CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report contains "forward-looking“forward-looking statements." All statements, other than statements of historical facts, included or incorporated by reference herein concerning, among other things, planned capital expenditures, increases in oil and gas production, the number of anticipated wells to be drilled or completed after the date hereof, future cash flows and borrowings, pursuit of potential acquisition opportunities, our financial position, business strategy and other plans and objectives for future operations, are forward-looking statements. These forward-looking statements are identified by their use of terms and phrases such as ''may," "expect," "estimate," "project," "plan," "believe," "intend," "achievable," "anticipate," ''will," "continue," ''potential," "should," "could,"“may,” “expect,” “estimate,” “project,” “plan,” “believe,” “intend,” “achievable,” “anticipate,” “will,” “continue,” “potential,” “should,” “could,” and similar terms and phrases. Although we believe that the expectations reflected in these forward-looking statements are reasonable, they do involve certain assumptions, risks and uncertainties. Review and consider the cautionary statements and disclosures, specifically those under Item 1A, Risk Factors, made in this report and our other filings with the Securities and Exchange Commission for further information on risk and uncertainties that could affect our business, financial condition, results of operations and cash flows. Our results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including, among others: 

our ability to execute on our business strategy following emergence from bankruptcy;
the COVID-19 pandemic, including its effects on commodity prices, downstream capacity, employee health and safety, business continuity and regulatory matters;
federal and state regulations and laws;
capital requirements and uncertainty of obtaining additional funding on terms acceptable to us;
risks and restrictions related to our debt agreements;
impact of political and regulatory developments in Colorado, particularly with respect to additional permit scrutiny;
our ability to use derivative instruments to manage commodity price risk;
realized oil, natural gas and NGL prices;prices as well as the volatility and widening of differentials;
a decline in oil, natural gas and NGL production, and the impact of general economic conditions on the demand for oil, natural gas and NGL and the availability of capital;
asset impairments from commodity price declines;
the willingness of the Organization of Petroleum Exporting Countries (“OPEC”) to set and maintain production levels;
unsuccessful drilling and completion activities and the possibility of resulting write-downs;
geographical concentration of our operations;
constraints in the DJ Basin of Colorado with respect to gathering, transportation and processing facilities and marketing;

Reserve engineering is a process of estimating underground accumulations of oil, natural gas, and NGL that cannot be measured in an exact way. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data and price and cost assumptions made by reserve engineers. In addition, the results of drilling, testing and production activities may justify revisions of estimates that were made previously. If significant, such revisions would change the schedule of any further production and development drilling. Accordingly, reserve estimates may differ significantly from the quantities of oil, natural gas and NGL that are ultimately recovered.
 
All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements in this section and elsewhere in this Annual Report. Except as required by law, we do not assume a duty to update these forward-looking statements, whether as a result of new information, subsequent events or circumstances, changes in expectations or otherwise.

Company Overview
 
We are an independent oil and gas company focused on the acquisition, development and production of oil, natural gas and NGL reserves in the Rocky Mountain region, primarily in the Wattenberg Field of the Denver-Julesburg Basin (the “DJ Basin”) of Colorado. The Wattenberg Field has been producing since the 1970s and is a premier North American oil and natural gas basin characterized by high recoveries relative to drilling and completion costs, high initial production rates, long reserve life and multiple stacked producing horizons. We have assembled, as of December 31, 2017,2020, approximately 171,400140,000 net acres of large, contiguous acreage blocks in some of the most productive areas of the DJ Basin, indicated by the results of our horizontal drilling program and the results of offset operators, which we refer to as the “Core DJ Basin”.  The 171,400 net acres includes our new acquisition area (the "Hawkeye Area") in Arapahoe and Adams Counties, which makes up approximately 68,700 of the 171,400 net acres.Basin.” We believe our acreage in the Core DJ Basin has been significantly delineated by our own drilling success and by the success of offset operators, providing confidence that our inventory is operationally relatively low-risk, repeatable and will continue to generate economic returns. We are primarily focused on growing our proved reserves and production primarily through the development of our large inventory of identified liquids-rich horizontal drilling locations in the DJ Basin.

We were founded in November 2012 with the objective of becoming a Wattenberg focused company with acreage that has (i) low geologic development risk as a result of being within the vicinity of other successful wells drilled by other oil and gas companies, (ii) limited vertical well drainage relative to offset operators in a field with significant historical vertical activity, and (iii) higher oil content than was traditionally targeted when many operators first established their position in the field seeking natural gas production. We believe these characteristics enhance our horizontal production capabilities, recoveries and economic results. Our drilling economics are further enhanced by our ability to drill longer laterals due to our large contiguous acreage position, which our management team built through organic leasing and a series of strategic acquisitions. We operated 94%99% of our horizontal production for the year ended December 31, 20172020 and maintain control of a large majority of our drilling inventory. In addition, we proactively seek to secure the necessary midstream and operational infrastructure to keep pace with our production growth.
 
For the year ended December 31, 2017,2020, we have drilled 32337 gross one-mile equivalentwells with an average lateral length of 2.3 miles and completed 45 gross wells with an average lateral length of 2.4 miles, all of which were horizontal wells in the DJ Basin. During 2020, we laid down both or our rigs. During 2021, we began using a rig again and have completed 332 gross one-mile equivalent horizontal wells. We are currently running a full time three-rig program and our 2018one-rig program. Our 2021 capital budget anticipates a twoone-rig drilling program we expect to three operated drilling rig program.operate most of the year. Our average net daily production during the fourth quarter and year ended December 31, 20172020 was approximately 66,13482,944 BOE/d and 51,76488,907 BOE/d, respectively.

Our Properties
 
Core DJ Basin
 
Our current operations are located in the DJ Basin, primarily in the Wattenberg Field where we target the oil and liquids-weighted Niobrara and Codell formations. As of December 31, 2017,2020, our position in the Core DJ Basin consisted of approximately 171,400140,000 net acres.
 
