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.
“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.
“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.
“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.
"Net crude oil and natural gas sales" Represents total crude oil and natural gas sales less total transportation expenses. Net crude oil and natural gas sales presented herein are non-GAAP measures. See Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Non-GAAP Financial Measures for a discussion and calculation of this measure.
"Net sales price" Represents the average net wellhead sales price received by the Company for its crude oil or natural gas sales after deducting transportation expenses. Amount is calculated by taking revenues less transportation expenses divided by sales volumes for a period, whether for crude oil or natural gas, as applicable. Net sales prices presented herein are non-GAAP measures. See Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Non-GAAP Financial Measures for a discussion and calculation of this measure.
“NYMEX” The New York Mercantile Exchange.

i



“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.
“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 counties 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 Woodford formations. A significant portion of our STACK acreage is located in over-pressured portions of Blaine, Dewey and Custer counties 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,” “target,” “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;
shutting in of production and the resumption of production activities;
competition;
marketing of crude oil and natural gas;
transportation of crude oil, natural gas liquids, and natural gas to markets;
property exploitation, property acquisitions and dispositions, or joint development opportunities;
costs of exploiting and developing our properties and conducting other operations;
our financial position, dividend payments, bond repurchases, or dividend payments;share repurchases;
generalthe impact of the COVID-19 (novel coronavirus) pandemic on economic conditions;conditions, the demand for crude oil, the Company's operations and the operations of its customers, suppliers, and service providers;
credit markets;
our liquidity and access to capital;
the impact of governmental policies, laws and regulations, as well as regulatory and legal proceedings involving us and of scheduled or potential regulatory or legal changes;

our future commodity or other hedging arrangements; and
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, 2018,2019, our Form 10-Q for the quarter ended March 31, 2020, registration statements we file from time to time with the Securities and Exchange Commission, and other announcements we make from time to time.
Many of the foregoing risks and uncertainties have been, and may further be, exacerbated by the COVID-19 pandemic and any consequent worsening of the global economic environment. New factors emerge from time to time, and it is not possible for us to predict all such factors. 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, or our Form 10-Q for the quarter ended March 31, 2020 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.

iii


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.

Note 2. Basis of Presentation and Significant Accounting Policies
Basis of presentation
The condensed consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, and entities in which the Company has a controlling financial interest. Intercompany accounts and transactions have been eliminated upon consolidation. Noncontrolling interests reflected herein represent third party ownership in the net assets of consolidated subsidiaries. The portions of consolidated net income (loss) and equity attributable to the noncontrolling interests are presented separately in the Company’s financial statements.
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, 20182019 (“20182019 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, 20192020 and for the three and six month periods ended June 30, 20192020 and 20182019 are unaudited. The condensed consolidated balance sheet as of December 31, 20182019 was derived from the audited balance sheet included in the 20182019 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 estimates and assumptions impacting reported results are 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 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 net income (loss) per share is computed by dividing net income (loss) attributable to the Company by the weighted-average number of shares outstanding for the period. In periods where the Company has net income, diluted earnings per share reflects the potential dilution of non-vested restricted stock awards, which are calculated using the treasury stock method. The following

(1)For the three and six months ended June 30, 2020 the Company had a net loss and therefore the potential dilutive effect of approximately 23,000 and 243,000 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.
Inventories
Inventory is comprised of crude oil held in storage or as line fill in pipelines, pipeline imbalances, 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 net realizable value primarily using the first-in, first-out inventory method. Tubular goods and equipment are valued primarily using a weighted average cost method applied to specific classes of inventory items.
The components of inventory as of June 30, 20192020 and December 31, 20182019 consisted of the following:

In the first quarter of 2020 the Company recognized a $24.5 million impairment to reduce its crude oil inventory to estimated net realizable value at March 31, 2020. The impairment is included in the caption “Property impairments” in the unaudited condensed consolidated statements of comprehensive income (loss) for the six month period ended June 30, 2020.
Adoption of new accounting pronouncement
On January 1, 20192020 the Company adopted Accounting Standards Update ("ASU") 2016-02, Leases (Topic 842). See Note 8. Leases for discussion of the adoption impact and the applicable disclosures required by the new guidance.

On January 1, 2019 the Company adopted ASU 2016-02 which resulted in the non-cash recognition of offsetting right-of-use assets and lease liabilities totaling approximately $19 million. No significant additional right-of-use assets and lease liabilities have been recognized subsequent to January 1, 2019. See Note 8. Leases for additional information.
Note 4. Revenues
Below is a discussion of the nature, timing, and presentation of revenues arising from the Company's major revenue-generating arrangements.
Operated crude oil revenues – The Company pays third parties to transport the majority of its operated crude oil production from lease locations to downstream market centers, at which time the Company's customers take title and custody of the product in exchange for prices based on the particular market where the product was delivered. Operated crude oil revenues are recognized during the month in which control transfers to the customer and it is probable the Company will collect the consideration it is entitled to receive. Crude oil sales proceeds from operated properties are generally received by the Company within one month after the month in which a sale has occurred. Operated crude oil revenues are presented separately from transportation expenses as the Company controls the operated production prior to its transfer to customers. Transportation expenses associated with the Company's operated crude oil production totaled $46.0$23.5 million and $40.2$46.0 million for the three months ended June 30, 20192020 and 2018,2019, respectively, and $87.6$73.9 million and $80.6$87.6 million for the six months ended June 30, 20192020 and 2018,2019, respectively.
Operated natural gas revenues – The Company sells the majority of its operated natural gas production to midstream customers at its lease locations based on market prices in the field where the sales occur. Under these arrangements, the midstream customers obtain control of the unprocessed gas stream at the lease location and the Company's revenues from each sale are determined using contractually agreed pricing formulas which contain multiple components, including the volume and Btu content of the natural gas sold, the midstream customer's proceeds from the sale of residue gas and natural gas liquids ("NGLs") at secondary downstream markets, and contractual pricing adjustments reflecting the midstream customer's estimated recoupment of its investment over time. Such revenues are recognized net of pricing adjustments applied by the midstream customer during the month in which control transfers to the customer at the delivery point and it is probable the Company will collect the consideration it is entitled to receive. Natural gas sales proceeds from operated properties are generally received by the Company within one month after the month in which a sale has occurred.
Under certain arrangements, in periods of significantly depressed prices for natural gas and NGLs the contractual pricing adjustments applied by the midstream customer in a particular month may exceed the consideration to be received by the Company under the arrangement, resulting in a net payment owed by the Company to the midstream customer. In these

