our realized crude oil price per barrel for year to date 20162017 was $7.51$6.69 per barrel compared to $9.05$7.51 for year to date 2015.2016. The improved differential was primarily due to increased use of pipeline transportation to move our North region crude oil to market with less dependence on more costly rail transportation, along withthe significant growth in our South region production which typically has lower transportation costs compared to the Bakken due to its relatively close proximity to regional refineries and the crude oil trading hub in Cushing, Oklahoma.Oklahoma, along with improved realizations resulting from new pipeline takeaway capacity and additional markets becoming available in 2017 for Bakken production.
Our natural gas sales prices averaged $1.33$2.81 per Mcf for year to date 2016,2017, a 46% decrease111% increase compared to $2.48$1.33 for year to date 20152016 due to lowerhigher market prices for natural gas and NGLs along with the amendment of certain natural gas sales agreements in 2016.NGLs. The differencediscount between our realized natural gas sales prices and NYMEX Henry Hub calendar month natural gas prices was a discount ofimproved from $0.69 per Mcf for year to date 2016 compared to a discount of $0.31$0.43 per Mcf for year to date 2017. The majority of our natural gas production is sold at our lease locations to midstream purchasers with price realizations impacted by the comparable 2015 period.volume and value of NGLs that purchasers extract from our sales stream. NGL prices in the first half of 2016 remained depressedhave increased over prior year levels in conjunction with lowincreased crude oil prices, which, along with our amended natural gas sales agreements, reduced the value ofresulting in improved price realizations for our natural gas sales stream and unfavorably impactedcompared to the difference between our realized prices and Henry Hub benchmark pricing. If NGL prices do not recover from current levels, the prices we receiveprior year.
Total sales volumes for the sale of our natural gas stream for the remainder of 2016 may continueyear to be lower than Henry Hub benchmark prices.     
date 2017 decreased 944 MBoe, or 2%, compared to year to date 2016. For year to date 2016,2017, our crude oil sales volumes decreased 5%12% from the comparable 20152016 period, while our natural gas sales volumes increased 23%14%, reflecting the shift in our well completiondrilling activities over the past year away from oil-weighted properties in the Bakken to areas in Oklahoma with higher concentrations of liquids-rich natural gas.
At various times we have stored crude oil due to pipeline line fill requirements, low commodity prices, or marketing disruptions or we have sold crude oil from inventory. These actions result in differences between produced and sold crude oil volumes and caused crude oil sales volumes to be lowerhigher than crude oil production by 80115 MBbls for year to date 2016.2017.
Derivatives. Changes in natural gas prices during the six months ended June 30, 20162017 had an unfavorablea favorable impact on the fair value of our natural gas derivatives, which resulted in negativepositive revenue adjustments of $40.1$74.8 million for the period, representing $118.1$72.1 million of non-cash losses on derivatives partially offset by $78.0gains and $2.7 million of cash gains. 
Operating Costs and Expenses
Production Expenses. Production expenses decreased $32.0increased $2.6 million, or 17%2%, from $184.7 million for year to date 2015 to $152.7 million for year to date 2016.2016 to $155.3 million for year to date 2017. Production expenses on a per-Boe basis decreasedincreased to $3.74$3.89 for year to date 20162017 compared to $4.70$3.74 for the comparable 20152016 period. These decreases primarilyincreases resulted from curtailed spending and reduced service costs being realized in response to depressed commodity prices, increased availability and use of water gathering and recycling facilities over the prior year period, and a higher portion of our production coming from natural gas wells in Oklahoma which typically have lower operating costs compared to crude oil wellsan increase in the Bakken.number of producing wells, higher costs incurred in the 2017 first quarter from severe weather conditions encountered in the North region that created a challenging operating environment, an increase in workover-related activities in the North region aimed at enhancing production from producing properties, and increased water handling and disposal expenses associated with increased production in the South region.