Our estimated proved reserves at December 31, 20172020 were 292.7145.9 MMBoe. As of December 31, 2017,2020, we had a total of 1,3001,322 gross wells capable of producing, wells, of which 652841 were horizontal wells. The vertical wells we operate primarily serve to hold leases until we can drill more efficient horizontal wells on acreage we lease. Therefore, production from vertical wells

does not represent a material amount of our current production and is anticipated to decline as a percentage of total production in the future as we drill more horizontal wells. Our average net daily production during the year ended December 31, 2017 was approximately 51,429 BOE/d. Our working interest for all wells capable of producing wells averages approximately 71%79% and our net revenue interest is approximately 58%65%.
 
We continue to expand our proved reserves in this area by drilling non-proved horizontal locations. As of December 31, 2017,2020, we had an identified drilling inventory of approximately 70165 gross (375(48 net) proved undeveloped horizontal drilling locations with varying lateral lengths on our acreage with average gross drill and complete well costs of $4.6 million ($2.7 million normalized to 4,200 foot lateral length).$4.2 million. During 2017,2020, we drilled 18637 gross operated horizontal wells and completed 19845 gross operated horizontal wells.


Other Properties
 
We hold approximately 183,30096,700 net acres outside of the Core DJ Basin, which we refer to as our “Other Rockies Area,” that we believe is prospective for many of the same formations as our properties in the Core DJ Basin. As of December 31, 2017,2020, there were de minimis proved reserves associated with this acreage. Average daily production associated with these properties for the year ended December 31, 2017 was approximately 335 BOE/d.

Our 20182021 capital budget for the drilling and completion of operated and non-operated wells is approximately $890$140 million to $990$180 million, substantially all of which we intend to allocate to the Core DJ Basin. We intend to allocate approximately $770 million to $840 million of our 2018 capital budget to operated and non-operated drilling and completion of new wells. We expect to drill 170 to 17534 gross operated wells, complete 49 gross operated wells and complete 185 to 190turn-in-line 44 gross operated wells. Approximately $120 million to $150 million is expected to be allocated to acreage leasing, midstream, and other capital expenditures.wells with estimated lateral lengths of 2.2 miles. Our 2021 capital budget anticipates a two to three operated rigone-rig drilling program and excludes any amounts that may be paid for potential acquisitions.we expect to operate most of the year.
 
The amount and timing of these capital expenditures is within our control and subject to our management’s discretion. We retain the flexibility to defer or accelerate a portion of these planned capital expenditures depending on a variety of factors, including but

not limited to the success of our drilling activities, prevailing and anticipated prices for oil, natural gas and NGL,NGLs, the availability of necessary equipment, infrastructure and capital, the receipt and timing of required regulatory permits and approvals, seasonal conditions, drilling and acquisition costs and the level of participation by other interest owners. Any postponement or elimination of our development drilling program could result in a reduction of proved reserve volumes and related standardized measure. These risks could materially affect our business, financial condition and results of operations.

Recent Developments

Recent AcquisitionsEmergence from Chapter 11 Bankruptcy

On June 14, 2020, we commenced voluntary cases under chapter 11 of title 11 (“Chapter 11”) of the United States Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”). The Debtors’ Chapter 11 cases are being jointly administered under the caption In re Extraction Oil & Gas, Inc., et al. (the “Chapter 11 Cases”). On December 23, 2020, we filed the Sixth Amended Joint Plan of Reorganization of Extraction Oil & Gas, Inc. (the “Plan”) pursuant to Chapter 11 of the Bankruptcy Code. The Bankruptcy Court also entered an order confirming the Plan. The Plan and Divestituresthe Confirmation Order were filed as Exhibits 2.1 and 99.1 to our Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission on December 30, 2020. On January 20, 2021 (the “Emergence Date”) the Plan became effective in accordance with its terms and we emerged from the Chapter 11 Cases. Please see Note 1 — Business and Organization in Part II, Item 8. Financial Information of this Annual Report for information on the Plan and emergence from Chapter 11 bankruptcy and discussion of our RBL Credit Facility and capital activity associated with emergence from the Chapter 11 Cases.


Asset DivestituresElevation Gathering Agreements


ToIn April 2020, pursuant to an amendment to the Elevation Gathering Agreements made in April 2019 (as discussed in Note 16 — Commitment and Contingencies in Part II, Item 8. Financial Information of this Annual Report) Elevation asserted that Extraction had missed the deadline for completion of additional gathering facilities and, therefore, that Extraction must make a payment to Elevation in the amount of 135% of all costs incurred by Elevation as of such date for the development and construction of such additional gathering facilities. On April 2, 2020, Elevation demanded payment of $46.8 million due to an alleged breach in contract stemming from a purported failure to complete the pipeline extensions connecting certain wells to the Badger central gathering facility prior to April 1, 2020.

On December 15, 2020, the Company and Elevation reached an agreement regarding amendments to the gathering agreements and the settlement of all outstanding claims. As part of the settlement, we will pay Elevation $38.4 million in cash over 24 months, and Elevation submitted an unsecured claim of $80.0 million with the Bankruptcy Court. The agreement released certain areas from future dedication, provided a reduction in certain gathering fees, a reduction in the number of wells

subject to the drilling commitment, and an extended term in order to satisfy the drilling commitment. The Company also relinquished the nominal common interest ownership it had in Elevation. The Company had previously accrued $46.8 million and $4.2 million of accrued interest related to the aforementioned alleged breach in contract. During the third quarter of 2020, the Company accrued an additional $68.7 million within liabilities subject to compromise on the consolidated balance sheets and in reorganization items, net on the consolidated statements of operations.

Rejection and Renegotiation of Midstream Contracts

During the third and fourth quarters of 2020, the majority of our material midstream contracts were renegotiated or rejected by the Bankruptcy Court as part of the Chapter 11 Cases. As a result of these renegotiated or rejected contracts, the Company eliminated the majority of its minimum volume commitments as described in Note 16 — Commitment and Contingencies— Delivery Commitments in Part II, Item 8. Financial Information of this Annual Report and accrued $550.5 million within liabilities subject to compromise on the consolidated balance sheets as of December 31, 2020 and in reorganization items, net on the consolidated statements of operations for the year ended December 31, 2020.