Notes to Unaudited Condensed Consolidated Financial Statements

situations, the net amounts paid or payable by the Company are reflected as a reduction of natural gas sales in the caption "Crude oil and natural gas sales" in the unaudited condensed consolidated statements of comprehensive income (loss). Such payments, which are referred to herein as negative gas revenues, totaled $22.7 million for operated properties for the three and six months ended June 30, 2020.
Under certain arrangements, the Company has the right to take a volume of processed residue gas and/or NGLs in-kind at the tailgate of the midstream customer's processing plant in lieu of a monetary settlement for the sale of the Company's operated natural gas production. The Company currently takes certain processed residue gas volumes in kind in lieu of monetary settlement, but does not currently take NGL volumes. When the Company elects to take volumes in kind, it pays third parties to transport the processed products it took in-kind to downstream delivery points, where it then sells to customers at prices applicable to those downstream markets. In such situations, operated revenues are recognized during the month in which control transfers to the customer at the delivery point and it is probable the Company will collect the consideration it is entitled to receive. Operated sales proceeds are generally received by the Company within one month after the month in which a sale has occurred. In these scenarios, the Company's revenues include the pricing adjustments applied by the midstream processing entity according to the applicable contractual pricing formula, but exclude the transportation expenses the Company incurs to transport the processed products to downstream customers. Transportation expenses associated with these arrangements totaled $7.48.8 million and $7.0$7.4 million for the three months ended June 30, 20192020 and 2018,2019, respectively, and $14.9$18.9 million and $15.9$14.9 million for the six months ended June 30, 20192020 and 2018,2019, respectively.
Non-operated crude oil and natural gas revenues – The Company's proportionate share of production from non-operated properties is generally marketed at the discretion of the operators. For non-operated properties, the Company receives a net payment from the operator representing its proportionate share of sales proceeds which is net of costs incurred by the operator, if any. Such non-operated revenues are recognized at the net amount of proceeds to be received by the Company during the month in which production occurs and it is probable the Company will collect the consideration it is entitled to receive. Proceeds are generally received by the Company within two to three months after the month in which production occurs.
In periods of significantly depressed prices for natural gas and NGLs the costs incurred by the outside operator in a particular month may exceed the consideration to be received by the Company, resulting in a net payment owed by the Company to the outside operator. In these situations, the net amounts paid or payable by the Company are reflected as a reduction of natural gas sales in the caption "Crude oil and natural gas sales" in the unaudited condensed consolidated statements of comprehensive income (loss). Such negative gas revenues associated with non-operated properties totaled $7.8 million for the three and six months ended June 30, 2020.
Revenues from derivative instruments – See Note 5.6. Derivative Instruments for discussion of the Company's accounting for its derivative instruments.
Revenues from service operations – Revenues from the Company's crude oil and natural gas service operations consist primarily of revenues associated with water gathering, recycling, and disposal activities and the treatment and sale of crude oil reclaimed from waste products. Revenues associated with such activities, which are derived using market-based rates or rates commensurate with industry guidelines, are recognized during the month in which services are performed, the Company has an unconditional right to receive payment, and collectability is probable. Payment is generally received by the Company within one month after the month in which services are provided.

Performance obligations
The Company satisfies the performance obligations under its crude oil and natural gas sales contracts upon delivery of its production and related transfer of control to customers. Judgment may be required in determining the point in time when control transfers to customers. Upon delivery of production, the Company has a right to receive consideration from its customers in amounts determined by the sales contracts.
Continental Resources, Inc. and Subsidiaries
Notes to Unaudited Condensed Consolidated Financial Statements

All of the Company's outstanding crude oil sales contracts at June 30, 20192020 are short-term in nature with contract terms of less than one year. For such contracts, the Company has utilized the practical expedient in Accounting Standards Codification ("ASC") 606-10-50-14 exempting the Company from disclosure of the transaction price allocated to remaining performance obligations, if any, if the performance obligation is part of a contract that has an original expected duration of one year or less.
The majority of the Company's operated natural gas production is sold at lease locations to midstream customers under multi-year term contracts. For such contracts having a term greater than one year, the Company has utilized the practical expedient in ASC 606-10-50-14A which indicates an entity is not required to disclose the transaction price allocated to remaining performance obligations, if any, if variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Under the Company's sales contracts, whether for crude oil or natural gas, each unit of production delivered to a customer represents a separate performance obligation; therefore, future volumes to be delivered are wholly unsatisfied at period-end and disclosure of the transaction price allocated to remaining performance obligations is not applicable.
Contract balances
Under the Company’s crude oil and natural gas sales contracts or activities that give rise to service revenues, the Company recognizes revenue after its performance obligations have been satisfied, at which point the Company has an unconditional right to receive payment. Accordingly, the Company’s commodity sales contracts and service activities generally do not give rise to contract assets or contract liabilities under ASC Topic 606. Instead, the Company's unconditional rights to receive consideration are presented as a receivable within "ReceivablesCrude oil and natural gas sales" or "ReceivablesJoint interest and other, net"other", as applicable, in its condensed consolidated balance sheets.
Revenues from previously satisfied performance obligations
To record revenues for commodity sales, at the end of each month the Company estimates the amount of production delivered and sold to customers and the prices to be received for such sales. Differences between estimated revenues and actual amounts received for all prior months are recorded in the month payment is received from the customer and are reflected in the financial statements within the caption "Crude oil and natural gas sales". Revenues recognized during the three and six months ended June 30, 20192020 and 20182019 related to performance obligations satisfied in prior reporting periods were not material.
Note 5. Allowance for Credit Losses
In June 2016, the FASB issued ASU 2016-13, Financial InstrumentsCredit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This standard changes how entities measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The standard replaced the previously required incurred loss approach with a forward-looking expected credit loss model for accounts receivable and other financial instruments measured at amortized cost. The standard became effective for reporting periods beginning after December 15, 2019. The Company adopted the new standard on January 1, 2020 using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the effective date. The Company's cumulative effect adjustment resulted in a $0.1 million decrease in retained earnings and corresponding decrease in receivables via the recognition of an incremental allowance for credit losses at January 1, 2020.
The Company's principal exposure to credit risk is through the sale of its crude oil and natural gas production and its receivables associated with billings to joint interest owners. Accordingly, the Company classifies its receivables into two portfolio segments as depicted on the condensed consolidated balance sheets as "ReceivablesCrude oil and natural gas sales” and "ReceivablesJoint interest and other.” Presented below are applicable disclosures required by ASU 2016-13 for each portfolio segment.

Historically, the Company's credit losses on receivables have been immaterial. The Company’s aggregate allowance for credit losses totaled $2.4 million and $2.4 million at June 30, 2020 and December 31, 2019, which is reported as "Allowance for credit losses" in the condensed consolidated balance sheets. Aggregate credit loss expenses totaled $0.7 million and $0.1 million for the three months ended June 30, 2020 and 2019, respectively, and $1.5 million and $0.1 million for the six months ended June 30, 2020 and 2019, respectively, which are included in “General and administrative expenses” in the unaudited condensed consolidated statements of comprehensive income (loss).
Receivables—Crude oil and natural gas sales
The Company's crude oil and natural gas production from operated properties is generally sold to energy marketing companies, crude oil refining companies, and natural gas gathering and processing companies. The Company monitors its credit loss exposure to these counterparties primarily by reviewing credit ratings, financial statements, and payment history. Credit terms
Continental Resources, Inc. and Subsidiaries
Notes to Unaudited Condensed Consolidated Financial Statements

are extended based on an evaluation of each counterparty’s credit worthiness. The Company has not generally required its counterparties to provide collateral to secure its crude oil and natural gas sales receivables.
Receivables associated with crude oil and natural gas sales are short term in nature. Receivables from the sale of crude oil and natural gas from operated properties are generally collected within one month after the month in which a sale has occurred, while receivables associated with non-operated properties are generally collected within two to three months after the month in which production occurs.
The Company’s allowance for credit losses on crude oil and natural gas sales was negligible at both June 30, 2020 and December 31, 2019. The allowance was determined by considering a number of factors, primarily including the Company’s history of credit losses with adjustment as needed to reflect current conditions, the length of time accounts are past due, whether amounts relate to operated properties or non-operated properties, and the counterparty's ability to pay. There were no significant write-offs, recoveries, or changes in the provision for credit losses on this portfolio segment during the three and six month periods ended June 30, 2020.
Receivables—Joint interest and other
Joint interest and other receivables primarily arise from billing the individuals and entities who own a partial interest in the wells we operate. Joint interest receivables are due within 30 days and are considered delinquent after 60 days. In order to minimize our exposure to credit risk with these counterparties we generally request prepayment of drilling costs where it is allowed by contract or state law. Such prepayments are used to offset future capital costs when billed, thereby reducing the Company's credit risk. We may have the right to place a lien on a co-owner's interest in the well, to net production proceeds against amounts owed in order to secure payment or, if necessary, foreclose on the co-owner's interest.
The Company’s allowance for credit losses on joint interest receivables totaled $2.3 million and $2.4 million at June 30, 2020 and December 31, 2019, respectively. The allowance was determined by considering a number of factors, primarily including the Company’s history of credit losses with adjustment as needed to reflect current conditions, the length of time accounts are past due, the ability to recoup amounts owed through netting of production proceeds, the balance of co-owner prepayments if any, and the co-owner's ability to pay. There were no significant write-offs, recoveries, or changes in the provision for credit losses on this portfolio segment during the three and six month periods ended June 30, 2020.
Note 5.6. Derivative Instruments
Natural gas derivatives
From time to time the Company has entered into crude oil and natural gas swap and collar derivative contracts to economically hedge against the variability in cash flows associated with future sales of natural gas production. The Company recognizes its derivative instruments on the balance sheet as either assets or liabilities measured at fair value. The Company has not designated its derivatives 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) under the caption “Gain"Gain (loss) on natural gas derivatives, net”derivative instruments, net".
The Company's natural gas derivative contracts are settled based upon reported settlement prices on commodity exchanges, with crude oil derivative settlements based on NYMEX West Texas Intermediate ("WTI") pricing and natural gas derivative settlements based on NYMEX Henry Hub settlement prices.pricing. The estimated fair value of derivativesderivative contracts is based upon various factors, including commodity exchange prices, over-the-counter quotations, and, in the case of collars, volatility, the risk-free interest rate, and the time to expiration. The calculation of the fair value of collars requires the use of an option-pricing model. See Note 6.7. Fair Value Measurements.