Production Taxes and Other Expenses.Taxes. Production taxes and other expenses decreased $40.3increased $13.6 million, or 37%20%, to $83.2 million for year to date 2017 compared to $69.6 million for year to date 2016 compared to $109.9 million for year to date 2015 primarily due to lowerhigher crude oil and natural gas revenues resulting primarily from decreasesincreases in commodity prices over the prior year period. Production taxes as a percentage of crude oil and natural gas revenues were 6.6% for year to date 2017 compared to 7.5% for year to date 2016, compared to 8.0% for year to date 2015, the decrease of which resulted from significant growth over the


past year in our STACK Northwest Cana and SCOOP operations and resulting increase in revenues coming from Oklahoma, which has lower production tax rates compared to North Dakota. We expect
Through June 30, 2017, Oklahoma had a crude oil and natural gas production tax incentive for wells that commenced production between July 1, 2011 and July 1, 2015, which allowed for a 1% production tax rate for the first 48 months of production. In May 2017, new legislation was signed into law in Oklahoma that increased the incentive tax rate from 1% to 4% on those wells that began producing between July 1, 2011 and July 1, 2015. After the 48 month incentive period ends, the tax rate on such wells increases to 7%. The new 4% tax rate on these wells went into effect on July 1, 2017 and may cause our average production tax rate for the remainder of 2016 will continue to trend lower than 2015 levels as our operationshigher in Oklahoma continuefuture periods relative to grow in significance and given the passing2017 second quarter, the extent of legislation in North Dakota in 2015 that decreased the combined production tax rate from 11.5% to 10.0% of crude oil revenues in North Dakota effective January 1, 2016.which is uncertain.

The increaseUpward revisions to proved reserves over the past year due in part to an improvement in commodity prices contributed to a decrease in our DD&A rate for crude oil and natural gas properties in 2017 compared to 2016. Additionally, improvements in drilling efficiencies and optimized completion technologies over the current periodpast year have resulted from downward revisionsin a significant improvement in the quantity of proved reserves at year-end 2015found and in 2016 prompted by depressed commodity prices. If commodity prices decline further, additional downward revisions of proved reserves may occur indeveloped per dollar invested, which also contributed to the future, which may be significant and would result in an increasereduction in our DD&A rate.

Total property impairments decreased $79.4increased $29.7 million, or 35%20%, to $174.7 million for year to date 2017 compared to $145.0 million for year to date 2016 comparedprimarily due to $224.4an increase in proved property impairments partially offset by lower unproved property impairments as discussed below.
Proved property impairments totaled $82.3 million for year to date 20152017 and were primarily due to a decreaseconcentrated in proved property impairments.the Arkoma Woodford field for which we determined the carrying amount of the field was not recoverable from future cash flows, and therefore, was impaired. There were no proved property impairments recognized for year to date 2016 compared2016.

The decrease resulted from differenceswas due to a lower balance of unamortized leasehold costs in the current year due to property dispositions and reduced land capital expenditures over the past year, along with changes in the timing and severitymagnitude of commodity price declines andamortization of undeveloped leasehold costs between periods resulting impact on fair value assessments and impairments between periods. The prolonged decrease in commodity prices in 2015 triggered significant impairments of proved properties throughout 2015. As a result of the impairments and DD&A recognized to date coupled with an improvement in commodity prices in June 2016, our proved properties are carried at values that did not exceed estimated future net cash flows at June 30, 2016 and required no impairment during the six month period.