NASDAQ Delisting and Relisting

Our common stock was traded on the NASDAQ Global Select Market (the “NASDAQ”) under the symbol “XOG” prior to June 25, 2020. On June 16, 2020, we received a letter from the NASDAQ notifying us that, as a result of the Chapter 11 Cases and in accordance with NASDAQ rules, our securities would be delisted at the opening of business on June 25, 2020. On June 25, 2020, our common stock began to be quoted on the Pink Open Market under the symbol “XOGAQ”. In connection with our emergence from bankruptcy, our common stock was relisted on the NASDAQ Global Select Market on January 21, 2021 trading under the symbol “XOG.”

COVID-19 Outbreak and Global Industry Downturn

The recent worldwide outbreak in several countries, including the United States, of a highly transmissible and pathogenic coronavirus (“COVID-19”) and the uncertainty regarding the impact of COVID-19 and various governmental actions taken to mitigate the impact of COVID-19 have received multipleresulted in an unprecedented decline in demand for oil and natural gas. At the same time, the decision by Saudi Arabia in March 2020 to drastically reduce export prices and increase oil production followed by curtailment agreements among OPEC and other countries such as Russia further increased uncertainty and volatility around global oil supply-demand dynamics. Decreased demand from much of the United States being on lockdown to divest various properties for approximately $70.0 million. These salesprevent the spread of COVID-19 caused domestic storage capacity to begin to fill up during March and April of 2020 causing further price declines and ultimately causing oil prices to plummet. More recently, however, reduction in oil and gas activity as a result of the COVID-19 pandemic has resulted in a decrease of production as fewer oil wells are not expecteddrilled, which has led to a contraction in domestic oil and gas supply. Lower levels of supply have pushed current and forecasted oil and gas prices higher, which we expect to have a materialpositive impact on our results of operations and cash flows. We expect that the reduction in drilling activity and rig counts may contribute to our previously announced 2018 guidancea shortage in the supply of oil and are projected to close duringnatural gas in the second quarter of 2018.

November 2017 Acquisition

On November 15, 2017, we acquired an unaffiliatedfuture, which could result in higher oil and gas company's interestprices. As a result, although oil and gas prices were on average lower in 2020 than 2019, oil and gas prices trended higher after the effects of the COVID-19 pandemic began to take hold and slow oil production towards the middle of 2020.

The COVID-19 outbreak and its development into a pandemic in March 2020 have required that we take precautionary measures intended to help minimize the risk to our business, employees, customers, suppliers and the communities in which we operate. Our operational employees are currently still able to work on site. However, we have taken various precautionary measures with respect to such operational employees such as requiring them to verify they have not experienced any symptoms consistent with COVID-19, or been in close contact with someone showing such symptoms, before reporting to the work site, quarantining any operational employees who have shown signs of COVID-19 (regardless of whether such employee has been confirmed to be infected) and imposing social distancing requirements on work sites, all in accordance with the guidelines released by the Center for Disease Control. In addition, most of our non-operational employees are now working remotely. We have not yet experienced any material operational disruptions (including disruptions from our suppliers and service providers) as a result of the COVID-19 outbreak.

Due to the decline in crude oil prices in 2020 and ongoing uncertainty regarding the oil supply-demand macro environment, we reduced our operations in order to preserve capital. Specifically, as part of the Chapter 11 Cases, we rejected our drilling rig contracts and certain equipment and compression agreements as discussed in Note 16—Commitments and Contingencies in Part II, Item 8.

Involuntary Termination Charges

During the first and second quarters of 2020, we recorded involuntary termination charges of $7.6 million primarily related to one-time involuntary termination benefits, office closure and relocation benefits communicated to our workforce in February 2020. This plan was initiated to align the size and composition of our workforce with our expected future operating and capital plans.

Divestitures

In February 2020, we completed the sale of certain non-operated producing properties for aggregate sales proceeds of approximately 36,600 net acres of leasehold and primarily non-producing properties located in Arapahoe County, Colorado, (the "November 2017 Acquisition"). Upon closing the seller received $214.3$12.2 million, in cash, subject to customary purchase price adjustments. No gain or loss was recognized. We also recorded a liabilitycontinue to explore divestitures as part of $12.2 million forour ongoing initiative to divest non-strategic assets.

Senate Bill 19-181 “Protect Public Welfare Oil and Gas Operations”

In April 2019, Senate Bill 19-181 (“SB181”) became law, increasing the final settlement payment dueregulatory authority of local governments in April 2018 in conjunction withColorado over the November 2017 Acquisition for total considerationsurface impacts of $226.5 million. The acquisition provides new development opportunities in the DJ Basin.
July 2017 Acquisition
On July 7, 2017, we acquired an unaffiliated oil and gas company’s interestdevelopment in approximately 12,500 net acres of leaseholda necessary and primarily non-producing properties locatedreasonable manner, and in Adams County, Colorado, along with various other related rights, permits, contracts, equipment, rights of way, gathering systems and other assets. Upon closing the seller received total consideration of $84.0 million in cash.
June 2017 Acquisition
On June 8, 2017, we acquired an unaffiliatedOctober 2020, Colorado’s Air Quality Control Commission (“AQCC”) adopted new rules targeting air emissions from upstream oil and gas company's interestsoperation. Among other things, SB181 (i) repeals a prior law restricting local government land use authority over oil and gas mineral extraction areas to areas designated by the COGCC, (ii) directs the AQCC to review its leak detection and repair rules and to adopt rules to minimize emissions of certain air pollutants, (iii) clarifies that local governments have authority to regulate the siting of oil and gas locations in producing properties located in Weld County, Colorado. The acquisition increased our interest in existing operated wells. We paid approximately $13.4 million in cash consideration in connection witha necessary and reasonable manner, including the closingability to inspect oil and gas facilities, impose fines for leaks, spills, and emissions, and impose fees on operators or owners to cover regulation and enforcement costs, (iv) allows local governments or oil and gas operators to request a technical review board to evaluate the effect of the acquisition. The acquired interest contributed $3.7 millionlocal government’s preliminary or final determination on the operator’s application, (v) repeals an exemption for oil and gas production from counties’ authority to regulate noise, (vi) alters forced pooling requirements by increasing the threshold to compel non-consenting individuals into statutory pooling agreements and (vii) prioritizes the protection of revenuepublic health, safety, and $3.0 millionwelfare, the environment, and wildlife resources in the regulation of earnings foroil and gas development. Although industry trade associations opposed SB181, Extraction has demonstrated an ability to continue to successfully operate our business. However, the year ended December 31, 2017.
Amendments to Revolving Credit Facility and Capital Raises