Notes to a 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 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.Unaudited Condensed Consolidated Financial Statements

Note 6.7. 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 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.
Level 3: Unobservable inputs 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 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 summarizetable summarizes the valuation of financialderivative instruments by pricing levels that were accounted for at fair value on a recurring basis as of June 30, 2019 and2020. The Company had no outstanding derivative instruments at December 31, 2018.2019.

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.
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. Risk-adjusted probable and possible reserves may be taken into consideration when determining estimated future net cash flows and fair value when such reserves exist and are economically recoverable. Due to the unavailability of relevant comparable market data, a discounted cash flow method is used to determine the fair value of proved properties. TheSignificant unobservable inputs (Level 3) utilized in the determination of discounted cash flow method estimates future net cash flows based on the Company’s estimates ofinclude future crude oil and natural gas production, commodity prices based on commodity futures price strips adjusted for differentials, forecasted production based on decline curve analysis, estimated future operating and development costs, property ownership interests, and a risk-adjusted10% 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 atAt June 30, 2019 to calculate2020, the fair value of proved crude oilCompany's commodity price assumptions were based on forward NYMEX strip prices through year-end 2024 and natural gas properties using a discounted cash flow method.

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.
For the six months ended June 30, 2020 the Company determined the carrying amounts of certain proved properties were not recoverable from future cash flows and therefore were impaired. Such impairments, all of which were recognized in the 2020 first quarter, totaled $181.0 million which reflect fair value adjustments on legacy properties in the Red River Units ($166.5 million) and various non-core properties in the North and South regions ($14.5 million). The impaired properties were written down to their estimated fair value at the time of impairment of $145.6 million. Impairments for the six months ended June 30, 2020 also include a $24.5 million impairment recognized in the 2020 first quarter to reduce the Company's crude oil inventory to estimated net realizable value at the time of impairment. No proved property impairments were recognized during the three months ended June 30, 2020.
For the three and six months ended June 30, 2019, and 2018, 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 thosethe 2019 periods.

The fair value of credit facility borrowings approximate carrying value based on borrowing rates available to the noteCompany for bank loans with similar terms and maturities and are classified as Level 2 in the fair value hierarchy.
The fair value of notes payable is determined using a discounted cash flow approach based on the interest rate and payment terms of the notenotes payable and an assumed discount rate. The fair value of the notenotes payable is significantly influenced by the discount rate assumption, which is derived by the Company and is unobservable. Accordingly, the fair value of the notenotes payable is classified as Level 3 in the fair value hierarchy. See Note 8. Long-Term Debt for discussion of the changes in the Company's notes payable in June 2020.
The fair values of the 5% Senior Notes due 2022 (“2022 Notes”), the 4.5% Senior Notes due 2023 (“2023 Notes”), the 3.8% Senior Notes due 2024 (“2024 Notes”), the 4.375% Senior Notes due 2028 (“2028 Notes”), and the 4.9% Senior Notes due 2044 (“2044 Notes”) are based on quoted market prices and, accordingly, are classified as Level 1 in the fair value hierarchy.
The carrying values of all classes of cash and cash equivalents, trade receivables, and trade payables are considered to be representative of their respective fair values due to the short term maturities of those instruments.

Borrowings under the creditCredit facility if any,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, 2020 was 2.1%.
The Company had approximately $908 million of borrowing availability on its credit facility at June 30, 2020 after considering outstanding borrowings and letters of credit. The Company incurs commitment fees based on currently assigned credit ratings of 0.20%0.25% per annum on the daily average amount of unused borrowing availability.
The 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. The Company was in compliance with the credit facility covenants at June 30, 2019.2020.

ITEM 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis should be read in conjunction with the unaudited condensed consolidated financial statements and notes thereto included elsewhere in this report and our historical consolidated financial statements and notes included in our Form 10-K for the year ended December 31, 2018. Our operating results for the periods discussed below may not be indicative of future performance. 2019.
The following discussion and analysis includes forward-looking statements and should be read in conjunction with the risk factors described in Part II, Item 1A. Risk Factors included in this report, if any, and in our Form 10-K for the year ended December 31, 2018,2019 and our Form 10-Q for the quarter ended March 31, 2020, along with Cautionary Statement for the Purpose of the “Safe Harbor” Provisions of the Private Securities Litigation Reform Act of 1995 at the beginning of this report, for information about the risks and uncertainties that could cause our actual results to be materially different than our forward-looking statements.
Our operating results for the 2020 second quarter discussed below were significantly impacted by the economic effects from the COVID-19 pandemic on crude oil demand and prices and may not be indicative of future results for the remainder of 2020. Crude oil prices have improved from historic lows in April 2020 and we have begun to restore a portion of our voluntary production curtailments initiated in the second quarter as discussed below. Accordingly, although our performance and ability to execute our business strategies continue to be impacted by the effects of COVID-19, our operating and financial results for the remainder of 2020 are expected to improve relative to the 2020 second quarter if current prices for crude oil, natural gas, and natural gas liquids are sustained or improve.
Overview
We are an independent crude oil and natural gas company engaged in the exploration, development and production of crude oil and natural gas. Additionally, we pursue the acquisition and management of perpetually owned minerals located in certain of our key operating areas. 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 and STACK areas of Oklahoma. Our common stock trades on the New York Stock Exchange under the symbol “CLR” and our corporate internet website is www.clr.com.
Second Quarter 2019 HighlightsBusiness Environment and Outlook
Initiated a total shareholder return strategy that includes a share repurchase programCrude oil prices decreased to historically low levels in April 2020 due to reduced global and domestic demand for crude oil caused by the impact of upthe COVID-19 pandemic and resulting changes in consumer behavior and restrictions implemented by governments to $1 billion beginningmitigate the pandemic. The economic turmoil resulting from COVID-19 resulted in June 2019material decreases in our production, revenues, and a quarterly dividend of $0.05 per share on our common stock.  
Total production forcash flows in the second quarter of 2019 averaged 331,4142020. In response to the significant reduction in crude oil prices, we voluntarily curtailed approximately 55% of our operated crude oil production and associated natural gas in the 2020 second quarter to preserve shareholder value. Additionally, we implemented cost saving initiatives and significantly reduced our operated rig and completion crew counts in order to preserve our assets and better align our capital spending with expected available cash flows.
As a result of these actions, our total production declined to 202,815 Boe per day an increasefor the 2020 second quarter, a decrease of 17%44% compared to the first quarter of 2020 and 39% lower than the second quarter of 2018.
Crude oil production increased 23% over the 2018 second quarter driven by strong production growth in the Bakken field and Project SpringBoard play in SCOOP.
Bakken and SCOOP crude oil production increased 22% and 48%, respectively, over the 2018 second quarter.
Reduced2019. Further, we reduced our non-acquisition capital spending by $61.4$460 million, or 8%71%, in the 20192020 second quarter compared to the 20192020 first quarter, while achieving year-over-yearquarter.
Crude oil prices have shown signs of stabilization and improvement in June and July in response to the gradual lifting of restrictions and resumption of economic activity and ongoing restoration of crude oil demand, with West Texas Intermediate crude oil benchmark prices averaging approximately $40 per barrel in July 2020. As a result, in July we began to partially restore our curtailed production and plan to continue restoring production as improved supply and demand fundamentals continue to benefit oil prices. Accordingly, we expect to see production growth objectives.in the second half of the year relative to 2020 second quarter levels. Our production volumes are evaluated on an ongoing basis and are subject to change as market conditions evolve.
Debt reduction overWe continue to actively evaluate the past year generated a $13.9 million, or 9%, decrease in interest expense for year to date 2019 comparedimpact of COVID-19 on our operations, financial condition, suppliers, industry, and workforce. We are committed to the comparable 2018 period.responsible stewardship of our assets and, in light of economic uncertainty from the pandemic, we will continue to preserve shareholder value and focus on protecting the strength of our balance sheet, preserving financial flexibility and liquidity, delivering capital efficient operations and cost savings, and conserving the development of our assets.
Our leadership team has significant experience with operating in challenging commodity price environments. The depth and quality of our asset base, the optionality provided by our predominant amount of acreage held by production, and our financial