The decreaseincrease in G&A expenses other than equity compensation was primarily due to a reductionan increase in employee related costscompensation and other efforts to reduce spendingbenefits in 2017 in response to depressedthe stabilization and improvement in commodity prices. The decreaseprices in equity compensation expense was primarily due to an increase in the estimated rate of forfeitures of unvested restricted stock based on historical experience, which resulted in lower recognition of expense inlate 2016.
Interest Expense. Year to date interest expense increased $9.4decreased $19.0 million, or 6%12%, to $162.9$143.9 million compared to $153.5$162.9 million for the comparable 20152016 period due to an increasea decrease in our weighted average outstanding long-term debt obligations and higher borrowing costs incurred on our credit facility and three-year term loan resulting from downgradesprimarily as a result of the November 2016 redemptions of our credit rating in February 2016.$200 million of 2020 Notes and $400 million of 2021 Notes. Our weighted average outstanding long-term debt balance for year to date 20162017 was approximately $7.2$6.6 billion with a weighted average interest rate of 4.3%4.2% compared to averages of $6.7$7.2 billion and 4.5%4.3% for the comparable period in 2015.2016. The lower interest expense associated with reduced debt was partially offset by higher interest expense being incurred on our variable-rate credit facility and term loan borrowings due to an increase in outstanding debt resulted from borrowings incurred subsequent to June 30, 2015 to fund our capital spending.market interest rates in 2017.
Income Taxes. We recorded an income tax benefit for the six months ended June 30, 20162017 of $194.0$31.8 million compared to a benefit of $49.9$194.0 million for the prior year period, resulting in effective tax rates of approximately 38%34% and 27%38%, respectively, after taking into account permanent taxable differences, valuation allowances, and valuation allowances.

Liquidity and Capital Resources
Our primary sources of liquidity have historically been cash flows generated from operating activities, financing provided by our revolving credit facility and the issuance of debt and equity securities. Additionally, non-strategic asset dispositions have provided a significant source of cash flow for use in reducing debt and enhancing liquidity. Building on debt reduction progress made in 2016, we intend to pursue opportunities to further reduce our long-term debt using proceeds from additional potential sales of non-strategic assets; however, no assurance can be given that such asset sales will occur.
At June 30, 2016,2017, we had $16.6$17.2 million of cash and cash equivalents and approximately $1.86$1.87 billion of borrowing availability on our revolving credit facility after considering outstanding borrowings of $880 million and letters of credit. We are focusedAt July 31, 2017, outstanding borrowings totaled $938 million, leaving approximately $1.81 billion of borrowing availability on balancing our 2016credit facility at that date. For 2017, we expect to maintain a disciplined spending approach and plan to manage the level of our capital spending with cash flows in order to minimize new borrowings and maintain ample liquidity. At July 31, 2016, outstanding borrowings totaled $820 million with approximately $1.93 billion of borrowing availability on our credit facility after considering outstanding borrowings and letters of credit.
Based on our 20162017 capital expenditure budget, our forecasted cash flows and projected levels of indebtedness, we expect to maintain compliance with the covenants under our revolving credit facility, three-year term loan, and senior note indentures for at least the next 12 months. Further, we expect to meet in the ordinary course of business other contractual cash commitments to third parties as of June 30, 2016,2017, including those described in Note 7. Commitments and Contingencies in Notes to Unaudited Condensed Consolidated Financial Statements, recognizing we may be required to meet such commitments even if our business plan assumptions were to change. We monitor our capital spending closely based on actual and projected cash flows and have the ability to reduce spending or dispose of assets to preserve liquidity and financial flexibility if needed to fund our operations.

The decreaseincrease in operating cash flows was primarily due to loweran increase in crude oil and natural gas revenues driven by lowerhigher realized commodity prices in 2017 coupled with lower interest expenses, the effects of which were partially offset by lowerincreases in production expenses, production taxes, and general and administrative expenses and an increasea decrease in cash gains on matured natural gas derivatives.
Crude oil and natural gas market prices existing through July 31, 2017 are higher than average market prices for full year 2016. If the commodity price environment existing in the second quarter of 2016 persists or worsens and our rate of production continues to slow,prices remain at current levels, we expect our 2017 operating cash flows for the remainder of 2016 will continue to be lowerhigher than 20152016 levels, the extent of which is uncertain due to the unpredictable nature of commodity prices.