2026 Senior Notes
On January 25, 2018, we issued at par $750.0 million principal amountenactment of 5.625% Senior Notes due February 1, 2026 (the "2026 Senior Notes"SB181 and the offering,development and implementation of related rules and regulations, which is under way, could lead to delays and additional costs to our business. Also, certain interest groups in Colorado opposed to oil and natural gas development generally have in previous years advanced various alternatives for ballot initiatives which would result in significantly limiting or preventing oil and natural gas development in the "2026 Senior Notes Offering"). The 2026 Senior Notes bear an annual interest ratestate.

Resulting from Colorado’s adoption of 5.625%. The interest onSB181 during 2019, the 2026 Senior Notes is payable on February 1 and August 1 of each year commencing on August 1, 2018. We received net proceeds of approximately $737.9 million after deducting discounts and fees. We used approximately $534.2 million of the net proceeds from the 2026 Senior Notes Offering to tender for our 7.875% Senior Notes due 2021 ("2021 Senior Notes"), $52.7 million to redeem any 2021 Senior Notes not tendered and the remainderCOGCC recently promulgated rules associated with that legislation that will, be used for general corporate purposes. As of January 18, 2018, our borrowing base under our revolving credit facility was $750.0 million. Although the borrowing base under our revolving credit facility was automatically reduced to $700.0 million in connection with the closing of the 2026 Senior Notes Offering, there has been no change to the current maximum lending commitments of $650.0 million.

Tender Offer to Purchase 2021 Senior Notes

On January 25, 2018, we announced the results of our cash tender offer to purchase any and all of the outstanding aggregate principal amount of the 2021 Senior Notes. An aggregate principal amount of $500.6 million (91%) was tendered and paid, in addition to a make-whole premium of $32.6 million and accrued and unpaid interest of $1.0 million, on January

25, 2018. On February 17, 2018, we redeemed the approximately $49.4 million aggregate principal amount of the 2021 Senior Notes that remained outstanding after the Tender Offer and made a cash payment of approximately $52.7 million to the remaining holders of the 2021 Senior Notes, which includes a make-whole premium of $3.0 million and accrued and unpaid interest of approximately $0.3 million.
January 2018 Credit Facility Amendment

On January 5, 2018, we amended the revolving credit facility to (i) increase the borrowing base from $525.0 million to $750.0 million, subject to the current maximum lending commitments of $650.0 million, (ii) increase the maximum amount for the letter of credit issued in favor of a purchaser of our crude oil from $25.0 million to $35.0 million, and (iii) amend certain provisions of the credit agreement, including the commitments and allocations of each lender. In connection with the 2026 Senior Notes Offering, the borrowing base was automatically reduced to $700.0 million; however, the current maximum lending commitments remained $650.0 million. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations–Liquidity and Capital Resources–Revolving Credit Facility.”
October 2017 Credit Facility Amendment

On October 11, 2017, we amended the revolving credit facility to, among other things, (i) provideimpose mandatory 2,000 foot setbacks for the joinder of new lenders, (ii) increase the borrowing base under the credit facility from $375.0 million to $525.0 million,all schools and (iii) amend certain provisions of the credit agreement, including the commitments and allocations of each lender. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations–Liquidity and Capital Resources–Revolving Credit Facility.”

August 2017 Credit Facility Amendment and Restatement
On August 16, 2017, we entered into an amendment and restatement of our existing credit facility, which provides commitments of $1.5 billion with a syndicate of banks, which was subject to a borrowing base of $375.0 million. The credit facility matures on the earlier of (a) August 16, 2022, (b) January 15, 2021 if (and only if) our 2021 Senior Notes (as defined below) have not been refinanced or repaid in full on or prior to January 15, 2021, (c) April 15, 2021, if (and only if) (i) the convertible preferred equity interests issued by us has not been converted into common equity or redeemed prior to April 15, 2021, and (ii) prior to April 15, 2021, the maturity date of the Series A Preferred Stock has not been extended to a date that is no earlier than six months after August 16, 2022 or (d) the earlier termination in whole of the commitments. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations–Liquidity and Capital Resources–Revolving Credit Facility.”
2024 Senior Notes
On August 1, 2017, we issued at par $400.0 million principal amount of 7.375% Senior Notes due May 15, 2024 (the "2024 Senior Notes" and the offering, the "2024 Senior Notes Offering"). The 2024 Senior Notes bear an annual interest rate of 7.375%. The interest on the 2024 Senior Notes is payable on May 15 and November 15 of each year commencing on November 15, 2017. We received net proceeds of approximately $392.6 million after deducting discounts and fees. We used the net proceeds from the 2024 Senior Notes Offering to partially fund our 2017 capital expenditures and for general corporate purposes.