strength allow us to be adaptable in a variety of price environments. We will remain flexible as we monitor and adapt to market conditions. See the subsequent section titled Liquidity and Capital Resources for additional discussion of our financial condition.

The 23% increase51% decrease in crude oil production for the 20192020 second quarter was primarily driven by the previously described production curtailments implemented during the quarter coupled with minimal drilling and completion activities, which led to a 2,4547,802 MBbls, or 58%, decrease in Bakken crude oil production, a526 MBbls, or 22%, increasedecrease in Bakken production due to additional wells being completed. Additionally,SCOOP crude oil production, from the SCOOP play increased 786and a 509 MBbls, or 48%59%, decrease in STACK crude oil production.
Our production curtailments and minimal drilling and completion activities also impacted our natural gas production, leading to a 22% decrease in natural gas production for the 2020 second quarter compared to the 2019 second quarter. Natural gas production in the Bakken decreased 10,626 MMcf, or 43%, and natural gas production in STACK decreased 9,205 MMcf, or 35%, from the prior year second quarter due to new well completions in our oil-weighted Project SpringBoard, while crude oil production in the STACK play increased 99 MBbls, or 12%, from new well completions.quarter. These increasesdecreases were partially offset by decreased crude oil production from various other areas due to natural declines in production.
The 9% increase in natural gas production for the 2019 second quarter was driven by a 4,8743,607 MMcf, or 25%15%, increase in Bakken gas production in conjunction with the aforementioned increase in Bakken crude oil production over the prior year second quarter. Additionally,SCOOP natural gas production in the STACK play increased 2,401 MMcf, or 10%, due to additional wells being completed. These increases were partially offset by reduced production from various other areas due to natural declines in production.
Revenues
Our revenues consist of sales of crude oil and natural gas, gains and losses resulting from changes in the fair value of our natural gas derivative instruments, and revenues associated with crude oil and natural gas service operations.
Net crude oil and natural gas sales and related net sales prices presented below are non-GAAP measures. See the subsequent section titled Non-GAAP Financial Measures for a discussion and calculation of these measures.
Net crude oil and natural gas sales. Net crude oil and natural gas sales totaled $1.08 billion$142.3 million for the second quarter of 2019,2020, an consistent with87% decrease compared to net sales of $1.09$1.08 billion for the 20182019 second quarterdue to offsetting changessignificant decreases in sales volumes and net sales prices and sales volumes as discussed below.
Total sales volumes for the second quarter of 2019 increased 4,2282020 decreased 12,026 MBoe, or 16%40%, compared to the 20182019 second quarter,reflecting an increasereduced sales from the previously described production curtailments in drilling and completion activities over the past year.current period. For the second quarter of 2019,2020, our crude oil sales volumes increased 23%decreased 53% from the comparable 20182019 period, while our natural gas sales volumes increased 9%decreased 22%.
Our crude oil net sales prices averaged $54.66$16.35 per barrel in the 20192020 second quarter, a decrease of 14%70% compared to $63.35$54.66 per barrel for the 20182019 second quarter primarily due to lower crude oilsignificantly reduced market prices.prices and wider price differentials. The differential between NYMEX West Texas Intermediate ("WTI") calendar month prices and our realized crude oil net sales prices averaged $7.54 per barrel for the 2020 second quarter compared to $5.11 per barrel for the 2019 second quarter compared to $4.55 per barrel for the 2018 second quarter, reflectingquarter. The increased differential reflects changes in supply and demand fundamentals over the past yearand economic effects from COVID-19 that created volatility in ourimpacted location differentials and price realizations between periods.compared to the prior year period.
See the subsequent section titled Future Capital Requirements–Commitments and contingenciesfor discussion of recent developments that may impact the operation of the Dakota Access Pipeline ("DAPL") owned by a third party that we and other operators utilize to transport Bakken crude oil production to market centers outside the basin. The restriction of DAPL's takeaway capacity may have an impact on prices for Bakken-produced barrels and result in wider differentials relative to WTI benchmark prices in the future, the amount of which is uncertain. If transportation capacity on DAPL becomes restricted or unavailable, we have the ability to utilize other third party pipelines or rail facilities to transport our Bakken crude oil production to market, although such alternatives may be more costly.
Our natural gas net sales prices averaged $0.12 per Mcf for the 2020 second quarter, a decrease of 93% compared to $1.66 per Mcf for the 2019 second quarter a decrease of 37% compareddue to $2.65 per Mcf for the 2018 second quarter.significantly reduced market prices and lower price realizations. The discount between our net sales prices and NYMEX Henry Hub calendar month natural gas prices weakened by $0.83to $1.58 per Mcf for the 2020 second quarter compared to $0.98 per Mcf for the 20182019 second quarter. We sell the majority of our operated natural gas production to


midstream customers at lease locations based on market prices in the field where the sales occur. The field markets are impacted by residue gas and natural gas liquids ("NGLs") prices at secondary, downstream markets. NGL prices in 20192020 have decreased significantly compared to 2018 second quarter2019 levels in conjunction with decreased crude oil prices and other factors, resulting in reduced price realizations for our natural gas sales stream relative to benchmark prices. As a result of the significant decrease in prices, under certain of our arrangements on operated properties the contractual pricing adjustments applied by midstream customers exceeded the sales consideration we were entitled to receive, resulting in a net payment owed by us to the customers. Additionally, in some instances on non-operated properties the costs incurred by the outside operator exceeded the consideration we were entitled to receive, resulting in a net payment owed by us to the outside operator. The net amounts paid or payable under these arrangements on operated and non-operated properties totaled $30.5 million for the 2020 second quarter, with immaterial amounts in prior periods, and are reflected as a reduction of natural gas revenues and net sales prices. Nearly all of such amounts are associated with our North region natural gas production.
NGL prices have improved from recent lows in conjunction with increased crude oil prices and other factors, which has resulted in improved price realizations for our natural gas sales stream. If prices remain at current levels or improve, while we may recognize additional negative gas revenues in the second half of 2020, we would not expect such amounts to be of a similar magnitude as the negative gas revenues recognized in the 2020 second quarter.
Derivatives. Changes in natural gas marketcrude oil prices during the second quarter of 20192020 had a favorablean overall unfavorable impact on the fair value of our natural gas derivatives, which resulted in negative revenue adjustments of $7.8 million for the period compared to positive revenue adjustments of $53.4 million in the current period compared to negative revenue adjustments of $12.7 million in the comparable 20182019 period.
Crude oil and natural gas service operationsoperations. . Revenues associated with ourOur crude oil and natural gas service operations increased $5.2consist primarily of revenues associated with water gathering, recycling, and disposal activities and the treatment and sale of crude oil reclaimed from waste products. Revenues associated with such activities decreased $8.7 million, or 43%50%, from $12.3 million for the 2018 second quarter to $17.5 million for the 2019 second quarter of 2019 to $8.8 million for the second quarter of 2020 due to an increasea decrease in the magnitude of water handling and recycling activities compared toresulting from our curtailment of production activities during the prior period.current quarter. The increaseddecreased activities also resulted in highera reduction in service-related expenses compared to the prior period.
Operating Costs and Expenses
Production Expenses. Production expenses increased $22.2decreased $47.7 million, or 25%42%, from $90.2$112.4 million for the second quarter of 20182019 to $112.4$64.7 million for the second quarter of 2020 due to the previously described production curtailments and associated 40% decrease in sales volumes. Production expenses on a per-Boe basis averaged $3.58 for the 2020 second quarter, improved from $3.74 per Boe recognized for the 2019 second quarter. We expect our total production expenses to increase in the second half of 2020 relative to second quarter levels as we begin to resume production on curtailed wells, the amount of which is uncertain.
Production Taxes. Production taxes decreased $82.8 million, or 88%, to $11.1 million for the second quarter of 2020 compared to $93.9 million for the second quarter of 2019 primarily due to an increase85% decrease in the number of producing wells and related 16% increase in sales volumes. Production expenses on a per-Boe basis averaged $3.74 for the 2019 second quarter compared to $3.49 per Boe recognized for the 2018 second quarter.
Production Taxes. Production taxes increased $10.3 million, or 12%, to $93.9 million for the second quarter of 2019 compared to $83.6 million for the second quarter of 2018, despite flat revenues, due in part to an increase in the proportion of our production and revenues being generated in North Dakota over the past year from increased oil-weighted drilling and completion activities. North Dakota has higher crude oil production tax rates compared to Oklahoma. Additionally, production