Cash flows used in investing activities
During the six months ended June 30, 20162017 and 2015,2016, we had cash flows used in investing activities (excluding proceeds from asset sales) of $887.3 million and $630.0 million, and $2.0 billion, respectively, related to our capital program, inclusive of exploration and development drilling, property acquisitions, and dry hole costs and property acquisitions.costs. Property acquisitions totaled $14.3$19.2 million and $43.2$14.3 million for the six months ended June 30, 20162017 and 2015,2016, respectively. The decreaseincrease in capital spending was driven by a decreasean increase in our capital budget and related drilling activityand completion activities for 2016. Our cash capital expenditures for 2016 include the payment of amounts owed at December 31, 2015 in connection with our 2015 drilling program and associated $86.5 million decrease in accruals for capital expenditures for the six months ended June 30, 2016.2017.
The use of cash for capital expenditures during the six months ended June 30, 2016 was partially offset by $112.2 million of proceeds received from asset dispositions primarily related to the April 2016 sale of non-core undeveloped leasehold acreage in Wyoming for proceeds of $110.0 million.
WeFor 2017, we currently expect our cash flows used in investing activities, exclusive of any proceeds from asset sales, will be higher than 2016 levels due to our planned increase in drilling and completion activity for 2017. Our non-acquisition capital expenditures for full year 2017 are budgeted to be between $1.75 billion and $1.95 billion compared to $1.07 billion of non-acquisition capital spending for the remainder of 2016 will continue to be lower than 2015 levels due to the significant decrease in our budgeted capital spending to $920 million for 2016, a reduction of 63% compared to $2.5 billion of capital spending in 2015.full year 2016.
Cash flows from financing activities
Net cash used in financing activities for the six months ended June 30, 2017 totaled $36.7 million primarily resulting from net repayments of $25 million on our revolving credit facility during the period using available cash flows from operations.
Net cash provided by financing activities for the six months ended June 30, 2016 was $25.2 million primarily resulting from net borrowings of $32 million on our revolving credit facility during the period. The net increase in borrowings was comprised of $87 million of net borrowings in the 2016 first quarter partially offset by $55 million of net repayments in the 2016 second quarter. The second quarter net repayments resulted from a $110.0 million reduction of credit facility debt using proceeds from the sale of undeveloped leasehold acreage in Wyoming in April 2016, partially offset by additional borrowings during the quarter.
Net cash provided by financing activities for the six months ended June 30, 2015 was $1.05 billion primarily resulting from $1.06 billion of net borrowings on our revolving credit facility during that period.period to fund operations.
We are seekingplan to generally balancemanage the level of our 20162017 capital expenditures with cash flowsspending in order to minimize the incurrence of new borrowings in 2016.debt during the year.
Future Sources of Financing
Although we cannot provide any assurance, we believe funds from operating cash flows, our remaining cash balance and availability under our revolving credit facility should be sufficient to meet our cash requirements inclusive of, but not limited to, normal operating needs, debt service obligations, planned capital expenditures, and commitments for at least the next 12 months.
Our 20162017 capital expenditures budget has been established based on an expectation of available cash flows, with any cash flow deficiencies expected to be funded by borrowings under our revolving credit facility. facility or proceeds from asset sales.
If cash flows are materially impacted by declines in commodity prices, we have the ability to reduce our capital expenditures or utilize the availability of our revolving credit facility if needed to fund our operations. We may choose to access the capital markets for additional financing or capital to take advantage of business opportunities that may arise if such financing can be arranged on favorable terms. Additionally,arise. Further, we may choose to sell additional assets or enter into strategic joint development opportunities in order to obtain funding for our operations and capital program.program if such transactions can be executed on satisfactory terms.
We currently anticipate we will be able to generate or obtain funds sufficient to meet our short-term and long-term cash requirements. We intend to fund future capital expenditures primarily through cash flows from operations and through borrowings under our revolving credit facility, but we may also issue debt or equity securities or sell additional assets. The issuance of additional debt requires a portion of our cash flows from operations be used for the payment of interest and principal on our debt, thereby reducing our ability to use cash flows to fund working capital, capital expenditures and acquisitions. The issuance of additional equity securities could have a dilutive effect on the value of our common stock.