Drilling Locations
As of December 31, 2017, we have identified a total of 5,800 gross identified drilling locations as adjusted to one-mile equivalents. Our target horizontal location count implies lateral lengths of 4,200 feet per well. Approximately 12% of our gross identified drilling locations are attributable to proved undeveloped reserves. Our identified drilling locations have been identified based on our review of structurechildcare centers, as well as new siting criteria for any oil and gas locations that are within 2,000 feet of building units. The rules additionally require local government permitting approval that could add additional timing and complexity and potentially lengthen the pace of the oil and gas permitting process. These new rules went into effect on January 15, 2021.

Though these new siting zones add a number of new criteria for permitting, at this time, the promulgation of these rules has not resulted in any significant changes to our development plans. Extraction has all necessary state and local approvals for 188 permits to drill wells over the next several years. However, due to the necessary learning process associated with the promulgation of new COGCC rules, we could experience delays and/or curtailment in the permitting or pursuit of exploration, development or production data from offsetting wells. Weactivities. Such compliance requirements may lead to delays and additional costs to our operations and reduce the area available for future development of our operations. The discretion with which these new rules are interpreted and enforced by the new COGCC could additionally have internally generated this production data baseda material adverse effect on our evaluationbusiness, financial condition, and results of an extensive geological and engineering database. Information incorporated into this process includes both our own proprietary information as well as publicly available industry data. Specifically, open hole logging data, production statistics from operated and non-operated wells, and petrophysical data from cores taken from wellbores have provided the technical basis from which we identified the potential locations. These data have allowed us to determine areas for each reservoir that may produce commercial quantitiesoperations.

Evaluation and Review of Proved Reserves


Our historical proved reserves estimates as of December 31, 2017, 20162020, 2019 and 20152018 were prepared based on reports by Ryder Scott Company, L.P. ("(“Ryder Scott"Scott”), our independent petroleum engineers. Within Ryder Scott, the technical person primarily responsible for preparing the estimates set forth in the Ryder Scott summary reserve reports incorporated herein is Richard Marshall.for the year ended December 31, 2020 was Stephen Gardner. Mr. MarshallGardner has been practicing consulting petroleum engineering at Ryder Scott since 1981.2006. Mr. MarshallGardner is a registered Professional Engineer in the State of Colorado and Texas and has over 3015 years of practical experience in the estimation and evaluation of reserves. Mr. MarshallGardner graduated from the Brigham Young University of Missouri in 1974 with a Bachelor of Science Degree in Geology and from the University of Missouri at Rolla in 1976 with a Master of Science Degree in GeologicalMechanical Engineering. As technical principal, Mr. MarshallGardner meets or exceeds the education, training, and experience requirements set forth in the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers and is proficient in applying industry standard practices to engineering evaluations as well as applying SEC and other industry reserves definitions and guidelines. Ryder Scott does not own an interest in any of our properties, nor is it employed by us on a contingent basis. Ryder Scott'sScott’s report is attached as Exhibit 99.1 to this Annual Report on Form 10-K.


We maintain an internal staff of petroleum engineers and geoscience professionals who work closely with our independent reserve engineers to ensure the integrity, accuracy and timeliness of the data used to calculate our proved reserves relating to our assets in the DJ Basin. Our internal technical team members meet with our independent reserve engineers periodically during the period covered by the proved reserve report to discuss the assumptions and methods used in the proved reserve estimation process. We provide historical information to the independent reserve engineers for our properties, such as ownership interest, oil and natural gas production, well test data, commodity prices and operating and development costs. These reserve estimates are reviewed and approved by our LeadCorporate Reserves Manager. The reserves are also reviewed by our management and Performance Engineer with final approval by Senior Vice Presidenta committee of Operations.the Board of Directors (the “Board”).


Our Senior Vice President of Operations oversees our corporate strategic planning, reservoir reserves, operations, environmental and regulatory affairs. HeCorporate Reserves Manager is the technical person primarily responsible for overseeing the preparation of our reserves estimates and third-party auditreport of our reserves estimates. HeShe holds a Bachelor of Science in environmental engineering andmathematics with a Master of Sciencetechnical minor in petroleum engineering withand has over 2332 years of industry experience, primarily in reservoir engineering, reserve estimation, and significant DJ Basin technicaleconomic evaluation and operational expertise. The Senior Vice President of Operations reports directly to our President.modelling across multiple conventional and unconventional basins.

Our policies and processes regarding internal controls over the recording of reserves estimates require reserves to be in compliance with the SEC definitions and guidance and prepared in accordance with Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers. Our internal controls over reserves estimates also include the review and verification of historical production data, which are based on actual production data as reported by us; preparation of reserve estimates and verification of property ownership by our land department. Additionally, 100% of our total net proved reserves are evaluated by Ryder Scott, on an annual basis.
 
Estimation of Proved Reserves
 
Under SEC rules, proved reserves are those quantities of oil, natural gas and NGL, 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 that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. If deterministic methods are used, the SEC has defined reasonable certainty for proved reserves as a “high degree of confidence that the quantities will be recovered.” All of our proved reserves as of December 31, 2015, 20162020, 2019 and 20172018 were estimated using a deterministic method. The estimation of reserves involves two distinct determinations. The first determination results in the estimation of the quantities of recoverable oil, natural gas and NGL and the second determination results in the estimation of the uncertainty associated with those estimated quantities in accordance with the definitions established under SEC rules. The process of estimating the quantities of recoverable oil, natural gas and NGL reserves relies on the use of certain generally accepted analytical procedures. These analytical procedures fall into four broad categories or methods: (1) production performance-based methods; (2) material balance-based methods; (3) volumetric-based methods; and (4) analogy. These methods may be used singularly or in combination by the reserve evaluator in the process of estimating the quantities of reserves. Reserves for proved developed producing wells were estimated using production performance methods for the vast majority of properties. Certain new producing properties with very little production history were forecast using a combination of production performance and

analogy to similar production, both of which are considered to provide a relatively high degree of accuracy. Non-producing reservemethods. Reserve estimates for developed and undeveloped properties were forecast using either volumetric or analogy methods, or a combination of both.methods. These methods provide a relatively high degree of accuracy for predicting proved developed non-producing and proved undeveloped reserves for our properties, due to the mature nature of the properties targeted for development and an abundance of subsurface control data.