taxes forand natural gas revenues in North Dakota are based on a per-unit rate applied to the quantity of volumes sold whereas in Oklahoma such production taxes are based on a percentage applied to the wellhead value of sales. These factors caused ourOur production taxes as a percentage of net crude oil and natural gas sales to increasedecreased from 7.7% for the second quarter of 2018 to 8.7% for the second quarter of 2019. Additionally,2019 to 7.8% for the second quarter of 2020 primarily resulting from an increase in March 2018 new legislation was enactedthe proportion of our revenues being generated in Oklahoma that increasedin the state'scurrent period, which has lower production tax rate, effective July 1, 2018, from 2% to 5% for the first 36 months of production for wells commencing production after July 1, 2015, which also contributed to the increase in our average production tax raterates compared to the prior year second quarter.North Dakota.

For the second quarters of 20192020 and 20182019 we provided for income taxes at a combined federal and state tax rate of 24.5% and 24.0%, respectively, of pre-tax incomeincome/loss generated by our operations in the United States. We recorded an income tax provisionsbenefit of $72.1 million for the 2020 second quarter and an income tax provision of $75.6 million and $75.2 million for the 2019 second quarters of 2019 and 2018, respectively,quarter, which resulted in effective tax rates of 24.2%23.0% and 23.7%24.2%, respectively, after taking into account statutory tax rates, permanent taxable differences, tax effects from equity compensation, valuation allowances, and other items.

The 21% increase23% decrease in crude oil production for year to date 20192020 was primarily driven by a 4,973an 8,530 MBbls, or 22%31%, decrease in Bakken oil production along with a 589 MBbls, or 36%, decrease in STACK oil production due to the previously described production curtailments and minimal drilling and completion activities undertaken during the 2020 second quarter. These decreases were partially offset by a 1,146 MBbls, or 26%, increase in Bakken production due to additional wells being completed. Additionally, crude oil production from thein SCOOP play increased 1,331 MBbls, or 43%, from the prior year period due to new well completions over the past year in our oil-weighted Project SpringBoard. These increases were partially offset by decreased crude oilSpringBoard, which exceeded the adverse impact of production from various other areas duecurtailments in the play in the 2020 second quarter.
Our production curtailments and minimal drilling and completion activities in the 2020 second quarter also impacted our year to natural declines in production.
The 10% increase indate natural gas production, forleading to a 15,128 MMcf, or 29%, decrease in STACK gas production and a 3,920 MMcf, or 8%, decrease in Bakken gas production over the prior year to date 2019 was primarily drivenperiod. These decreases were nearly offset by a 10,31915,909 MMcf, or 27%33%, increase in BakkenSCOOP gas production in conjunction with the aforementionedpreviously described increase in Bakken crudeSCOOP oil production over the prior year period. Additionally, natural gas production in the STACK play increased 5,671 MMcf, or 12%, due to additional wells being completed. These increases were partially offset by reduced production from various other areas due to natural declines in production.


Revenues
Net crude oil and natural gas sales. Net crude oil and natural gas sales for year to date 20192020 totaled $2.14 billion, consistent with$944.6 million, a decrease of 56% compared to net sales of $2.15$2.14 billion for the comparable 20182019 period due to offsetting changessignificant decreases in sales volumes and net sales prices and sales volumes as discussed below.
Total sales volumes for year to date 2019 increased 8,2452020 decreased 9,021 MBoe, or 16%15%, compared to year to date 2018,2019, reflecting an increasereduced sales from the previously described production curtailments in drilling and completion activities over the past year.current period. For year to date 2019,2020, our crude oil sales volumes increased 20%decreased 24% from the comparable 20182019 period, while our natural gas sales volumes increased 10%decreased 2%.
Our crude oil net sales prices averaged $32.37 per barrel for year to date 2020, a decrease of 38% compared to $52.36 per barrel for year to date 2019 a decrease of 14% compared to $61.14 per barrel for year to date 2018 primarily due to lower crude oilsignificantly reduced market prices.prices and wider price differentials. The differential between NYMEX WTI calendar month prices and our realized crude oil net sales prices averaged $6.66 per barrel for year to date 2020 compared to $4.94 per barrel for year to date 2019 compared to $4.22 per barrel for year to date 2018, reflecting2019. The increased differential reflects changes in supply and demand fundamentals over the past yearand economic effects from COVID-19 that created volatility in ourimpacted location differentials and price realizations between periods.compared to the prior year period.
Our natural gas net sales prices averaged $0.59 per Mcf for year to date 2020, a decrease of 72% compared to $2.11 per Mcf for year to date 2019 a decrease of 25% compareddue to $2.81 per Mcf for year to date 2018.significantly reduced market prices and lower price realizations. The discount between our net sales prices and NYMEX Henry Hub calendar month prices weakened by $0.71to $1.26 per Mcf for year to date 2020 compared to $0.79 per Mcf for the year to date 20182019 period. As discussed above, NGL prices have decreased significantly over prior year levels in conjunction with decreased crude oil prices and other factors, resulting in reduced price realizations in 20192020 for our natural gas sales stream relative to benchmark prices.prices and leading to the previously described recognition of $30.5 million of negative gas revenues in the 2020 second quarter.
Derivatives. Changes in natural gascrude oil market prices during the six months ended June 30, 20192020 had a favorablean overall unfavorable impact on the fair value of our natural gas derivatives, which resulted in negative revenue adjustments of $7.8 million for the period compared to positive revenue adjustments of $52.3 million for the period compared to negative revenue adjustments of $2.5 million in the comparable 20182019 period.
Crude oil and natural gas service operations. Revenues associated with our crude oil and natural gas service operations increased $4.0decreased $6.5 million, or 14%19%, from $29.3 million for year to date 2018 to $33.3 million for year to date 2019 to $26.8 million for year to date 2020 due to an increasea