Revolving credit facility
We have an unsecured revolving credit facility, maturing on May 16, 2019, with aggregate lender commitments totaling $2.75 billion, which may be increased up to a total of $4.0 billion upon agreement between the Company and participating lenders. The commitments are from a syndicate of 17 banks and financial institutions. We believe each member of the current syndicate has the capability to fund its commitment.
As of July 31, 2016,2017, we had approximately $1.93$1.81 billion of borrowing availability on our credit facility after considering outstanding borrowings and letters of credit. BorrowingsCredit facility borrowings bear interest at market-based interest rates plus a margin based on the terms of the borrowing and the credit ratings assigned to our senior, unsecured, long-term indebtedness.
The commitments under our revolving credit facility are not dependent on a borrowing base calculation subject to periodic redetermination based on changes in commodity prices and proved reserves. Additionally, downgrades or other


negative rating actions with respect to our credit rating such as the downgrades by Standard & Poor's Ratings Services ("S&P") and Moody's Investor Services, Inc. ("Moody's") that occurred in February 2016 in response to weakened oil and gas industry conditions, dowould not trigger a reduction in our current credit facility commitments, nor dowould such actions trigger a security requirement or change in covenants. The downgrades ofweighted-average interest rate on our credit rating did, however, trigger a 0.250% increase in our credit facility's interest ratefacility borrowings was 2.85% at June 30, 2017 and a 0.075% increase in the rate ofwe incur commitment fees paidof 0.30% per annum on the daily average amount of unused borrowing availability under our credit facility.availability.
Our revolving credit facility contains restrictive covenants that may limit our ability to, among other things, incur additional indebtedness, incur liens, engage in sale and leaseback transactions, and merge, consolidate or sell all or substantially all of our assets. Our credit facility also contains a requirement that we maintain a consolidated net debt to total capitalization ratio of no greater than 0.65 to 1.00. This ratio represents the ratio of net debt (calculated as total face value of debt plus outstanding letters of credit less cash and cash equivalents) divided by the sum of net debt plus total shareholders' equity plus, to the extent resulting in a reduction of total shareholders’ equity, the amount of any non-cash impairment charges incurred, net of any tax effect, after June 30, 2014.
We were in compliance with our revolving credit facility covenants at June 30, 20162017 and expect to maintain compliance for at least the next 12 months. At June 30, 2016,2017, our consolidated net debt to total capitalization ratio, as defined in our revolving credit facility as amended, was 0.590.56 to 1.00. As we continue to focus on balancing our 2016 capital spending with cash flows to minimize new borrowings, weWe do not believe the revolving credit facility covenants are reasonably likely to limit our ability to undertake additional debt financing to a material extent if needed to support our business. At June 30, 2016,2017, our total debt would have needed to independently increase by approximately $2.2$2.9 billion or 31%, above the existing levelslevel at that date (with no corresponding increase in cash or reduction in refinanced debt) to reach the maximum covenant ratio of 0.65 to 1.00. Alternatively, our total shareholders' equity would have needed to independently decrease by approximately $1.2$1.6 billion (excluding the after-tax impact of any non-cash impairment charges), or 27% below the existing levelslevel at June 30, 20162017 to reach the maximum covenant ratio. These independent point-in-time sensitivities do not take into account other factors that could arise to mitigate the impact of changes in debt and equity on our consolidated net debt to total capitalization ratio, such as disposing of assets or exploring alternative sources of capitalization.
Joint development agreement funding
In September 2014, we entered into an agreement with a U.S. subsidiary of SK E&S Co. Ltd ("SK") of South Korea to jointly develop a significant portion of the Company's Northwest Cana natural gasSTACK properties. Pursuant to the agreement SK will fund, or carry, 50% of our drilling and completion costs attributable to an area of mutual interest within our Northwest Cana propertiestargeting the Woodford formation in the STACK play until approximately $270 million has been expended by SK on our behalf. As of June 30, 2016,2017, approximately $175$125 million of the carry to be expended by SK on our behalf had yet to be realized and is expected to be realized through 2019.mid-2019.
Proceeds from pending sale of assets
On August 2, 2016, we entered into an agreement to sell non-strategic producing and non-producing properties in the SCOOP play in Oklahoma to a third party for cash proceeds of $281 million. The disposition is expected to close in October 2016. We expect to use the sales proceeds to reduce outstanding debt.