To estimate economically recoverable proved reserves and related future net cash flows, Ryder Scott considered many factors and assumptions, including the use of reservoir parameters derived from geological and engineering data which cannot be measured directly, economic criteria based on current costs and the SEC pricing requirements and forecasts of future production rates.
  
Under SEC rules, reasonable certainty can be established using techniques that have been proven effective by actual production from projects in the same reservoir or an analogous reservoir or by other evidence using reliable technology that establishes reasonable certainty. Reliable technology is a grouping of one or more technologies (including computational methods) that has been field tested and has been demonstrated to provide reasonably certain results with consistency and repeatability in the formation being evaluated or in an analogous formation. To establish reasonable certainty with respect to our estimated proved reserves, the technologies and economic data used in the estimation of our proved reserves have been demonstrated to yield results with consistency and repeatability, and include production and well test data, downhole completion information, geologic data, electrical logs, radioactivity logs, core analyses, historical well cost and operating expense data.

Reserve engineering is and must be recognized as a subjective process of estimating volumes of economically recoverable oil and natural gas that cannot be measured in an exact manner. The accuracy of any reserve estimate is a function of the quality of available data and of engineering and geological interpretation. As a result, the estimates of different engineers often vary. In addition, the results of drilling, testing and production may justify revisions of such estimates. Accordingly, reserve estimates often differ from the quantities of oil and natural gas that are ultimately recovered. Estimates of economically recoverable oil and natural gas and of future net revenues are based on a number of variables and assumptions, all of which may vary from actual results, including geologic interpretation, prices and future production rates and costs. Please read “Risk Factors” appearing elsewhere in this Annual Report.
Additional information regarding our proved reserves can be found in the notes to our financial statements included elsewhere in this Annual Report.
 
Proved Undeveloped Reserves (“PUDs”)


Annually, management develops a five-year capital expenditure plan based on our best available data at the time the plan is developed. Our capital expenditure plan incorporates a development plan for converting PUD reserves to proved developed.Proved developed reserves. The development plan includes only PUD reserves that we are reasonably certain will be drilled within five years of booking based upon management’s evaluation of a number of qualitative and quantitative factors, including estimated risk-based returns; estimated well density; commodity prices and cost forecasts; recent drilling recompletion or re-stimulation results and well performance; anticipated availability of services, equipment, supplies and personnel; and seasonal weather. This process is intended to ensure that PUD reserves are only booked for locations where a final investment decision has been made. Our five year development plan generally does not contemplate a uniform (i.e. 20% per year) conversionmade based on current corporate strategy. In an effort to maximize value to the shareholders, the company has elected to increase the spacing between wells drilled in several areas of the Core Wattenberg, thus drilling fewer wells. The company is currently only booking two years of drilling inventory as PUD. The remainder of our PUD reserves.drilling inventory in our capital expenditure plan is currently classified in non-proved reserve categories.

Management reviewswill continue to review and revisesrevise the development plan throughout the year and may modify the development plan after evaluating a number of factors, including operating and drilling results; current and expected future commodity prices; estimated risk-based returns; estimated well density; advances in technology; cost and availability of services, equipment, supplies and personnel; acquisition and divestiture activity; and our current and projected financial condition and liquidity. If there are changes that result in certain PUD reserves no longer being scheduled for development within five years from the date of initial booking, we reclasswill reclassify those PUD reserves to non-proved reserve categories. In addition, PUD locations and reserves may be removed from the development plan ahead of their five-year life expiration as a result of changes in our development plan related to factors enumerated above.

As of December 31, 2017,2020, our proved undeveloped reserves were composed of 74,19712,025 MBbls of oil, 403,93380,766 MMcf of natural gas and 49,1748,098 MBbls of NGL, for a total of 190,69333,583 MBoe. PUDs will be converted from undeveloped to developed as the applicablenecessary and required capital has been invested and the wells begin production.are capable of producing.

The following table summarizes our changes in PUDs during the years ended December 31, 2020, 2019 and 2018:

Extensions and discoveries of 8,714 MBoe, 26,776 MBoe and 64,955 MBoe during the years ended December 31, 2020, 2019 and 2018, respectively, resulted primarily from new proved undeveloped locations added as a result of the drilling and completion of new wells. Downward revisions of previous estimates of 62,556 MBoe during the year ended December 31, 2020 under changes in well performance, timing and other includes 23,926 MBoe of downward revisions of PUD expirations due to the five year rule caused by a continued reduction in planned capital spending to generate positive cash flow. The majority of these reserves (69%) were reclassified to a non-proved reserve category (Probable). Additionally, 26,515 MBoe of the 62,556 MBoe downward revisions were due to altering the development plan to increase the spacing between wellbores, thus drilling fewer wells. Downward revisions of previous estimates of 72,019 MBoe during the year ended December 31, 2019 under changes in well performance, timing and other consists primarily of revisions of PUD expirations due to the SEC five year drilling rule caused by the change in business strategy to focus on cash flow rather than maximizing production and reserves growth. Of the 72,019 MBoe downward revision of previous estimates, 69,731 MBoe was due the reclassification of reserves to non-proved categories due to the aforementioned PUD expirations. An additional 5,483 MBoe of the downward revision of previous estimates was due to PUDs becoming uneconomic due to negative changes in SEC pricing at December 31, 2019. Downward revisions of previous estimates of 20,080 MBoe during the year ended December 31, 2018 resulted primarily from the revisions resulting from price changes and revisions resulting from production and performance.
 