The increaseddecreased activities also resulted in highera reduction in service-related expenses compared to the prior period.
Operating Costs and Expenses
Production Expenses. Production expenses increased $36.3decreased $36.2 million, or 20%17%, from $183.1 million for year to date 2018 to $219.4 million for year to date 2019 primarilyto $183.2 million for year to date 2020 due to an increase in the number of producing wellspreviously described production curtailments and related 16% increaseassociated 15% decrease in sales volumes. Production expenses on a per-Boe basis averaged $3.66$3.60 for year to date 2019 compared to $3.542020, improved from $3.66 per Boe recognized for the comparable 20182019 period.
Production Taxes. Production taxes increased $16.1decreased $98.0 million, or 10%54%, to $82.3 million for year to date 2020 compared to $180.3 million for year to date 2019 compared to $164.2 million for year to date 2018, despite flat revenues, due to the aforementioned increasea 54% decrease in proportion of our productioncrude oil and revenues being generated in North Dakota over the past year, which has a per-unit natural gas production tax rate assessed on volumes sold and a higher crude oil production tax rate compared to Oklahoma, and the legislation enacted in Oklahoma in 2018 as discussed above that increased the production tax rate on certain producing wells. As a result of these factors, oursales. Our production taxes as a percentage of net crude oil and natural gas sales increased from 7.6%averaged 8.7% for year to date 20182020 compared to 8.4% for year to date 2019.
Exploration expenses. Exploration expenses, which consist primarily of exploratory geological and geophysical costs and dry hole costs that are expensed as incurred, increased $8.7 million to $13.6 million for year to date 2020 compared to $4.9 million for year to date 2019 due to changes in the timing and extent of our exploration-related activities compared to the prior year period. The 2020 period includes $6.3 million of dry hole costs recognized in the first quarter associated with an unsuccessful exploratory well with no comparable dry hole costs incurred in the prior year period.

Property Impairments. Property impairments increased $199.8 million to $246.5 million for the year to date period of 2020 compared to $46.7 million for the year to date period of 2019 primarily reflecting higher proved property impairments as described below.
Impairments of proved oil and gas properties totaled $181.0 million for the year to date period of 2020, all of which were recognized in the 2020 first quarter resulting from the significant decrease in commodity prices that indicated the carrying values for certain fields were not recoverable. The impairments were recognized on legacy properties in the Red River Units ($166.5 million) and various non-core properties in the North and South regions ($14.5 million). Additionally, in response to decreased crude oil prices we recognized a $24.5 million impairment in the 2020 first quarter to reduce the value of our crude oil inventory to estimated net realizable value. There were no proved property impairments recognized during the year to date periodsperiod of 2019 and 2018. 2019.

Liquidity and Capital Resources
Our primary sources of liquidity have historically been cash flows generated from operating activities, financing provided by our credit facility and the issuance of debt securities. Additionally, in recent years asset dispositions and joint development arrangements have provided a source of cash flow for use in reducing debt and enhancing liquidity. We intendIn light of the challenges facing our business and industry, we will remain committed to continue reducingoperating in a responsible manner to preserve financial flexibility, liquidity, and the strength of our long-term debt using available cash flows from operations and/or proceeds from additional potential salesbalance sheet.

At July 31, 2020, we had approximately $848 million of assets or through joint development arrangements; however,borrowing availability under our credit facility after considering outstanding borrowings and letters of credit. Our credit facility, which is unsecured and has no assurance can be given that such transactions will occur.borrowing base subject to redetermination, does not mature until April 2023. Further, we have no near-term senior note maturities, with our earliest scheduled maturity being our $1.1 billion of 2022 Notes due in September 2022. 
Based on our planned capital spending, our forecasted cash flows and projected levels of indebtedness, we expect to maintain compliance with the covenants under our credit facility and senior note indentures for at least the next 12 months.indentures. Further, based on current market indications, we expect to meet in the ordinary course of business other contractual cash commitments to third parties as of June 30, 2019,2020, including those described in Note 9.10. 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 if needed to preserve liquidity and financial flexibility if needed to fund our operations.    
Cash Flows
Cash flows provided byfrom operating activities
Net cash provided by operating activities totaled $1.50 billion$643.6 million and $1.64$1.50 billion for the six months ended June 30, 2020 and 2019, and 2018, respectively. Therespectively, reflecting a significant decrease in operatingour 2020 second quarter cash flows was primarily due to the aforementionedpreviously described decrease in crude oil prices and natural gas commodity prices, increase inour voluntary curtailment of production expenses, and increase in production taxes. The reducedduring the quarter. As a result of these factors, we generated negative operating cash flows from these factors were partially offset by lower interest expenses and higher cash gains on matured natural gas derivativesof $20.2 million in the 2020 second quarter compared to $663.8 million of positive operating cash flows in the 2018 period.2020 first quarter.



WTI crude oil prices have improved from historic lows reached in April 2020 and averaged approximately $40 per barrel in July 2020. If crude oil prices remain at current levels or further improve and we continue to restore our curtailed production, our operating cash flows are expected to improve in the second half of 2020 relative to second quarter levels, the amount of which cannot be estimated.
Cash flows used infrom investing activities
Net cash used in investing activities totaled $1.56$1.02 billion and $1.34$1.56 billion for the six months ended June 30, 2020 and 2019, respectively, reflecting the significant decrease in our drilling and 2018, respectively. The increasecompletion activities prompted by the decrease in spending resultedcrude oil prices and economic uncertainty from changesthe COVID-19 pandemic. As a result of our reduced activities, our investing cash outflows decreased significantly from $706.7 million in the timing of our annual capital spending between periods. Our capital expenditures budget for full year 2019 is $2.6 billion compared2020 first quarter to $2.8 billion spent$312.2 million in 2018.the 2020 second quarter.
Cash flows used infrom financing activities
Net cash provided by financing activities for the six months ended June 30, 2020 totaled $342.6 million, comprised of $521.1 million of net financing cash inflows for the 2020 first quarter partially offset by $178.5 million in net financing cash outflows for the 2020 second quarter, the change of which was primarily driven by credit facility borrowing and repayment activities. Net credit facility borrowings totaled $532 million for year to date 2020, representing net borrowings of $680 million in the first quarter offset by subsequent net repayments of $148 million in the second quarter. These net credit facility borrowings for year to date 2020 were partially offset by $126.9 million of cash used to repurchase shares of our common stock, $18.5 million of cash dividends paid on common stock, and $74.0 million of cash used to repurchase senior notes in open market transactions.
Net cash used in financing activities for the six months ended June 30, 2019 totaled $23.5 million, which primarily represents $69.7 million of cash used to repurchase shares of our common stock under our share repurchase program initiated in June 2019 and $21.2 million of cash paid to taxing authorities to satisfy tax withholdings associated with restricted stock awards that vested during the period, partially offset by $75.7 million of cash inflows for contributions received from Franco-Nevada Corporation for the funding of its share of mineral acquisition costs incurred by The Mineral Resources Company II, LLC as described below under the heading "Mineral acquisition relationship."
Net cash used in financing activities for the six months ended June 30, 2018 totaled $210.3 million primarily resulting from $188 million of net repayments on our credit facility during the period.II.
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 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, dividend payments, share repurchases, and commitments for at least the next 12 months.    
UnderOur capital spending plans for the currentremainder of 2020 have been adjusted to be reflective of the adverse commodity price environment and will be guided by our planned capital expenditures for 2019expectation of available cash flows. Any cash flow deficiencies are expected to be funded entirely from operating cash flows. Additionally, we expect to generate cash flows in excess of operating and capital needs, which we plan to apply toward dividend payments, share repurchases, and further reduction of debt in the future.
We currently anticipate we will be able to generate or obtain funds sufficient to meetby borrowings under our short-term and long-term cash requirements.credit facility. 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 credit facility if needed to fund our operations and business plans. We may choose to access thebanking or capital markets for additional financing or capital to fund our operations or take advantage of business opportunities that may arise.arise, although uncertainties existing in the financial markets as a result of the COVID-19 pandemic may increase the expense and difficulty of completing a bank or capital markets financing. Additionally, the terms available to the Company in connection with such a financing transaction may be less favorable than those enjoyed by the Company prior to the COVID-19 pandemic, although the degree, if any, by which such terms may change cannot be predicted at this time. Further, we may sell assets or enter into strategic joint development opportunities in order to obtain funding if such transactions can be executed on satisfactory terms. However, no assurance can be given that such transactions will occur.