Future Capital Requirements
Senior notes
Our long-term debt includes outstanding senior note obligations totaling $5.8$5.2 billion at June 30, 2016.2017. We have no near-term senior note maturities, with our earliest scheduled senior note maturity being our $200 million$2.0 billion of 20202022 Notes due in October 2020.September 2022. Our senior notes are not subject to any mandatory redemption or sinking fund requirements. For further information on the face values, maturity dates, semi-annual interest payment dates, optional redemption periods and covenant restrictions related to our senior notes, refer to Note 6. Long-Term Debt in Notes to Unaudited Condensed Consolidated Financial Statements.
We were in compliance with our senior note covenants at June 30, 20162017 and expect to maintain compliance for at least the next 12 months. We do not believe the senior note covenants will materially limit our ability to undertake additional debt financing. Downgrades or other negative rating actions with respect to the credit ratings assigned to our senior unsecured debt such as the downgrades by S&P and Moody's that occurred in February 2016, dowould not trigger additional senior note covenants.
TwoThree of our subsidiaries, Banner Pipeline Company, L.L.C. and, CLR Asset Holdings, LLC, and The Mineral Resources Company, which have no material assets or operations, fully and unconditionally guarantee the senior notes on a joint and several basis. Our other subsidiaries, the value of whose assets and operations are minor, do not guarantee the senior notes as of June 30, 2016.2017.


Term loan
We have a $500 million unsecured term loan that matures in full in November 2018 and bears interest at variable market-based interest rates plus a margin based on the terms of the borrowing and the credit ratings assigned to the Company's senior, unsecured, long-term indebtedness. Downgrades or other negative rating actions with respect to our credit rating such as the S&P and Moody's downgrades that occurred in February 2016, dowould not trigger a security requirement or change in covenants for the term loan. The February 2016 downgrades of our credit rating did, however, trigger a 0.125% increase in our term loan's interest rate. The interest rate on the term loan was 1.95%2.64% at June 30, 2016.2017.
Capital expenditures
We evaluate opportunities to purchase or sell crude oil and natural gas properties and expect to participate as a buyer or seller of properties at various times. We seek acquisitions that utilize our technical expertise or offer opportunities to expand our existing core areas. Acquisition expenditures are not budgeted.
Our original capital expenditures budget for 2016 is $920 million2017 was $1.95 billion excluding acquisitions, which iswas expected to be allocated as follows:

Based on improvements in drilling efficiencies, continued volatility in commodity prices, and our strategy of managing capital spending to minimize the incurrence of new debt and maintain financial flexibility, we now expect to spend between $1.75 billion and $1.95 billion for the year.
For the six months ended June 30, 2016,2017, we invested approximately $529.3$978.9 million in our capital program, excluding $14.3$19.2 million of unbudgeted acquisitions, excluding $86.5including $108.1 million of capital costs associated with decreasedincreased accruals for capital expenditures, and including $0.1$2.8 million of seismic costs.