Estimated future development costs relating to the development of PUDs at December 31, 20172020 were projected to be approximately $390.7$61.7 million for the year ending December 31, 2018, $415.52021, $116.3 million in 2019, $291.2 million in 2020, $270 million in 20212022 and $273.8 million in 2022.none thereafter. Costs incurred relating to the development of PUDs that were $442.5developed were $69.8 million, $161.4$326.9 million and $94.6$392.3 million during the years ended December 31, 2017, 20162020, 2019 and 2015,2018, respectively. As we continue to develop our properties and have more well production and completion data, we believe we will continue to realize cost savings and experience lower relative drilling and completion costs as we convert PUDs into proved developed reserves in upcoming years. All of our PUD drilling locations are scheduled to be drilled within five years of their initial booking. We converted 43,79823,532 MBoe, 15,92349,713 MBoe and 7,22339,498 MBoe to proved developed producing reserves in the years ended December 31, 2017, 20162020, 2019 and 2015,2018, respectively. During the year ended December 31, 2017,2020, we converted 10933 PUD locations to proved developed producing reserves, which represent 23%represented 21% of our PUD reserve volumes and 16%14% of our PUD locations as of December 31, 2016.2019.

Productive Wells
 
As of December 31, 2017,2020, we owned an average 71%79% working interest in 1,3001,322 gross (916(1,041 net) productive wells. As of December 31, 2016,2019, we owned an average 73%72% working interest in 1,0141,509 gross (738(1,086 net) productive wells. As of December 31, 2015,2018, we owned an average 64%74% working interest in 5951,538 gross (384(1,139 net) productive wells. Productive wells consist of producing wells and wells capable of production, including oil wells awaiting connection to production facilities. Gross wells are the total number of producing wells in which we have an interest, and net wells are the sum of our fractional working interests owned in gross wells.


The following table sets forth information relating to the productive wells in which we owned a working interest as of December 31, 2020:

Developed and Undeveloped Acreage
 
The following tables set forth information as of December 31, 20172020 relating to our leasehold acreage. Developed acreage is acres spaced or assigned to productive wells and does not include undrilled acreage held by production under the terms of the lease. Undeveloped acreage is acres on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of oil and/or natural gas, regardless of whether such acreage contains proved reserves.

Drilling Results
 
The following table sets forth information with respect to the number of wells completed by us during the periods indicated. The information should not be considered indicative of future performance, nor should it be assumed that there is necessarily any correlation between the number of productive wells drilled, quantities of reserves found or economic value. Productive wells are those that produce commercial quantities of hydrocarbons, whether or not they produce a reasonable rate of return.

Operations
 
General
 
We operated 94%99% of our horizontal production for the year ended December 31, 2017.2020. As operator, we design and manage the development of a well and supervise operation and maintenance activities on a day-to-day basis. Independent contractors engaged by us provide all the equipment and personnel associated with these activities. We employ petroleum engineers, geologists and land professionals who work to improve production rates, increase reserves and lower the cost of operating our oil and natural gas properties.
 
Marketing and Customers
 
We sell the majority of the production from properties we operate for both our account and the account of the other working interest owners in these properties. We sell our production to purchasers at market prices. Our largest purchaser is an oil marketer who has the ability to sell production into multiple markets.
 
During the year ended December 31, 2017,2020, approximately 95%56% of our production was sold to three customers. However, we do not believe that the loss of aany single purchaser including these three, would materially affect our business because there are numerous other potential purchasers in the area in which we sell our production. For the yearsyear ended December 31, 2017, 20162020, Mercuria Energy Trading, Inc., Rocky Mountain Midstream, and 2015 purchases by the following companies exceeded 10%Concord Energy represented 28%, 16%, and 12%, respectively, of our total oil, gas and NGL revenues. For the year ended December 31, 2019, Mercuria Energy Trading, Inc. represented 77% of our total oil, gas and NGL revenues. For the year ended December 31, 2018, Mercuria Energy Trading, Inc. represented 76% and DCP Midstream represented 11% of our total oil, gas and NGL revenues. During 2021, we do not currently sell to Mercuria Energy Trading, Inc. or Concord Energy. Rather, we have increased our sales to Rocky Mountain Midstream and NGL Crude Logistics LLC who has replaced Mercuria Energy Trading, Inc. as our midstream oil marketer.

Transportation and Gathering
 
During the initial development of our fields, we consider all gathering and delivery infrastructure in the areas of our production. Our oil is collected from the wellhead to our tank batteries and then transported by the purchaser by truck or pipeline to a tank farm, another pipeline or a refinery. Our natural gas is transported from the wellhead to the purchaser’s meter and pipeline interconnection point.
We are subject to long-term delivery During the third and fourth quarters of 2020, the majority of our material midstream contracts were renegotiated or rejected by the Bankruptcy Court as part of the Chapter 11 Cases. As a result of these renegotiated or rejected contracts, the Company eliminated the majority of its minimum volume commitments as described in Note 16—Commitment and Contingencies— Delivery Commitments in Part II, Item 8. Financial Information of this Annual Report. See this section of the Annual Report for thea description of our transportation and gathering agreements during 2020 and as of our production. Our oil marketer is currently party to a firm transportation agreement that commenced in November 2016 and has a ten-year term with a monthly minimum delivery commitmentDecember 31, 2020.

We amended our agreement with our oil marketer that requires us to sell all of our crude oil from an area of mutual interest in exchange for a make-whole provision that allows us to satisfy any minimum volume commitment deficiencies incurred by our oil marketer with future barrels of crude oil in excess of their minimum volume commitment through October 31, 2018. In December 2017, we extended the term of this agreement through October 31, 2019 and posted a letter of credit in the amount of $35.0 million. We evaluate our contracts for loss contingencies and accrue for such losses, if the loss can be reasonably estimated and deemed probable. We are also subject to a long-term crude oil gathering commitment with an unconsolidated subsidiary, in which we have a minority ownership interest. It has a term of ten years with a minimum volume commitment of an average 9,167 Bbl/d in year one, 17,967 Bbl/d in year two, 18,800 Bbl/d for years three through five and 10,000 Bbl/d for years six through ten.Contents
In collaboration with several other producers and a midstream provider, we have agreed to participate in the expansion of natural gas gathering and processing capacity in the DJ Basin. The plan includes two new processing plants as well as the expansion of a related gathering system, which are currently expected to be completed by mid-2018 and mid-2019, respectively, although the exact start-up dates are undetermined at this time. Our share of these commitments will require 51.5 MMcf and 20.6 MMcf per day, respectively, to be delivered after the plants' in-service dates for a period of seven years thereafter. We may be required to pay a shortfall fee for any volumes under these commitments. These contractual obligations can be reduced by our proportionate share of the collective volumes delivered to the plant by other third party incremental volumes available to the midstream provider at the new facilities that are in excess of the total commitments. We are also required to guarantee a certain target profit margin on these volumes sold for the first three years of each contract. Under our current drilling plans, we expect to meet these volume commitments.
Competition
 