In March 2020, our corporate credit rating was downgraded by Standard & Poor's Ratings Services ("S&P") in response to weakened oil and gas industry conditions and resulting revisions made to rating agency commodity price assumptions. Such downgrade negatively impacted our cost of capital and increased our borrowing costs under our credit facility. Also in March 2020, our corporate credit ratings were reaffirmed by both Moody's Investor Services and Fitch Ratings. Such ratings are subject to ongoing review and adjustment.
Credit facility
We have an unsecured credit facility, maturing in April 2023, with aggregate lender commitments totaling $1.5 billion. The commitments are from a syndicate of 14 banks and financial institutions. We believe each member of the current syndicate has the capability to fund its commitment.
As of July 31, 20192020, we had no$647 million of outstanding borrowings and approximately $1.5 billion$848 million of borrowing availability on our credit facility.


The commitments under our 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, wouldsuch as the downgrade by S&P that occurred in March 2020 in response to weakened oil and gas industry conditions, do not trigger a reduction in our current credit facility commitments, nor woulddo such actions trigger a security requirement or change in covenants. DowngradesThe downgrade of our credit rating will,did, however, trigger increasesa 0.25% increase in our credit facility’sfacility's interest ratesrate and prompted a 0.05% increase in the rate of commitment fees paid on unused borrowing availability under certain circumstances.availability.
Our 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, or 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. See Notes to Unaudited Condensed Consolidated Financial Statements–Note 7.8. Long Term Debt for a discussion of how this ratio is calculated pursuant to our revolving credit agreement.
We were in compliance with our credit facility covenants at June 30, 20192020 and expect to maintain compliance for at least the next 12 months.such compliance. At June 30, 2019,2020, our consolidated net debt to total capitalization ratio was 0.420.43 to 1.00. We do not believe the 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.


Asset disposition proceeds
On July 18, 2019 we sold certain water gathering, recycling, At June 30, 2020, our total debt would have needed to independently increase by approximately $8.4 billion above the existing level 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 $4.5 billion (excluding the after-tax impact of any non-cash impairment charges) below the existing level at June 30, 2020 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 disposalequity on our consolidated net debt to total capitalization ratio, such as disposing of assets in the STACK play for proceedsor exploring alternative sources of $85.3 million which will be used for general corporate purposes. The disposed assets represented an immaterial portion of the Company’s assets and operating results.capitalization.
Future Capital Requirements
Senior notes
Our debt includes outstanding senior note obligations totaling $5.8$5.16 billion at June 30, 2019.2020. We have no near-term senior note maturities, with our earliest scheduled maturity being our $1.1 billion of 2022 Notes due in 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 7.8. Long-Term Debt in Notes to Unaudited Condensed Consolidated Financial Statements.
In 2018, we redeemed $400 million of our $2.0 billion of 5% Senior Notes due 2022. We plan to further redeem our 2022 Notes in the future prior to their maturity.
We were in compliance with our senior note covenants at June 30, 20192020 and expect to maintain compliance for at least the next 12 months.such compliance. 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, wouldsuch as the downgrade by S&P that occurred in March 2020, do not trigger additional senior note covenants.
Mineral acquisition relationship
In October 2018, Continental entered into a strategic relationship with Franco-Nevada Corporation to acquire oil and gas mineral interests within an area of mutual interest in the SCOOP and STACK plays through a minerals subsidiary named The Mineral Resources Company II, LLC ("TMRC II"). Under the relationship, the parties have committed, subject to satisfaction of agreed upon acreage development thresholds, to spend a remaining aggregate total of approximately $213$154 million through year-end 2021 to acquire mineral interests. Continental is to fund 20% of future mineral acquisitions and will be entitled to receive between 25% and 50% of total revenues generated by TMRC II based upon performance relative to predetermined production targets, while Franco-Nevada will fund 80% of future acquisitions and will be entitled to receive between 50% and 75% of TMRC II's revenues. Based upon production targets achieved to date, Continental is currently earning 50% of TMRC II's revenues and such allocation willis expected to continue forthrough at least year-end 2020. The timing and amount of future mineral acquisitions and resulting achievement of production targets are expected to be adversely impacted by Continental's previously described reduction in 2020 capital spending, which may impact the remainderallocation of 2019.revenues between Continental and Franco-Nevada in periods beyond 2020, the extent of which cannot be estimated.
Capital expenditures
We remain committed to operating in a disciplined, capital-efficient manner in light of ongoing economic uncertainty and volatility in commodity prices. Our original capital expenditures budget for 2019 is $2.62020 was $2.65 billion, which is expectedwas reduced to be allocated as reflected below. Acquisition expenditures are not budgeted, with$1.2 billion in March 2020 in response to the exceptionsignificant decrease in crude oil prices resulting from the COVID-19 pandemic and actions by

To capitalize on favorable market conditions, in July 2019 the Company and Franco-Nevada agreed to increase the planned spending to $150 million for 2019. With a carry structure in place, Continental will recoup 80% of such spending from Franco-Nevada.

In light of the challenges facing our business and industry we significantly reduced our drilling and completion activities beginning in March 2020 in order to preserve our assets and better align our spending with expected available cash flows. As a result of these actions, our non-acquisition capital spending was reduced by $460 million, or 71%, in the 2020 second quarter compared to the 2020 first quarter. Our 20192020 year to date capital expenditures were allocated as shown in the table below.

Our drilling and completion activities and the actual amount and timing of our capital expenditures may differ materially from our budget as a result of, among other things, available cash flows, unbudgeted acquisitions, actual drilling and completion results, operational process improvements, the availability of drilling and completion rigs and other services and equipment, the availability of transportation, gathering and processing 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 scale back our spending 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 and contingencies
Refer to Note 9.10. Commitments and Contingenciesin Notes to Unaudited Condensed Consolidated Financial Statements for discussion of certain future commitments and contingencies of the CompanyCompany. Based on current market indications, we expect to meet in the ordinary course of business our contractual cash commitments to third parties as of June 30, 2019. We believe2020.
On July 6, 2020, the U.S. District Court for the District of Columbia ruled that the Dakota Access Pipeline (“DAPL”), which is owned and operated by a third party and carries Bakken-produced crude oil from North Dakota to Illinois, must shut down pending the completion of a new environmental impact statement. The pipeline owner sought an emergency stay of the shut-down order from the U.S. Court of Appeals for the District of Columbia Circuit (the "Appeals Court"). On July 14, 2020, the Appeals Court issued a temporary administrative stay of such order, which has allowed the pipeline to continue operating as of the date of this filing. The continued operation of DAPL in the future is uncertain. The Company utilizes DAPL to transport a portion of its North region crude oil production to ultimate markets on the U.S. gulf coast. Currently, the Company is committed to transport 3,550 barrels per day on the pipeline through February 2026 and has an additional commitment to transport an incremental 26,450 barrels per day for 7 years effective upon the pending completion of a DAPL expansion project which is estimated to occur in mid-2021. If transportation capacity on DAPL becomes restricted or unavailable, we have the ability to utilize other third party pipelines or rail facilities to transport our cash flows from operations, our remaining cash balance,Bakken crude oil production to market, although such alternatives may be more costly. The restriction of DAPL's takeaway capacity may have an impact on prices for Bakken-produced barrels and amounts available under our credit facility will be sufficientresult in wider differentials relative to satisfy such commitments and contingencies.WTI benchmark prices in the future, the amount of which is uncertain.
Dividend declarationpayments
In May 2019 ourTo preserve cash in response to the significant reduction in crude oil prices and economic uncertainty resulting from the COVID-19 pandemic, in April 2020 the Company’s quarterly dividend was suspended by the Board of Directors approved the initiation of a dividend payment program and on June 3, 2019 we announced a quarterly cash dividend of $0.05 per share on our outstanding common stock, payable on November 21, 2019 to shareholders of record on November 7, 2019. As of June 30, 2019 our dividend payment obligation is estimated to be approximately $18.7 million. Any future dividends beyond our initial November dividend are subject to approval by our Board of Directors. until further notice.