Our non-acquisition capital spending budget for 2016 has been set based on an expectation of available cash flowsdrilling and is designed to target capital expenditurescompletion activities and cash flows being relatively balanced for 2016 at an assumed average WTI benchmark crude oil price of approximately $37 per barrel for the year, with any cash flow deficiencies being funded by borrowings under our revolving credit facility. Over the six months ended June 30, 2016, WTI crude oil benchmark prices have averaged approximately $40 per barrel.
The actual amount and timing of our capital expenditures may differ materially from our budget as a result of, among other things, access to capital, available cash flows, unbudgeted acquisitions, actual drilling and completion results, the availability of drilling and completion rigs and other services and equipment, the availability of transportation capacity, changes in commodity prices, and regulatory, technological and competitive developments. We monitor our capital spending closely based on actual and projected cash flows and may continue to scale back our 2017 capital spending plans should commodity prices decrease from current levels. Conversely, an increase in commodity prices from current levels could result in increased capital expenditures. We expect to continue participating as a buyer of properties when and if we have the ability to increase our position in strategic plays at competitive terms.
Commitments
Refer to Note 7. Commitments and Contingencies in Notes to Unaudited Condensed Consolidated Financial Statements for a discussion of certain future commitments of the Company as of June 30, 2016.2017. We believe our cash flows from operations, our remaining cash balance, and amounts available under our revolving credit facility will be sufficient to satisfy our commitments.


Off-balance sheet arrangements
Currently, we do not have any off-balance sheet arrangements with unconsolidated entities to enhance liquidity and capital resources.

ITEM 3.Quantitative and Qualitative Disclosures About Market Risk    
General. We are exposed to a variety of market risks including commodity price risk, credit risk, and interest rate risk. We seek to address these risks through a program of risk management which may include the use of derivative instruments.
Commodity Price Risk. Our primary market risk exposure is in the prices we receive from sales of our crude oil and natural gas production. Realized pricing is primarily driven by the prevailing worldwide price for crude oil and spot market prices applicable to our natural gas production. Pricing for crude oil and natural gas has been volatile and unpredictable for several years, and we expect this volatility to continue in the future. The prices we receive for production depend on many factors outside of our control, including volatility in the differences between product prices at sales points and the applicable index prices. Based on our average daily production for the six months ended June 30, 2016,2017, and excluding any effect of our derivative instruments in place, our annual revenue would increase or decrease by approximately $510$446 million for each $10.00 per barrel change in crude oil prices at June 30, 20162017 and $187$214 million for each $1.00 per Mcf change in natural gas prices at June 30, 2016.2017.
To reduce price risk caused by market fluctuations in crude oil and natural gas prices, from time to time we may economically hedge a portion of our anticipated crude oil and natural gas production as part of our risk management program. In addition, we may utilize basis contracts to hedge the differential between derivative contract index prices and those of our physical pricing points. Reducing our exposure to price volatility helps secure funds to be used for our capital program. Our decision on the quantity and price at which we choose to hedge our production is based in part on our view of current and future market conditions. We may choose not to hedge future production if the price environment for certain time periods is deemed to be unfavorable. Additionally, we may choose to liquidate existing derivative positions prior to the expiration of their contractual maturities in order to monetize gain positions for the purpose of funding our capital program. While hedging, if utilized, limits the downside risk of adverse price movements, it also limits future revenues from upward price movements. Our crude oil production and sales for the remainder of 20162017 and beyond are currently unhedged and directly exposed to continued volatility in crude oil market prices, whether favorable or unfavorable.
Changes in natural gas prices during the six months ended June 30, 20162017 had an overall unfavorablefavorable impact on the fair value of our derivative instruments. For the six months ended June 30, 2016,2017, we recognized cash gains on natural gas derivatives of $78.0$2.7 million which were more than offset byand non-cash mark-to-market lossesgains on natural gas derivatives of $118.1$72.1 million.