Share repurchase program
In May 2019 our Board of Directors approved the initiation of a share repurchase program to acquire up to $1 billion of our common stock beginning in June 2019 and expected to continue through 2020. Our repurchase program is one component of the Company’s shareholder return strategy that also includes the initiation of a quarterly dividend as discussed above. We intend to purchase shares under the program opportunistically using available funds while maintaining sufficient liquidity to fund our operating needs, capital program, and dividend payments. As of2019. Through June 30, 2019,2020, we had repurchased and retired 1,800,000a cumulative total of approximately 13.8 million shares under the program at an aggregate cost of $69.7 million. Our$317.1 million since the inception of the program. The timing and amount of the Company's share repurchases are subject to market conditions and management discretion. The share repurchase program does not require the Company to repurchase a specific number of shares and may be modified, suspended, or terminated by ourthe Board of Directors at any time. To preserve cash in the current environment, we do not expect to engage in significant share repurchase activity in the near term.
Senior note repurchases
As discussed in Note 8. Long-Term Debt in Notes to Unaudited Condensed Consolidated Financial Statements, in March and April 2020 we repurchased a portion of our 2023 Notes and 2024 Notes in open market transactions at a substantial discount to face value. From time to time, we may seek to execute additional repurchases of our senior notes for cash in open market transactions, privately negotiated transactions, or otherwise. Such repurchases will depend on prevailing market conditions, our liquidity and prospects for future access to capital, and other factors. The amounts involved in any such transactions, individually or in the aggregate, may be material.
Legislative and Regulatory Developments
On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") was signed into law, which is aimed at supporting the U.S. economy and providing emergency assistance to individuals, families, and businesses affected by the COVID-19 pandemic. In particular, key income tax-related provisions of the CARES Act include (1) elimination of the 80% of taxable income limitation by allowing entities to utilize 100% of net operating losses ("NOLs") to offset taxable income in 2018, 2019, or 2020, (2) allowing NOLs originating in 2018, 2019, or 2020 to be carried back to each of the preceding five years to generate a refund, (3) increasing the net interest expense deduction limit from 30% to 50% of adjusted taxable income for tax years beginning in 2019 and 2020, and (4) allowing taxpayers with alternative minimum tax credits to claim a refund in 2020 for the entire amount of the credit instead of recovering the credit through refunds over a period of years. The CARES Act is not expected to have a material impact on our business.
Off-balance sheet arrangements
Currently, we do not have any off-balance sheet arrangements with unconsolidated entities to enhance liquidity and capital resources.
Critical Accounting Policies
There have been no changes in our critical accounting policies from those disclosed in our 20182019 Form 10-K.


New Accounting Pronouncements

Non-GAAP Financial Measures
Net crude oil and natural gas sales and net sales prices
Revenues and transportation expenses associated with production from our operated properties are reported separately as discussed in Notes to Unaudited Condensed Consolidated Financial Statements–Note 4. Revenues. For non-operated properties, we receive a net payment from the operator for our share of sales proceeds which is net of costs incurred by the operator, if any. Such non-operated revenues are recognized at the net amount of proceeds received. As a result, the separate presentation of revenues and transportation expenses from our operated properties differs from the net presentation from non-operated properties. This impacts the comparability of certain operating metrics, such as per-unit sales prices, when such metrics are prepared in accordance with U.S. GAAP using gross presentation for some revenues and net presentation for others.
In order to provide metrics prepared in a manner consistent with how management assesses the Company's operating results and to achieve comparability between operated and non-operated revenues, we have presented crude oil and natural gas sales net of transportation expenses in Management’s Discussion and Analysis of Financial Condition and Results of Operations, which we refer to as "net crude oil and natural gas sales," a non-GAAP measure. Average sales prices calculated using net


crude oil and natural gas sales are referred to as "net sales prices," a non-GAAP measure, and are calculated by taking revenues less transportation expenses divided by sales volumes, whether for crude oil or natural gas, as applicable. Management believes presenting our revenues and sales prices net of transportation expenses is useful because it normalizes the presentation differences between operated and non-operated revenues and allows for a useful comparison of net realized prices to NYMEX benchmark prices on a Company-wide basis.
The following tables present a reconciliation of crude oil and natural gas sales (GAAP) to net crude oil and natural gas sales and related net sales prices (non-GAAP) for the three and six months ended June 30, 20192020 and 2018.2019.

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, 2019,2020, and excluding anythe effect of our derivative instruments in place, if any, our annual revenue would increase or decrease by approximately $707$540 million for each $10.00 per barrel change in crude oil prices at June 30, 20192020 and $302$293 million for each $1.00 per Mcf change in natural gas prices at June 30, 2019.2020.
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. We have hedged the majority of our forecasted natural gas production through December 2019. Our future crude oil production is currently unhedged and directly exposed to volatility in market prices, whether favorable or unfavorable.
Changes in natural gas prices during the six months ended June 30, 2019 had an overall favorable impact on the fair value of our derivative instruments. For the six months ended June 30, 2019, we recognized non-cash mark-to-market gains on natural gas derivatives of $30.6 million coupled with cash gains on natural gas derivatives of $21.7 million.
The fair value of our natural gascrude oil derivative instruments at June 30, 20192020 was a net assetliability of $46.2$10.1 million. An assumed increase in the forward prices used in the June 30, 20192020 valuation of our crude oil derivatives of $10.00 per barrel would increase our crude oil derivative liability to approximately $38 million at June 30, 2020. Conversely, an assumed decrease in forward prices of $10.00 per barrel would change our crude oil derivative valuation to a net asset of approximately $18 million at June 30, 2020.
The fair value of our natural gas derivative instruments at June 30, 2020 was a net asset of $9.4 million. An assumed increase in the forward prices used in the June 30, 2020 valuation of our natural gas derivatives of $1.00 per MMBtu would change our natural gas derivative valuation to a net liability of approximately $42$20 million at June 30, 2019.2020. Conversely, an assumed decrease in forward prices of $1.00 per MMBtu would increase our natural gas derivative asset to approximately $134$40 millionat June 30, 2019. 2020.
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 ($651176 million inreceivables at June 30, 2019);2020), and our joint interest and other receivables ($378151 million at June 30, 2019); and counterparty credit risk associated with our derivative instrument receivables ($46.2 million at June 30, 2019)2020).

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.immaterial; however, we could experience increased exposure to credit losses in the future if the adverse economic effects of the COVID-19 pandemic persist for an extended period.
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 $79$32 million at June 30, 2019,2020, 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 a co-owner's interest in the well, to redirectnet production proceeds against amounts owed in order to secure payment or, if necessary, foreclose on the co-owner's interest. Historically, our credit losses on joint interest receivables have been immaterial.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
however, we consider to be financially strong in order to minimize ourcould experience increased exposure to credit risk with any individual counterparty.

losses in the future if the adverse economic effects of the COVID-19 pandemic persist for an extended period.
Interest Rate Risk. Our exposure to changes in interest rates relates primarily to variable-rate borrowings if any, we may have outstanding from time to time under our credit facility. 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 March 2020, our corporate credit rating was downgraded by S&P in response to weakened oil and gas industry conditions and resulting revisions made to rating agency commodity price assumptions. The downgrade caused the interest rate on our credit facility borrowings to increase by 0.25% and also prompted a 0.05% increase in the rate of commitment fees paid on unused borrowing availability. 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 had no$647 million of variable rate borrowings outstanding borrowings on our credit facility at July 31, 2019.2020. The impact of a 0.25% increase in interest rates on this amount of debt would result in increased interest expense and reduced income before income taxes of approximately $1.6 million per year.
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.

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, 20192020 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, 2019,2020, 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.
Impact of COVID-19 on Internal Controls
In an effort to protect the health and safety of our employees from the COVID-19 pandemic, we have taken proactive measures to adopt social distancing policies, including limiting the number of employees attending meetings, reducing the number of people at our sites, and suspending employee business travel. These actions have not had a material adverse effect on our ability to maintain our operations, financial reporting systems, internal control over financial reporting, and disclosure controls and procedures.
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.