The fair value of our natural gas derivative instruments at June 30, 20162017 was a net liabilityasset of $16.9$12.7 million. An assumed increase in the forward prices used in the June 30, 20162017 valuation of our natural gas derivatives of $1.00 per MMBtu would increase our natural gas derivative liability to approximately $161 million at June 30, 2016. Conversely, an assumed decrease in forward prices of $1.00 per MMBtu would change our natural gas derivative valuation to a net assetliability of approximately $120$71 million at June 30, 2016.2017. Conversely, an assumed decrease in forward prices of $1.00 per MMBtu would increase our natural gas derivative asset to approximately $91 million at June 30, 2017. Changes in the fair value of our natural gas derivatives from the above price sensitivities would produce a corresponding change in our total revenues.
Credit Risk. We monitor our risk of loss due to non-performance by counterparties of their contractual obligations. Our principal exposure to credit risk is through the sale of our crude oil and natural gas production, which we market to energy marketing companies, crude oil refining companies, and natural gas gathering and processing companies ($385386 millionin receivables at June 30, 2016),2017); our joint interest and other receivables ($261402 millionat June 30, 2016),2017); and counterparty credit risk associated with our derivative instrument receivables ($2018 million at June 30, 2016)2017).
We monitor our exposure to counterparties on crude oil and natural gas sales primarily by reviewing credit ratings, financial statements and payment history. We extend credit terms based on our evaluation of each counterparty’s credit worthiness. We have not generally required our counterparties to provide collateral to secure crude oil and natural gas sales receivables owed to us. Historically, our credit losses on crude oil and natural gas sales receivables have been immaterial.

Joint interest receivables arise from billing the individuals and entities who own a partial interest in the wells we operate. These individuals and entities participate in our wells primarily based on their ownership in leases included in units on which we wish to drill. We can do very little to choose who participates in our wells. In order to minimize our exposure to this credit risk we generally request prepayment of drilling costs where it is allowed by contract or state law. For such prepayments, a liability is recorded and subsequently reduced as the associated work is performed. This liability was $85$53 million at June 30, 2016,2017, which will be used to offset future capital costs when billed. In this manner, we reduce credit risk. We may have the right to place a lien on our co-owners interest in the well to redirect production proceeds in order to secure payment or, if necessary, foreclose on the interest. Historically, our credit losses on joint interest receivables have been immaterial.
Our use of derivative instruments involves the risk that our counterparties will be unable to meet their commitments under the arrangements. We manage this risk by using multiple counterparties who we consider to be financially strong in order to minimize our exposure to credit risk with any individual counterparty.
Interest Rate Risk. Our exposure to changes in interest rates relates primarily to any variable-rate borrowings we may have outstanding from time to time under our revolving credit facility and three-year term loan. Such borrowings bear interest at market-based interest rates plus a margin based on the terms of the borrowing and the credit ratings assigned to our senior, unsecured, long-term indebtedness. In February 2016, our corporate credit rating was downgraded by S&P and Moody's in response to weakened oil and gas industry conditions and resulting revisions made to rating agency commodity price assumptions. These downgrades caused the interest rates on our revolving credit facility borrowings and three-year term loan to increase by 0.250% and 0.125%, respectively. All of our other long-term indebtedness is fixed rate and does not expose us to the risk of cash flow loss due to changes in market interest rates.
We manage our interest rate exposure by monitoring both the effects of market changes in interest rates and the proportion of our debt portfolio that is variable-rate versus fixed-rate debt. We may utilize interest rate derivatives to alter interest rate exposure in an attempt to reduce interest rate expense related to existing debt issues. Interest rate derivatives may be used solely to modify interest rate exposure and not to modify the overall leverage of the debt portfolio. We currently have no interest rate derivatives.
We had an aggregate of $1.32$1.44 billion of variable rate borrowings outstanding on our revolving credit facility and three-year term loan at July 31, 2016.2017. The impact of a 0.25% increase in interest rates on this amount of debt would result in increased interest expense of approximately $3.3$3.6 million per year and a $2.0$2.2 million decrease in net income per year.

ITEM 4.    Controls and Procedures
Evaluation of Disclosure Controls and Procedures
As of the end of the period covered by this report, an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) was performed under the supervision and with the participation of the Company’s management, including its Chief Executive Officer and Chief Financial Officer. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded the Company’s disclosure controls and procedures were effective as of June 30, 20162017 to ensure information required to be disclosed in the reports it files and submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and information required to

be disclosed under the Exchange Act is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
Changes in Internal Control over Financial Reporting
During the three months ended June 30, 2016,2017, there were no changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Inherent Limitations on Controls and Procedures
A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Accordingly, even an effective system of internal control will provide only reasonable assurance that the objectives of the internal control system are met.