The oil and natural gas industry is intensely competitive, and we compete with other companies that have greater resources than we do. Many of these companies not only explore for and produce oil and natural gas, but also carry on midstream and refining operations and market petroleum and other products on a regional, national or worldwide basis. These companies may be able to pay more for productive oil and natural gas properties and exploratory prospects or to define, evaluate, bid for and purchase a greater number of properties and prospects than our financial or human resources permit. In addition, these companies may have a greater ability to continue exploration activities during periods of low oil, natural gas and NGL market prices. Our larger or more integrated competitors may be able to absorb the burden of existing, and any changes to, federal, state and local laws and regulations more easily than we can, which would adversely affect our competitive position. Our ability to acquire additional properties and to discover reserves in the future will be dependent upon our ability to evaluate and select suitable properties and to consummate transactions in a highly competitive environment. In addition, because we have fewer financial and human resources than many companies in our industry, we may be at a disadvantage in bidding for exploratory prospects and producing oil and natural gas properties.
 
There is also competition between oil and natural gas producers and other industries producing energy and fuel. Furthermore, competitive conditions may be substantially affected by various forms of energy legislation and/or regulation considered from time to time by the governments of the United States and the jurisdictions in which we operate. It is not possible to predict the nature of any such legislation or regulation which may ultimately be adopted or its effects upon our future operations. Such laws and regulations may substantially increase the costs of exploring for, developing or producing oil and natural gas and may prevent or delay the commencement or continuation of a given operation. Our larger competitors may be able to absorb the burden of existing, and any changes to, federal, state and local laws and regulations more easily than we can, which would adversely affect our competitive position.
 
Title to Properties
 
As is customary in the oil and natural gas industry, we initially conduct only a cursory review of the title to our properties in connection with acquisition of leasehold acreage. At such time as we determine to conduct drilling operations on

those properties, we conduct a thorough title examination and perform curative work with respect to significant defects prior to commencement of drilling operations. To the extent title opinions or other investigations reflect title defects on those properties, we are typically responsible for curing any title defects at our expense. We generally will not commence drilling operations on a property until we have cured any material title defects on such property. We have obtained title opinions on substantially all of our producing properties and believe that we have satisfactory title to our producing properties in accordance with standards generally accepted in the oil and natural gas industry.
 
Prior to completing an acquisition of producing oil and natural gas leases, we perform title reviews on the most significant leases and, depending on the materiality of properties, we may obtain a title opinion, obtain an updated title review or opinion or review previously obtained title opinions. Our oil and natural gas properties are subject to customary royalty and other interests, liens for current taxes and other burdens which we believe do not materially interfere with the use of or affect our carrying value of the properties.
 
We believe that we have satisfactory title to all of our material assets. Although title to these properties is subject to encumbrances in some cases, such as customary interests generally retained in connection with the acquisition of real property, customary royalty interests and contract terms and restrictions, liens under operating agreements, liens related to environmental liabilities associated with historical operations, liens for current taxes and other burdens, easements, restrictions and minor encumbrances customary in the oil and natural gas industry, we believe that none of these liens, restrictions, easements, burdens and encumbrances will materially detract from the value of these properties or from our interest in these properties or materially interfere with our use of these properties in the operation of our business. In addition, we believe that we have obtained or have the ability to obtain sufficient rights-of-way grants and permits from public authorities and private parties for us to operate our business in all material respects as described in this Annual Report.
 
Seasonality of Business
 
Weather conditions affect the demand for, and prices of, oil, natural gas and NGL.NGLs. Demand for oil, natural gas and NGLNGLs is typically higher in the fourth and first quarters resulting in higher prices. For example, during February 2021, Extraction’s natural gas revenue was positively impacted by days of severe cold. Due to these seasonal fluctuations, results of operations for individual quarterly periods may not be indicative of the results that may be realized on an annual basis.
 
15

Oil and Gas Leases
 
The typical oil and gas lease agreement covering our properties provides for the payment of royalties to the mineral owner for all oil and gas produced from any wells drilled on the leased premises. Our interest in our properties after lessor royalties and other leasehold burdens is generally 80%approximately 82%. Our working interest for all producing wells averages approximately 71%79% and our net revenue interest is approximately 58%65%.
 
Regulation of the Oil and Gas Industry
 
Our operations are substantially affected by federal, state and local laws and regulations. Failure to comply with applicable laws and regulations can result in substantial penalties. The regulatory burden on the industry increases the cost of doing business and affects profitability. Historically, our compliance costs have not had a material adverse effect on our results of operations; however, we are unable to predict the future costs or impact of compliance. Additional proposals and proceedings that affect the oil and natural gas industry are regularly considered by Congress, the states, the Federal Energy Regulatory Commission (the “FERC”)administrative agencies and the courts. We cannot predict when or whether any such proposals may become effective. WeHowever, we do not believe that we would be affected by any such action materially differently than similarly situated competitors.


Regulation Affecting Production


The production of oil and natural gas is subject to United States federal and state laws and regulations, and orders of regulatory bodies under those laws and regulations, governing a wide variety of matters. All of the jurisdictions in which we own or operate producing oil and natural gas properties have statutory provisions regulating the exploration for and production of oil and natural gas, including provisions related to permits for the drilling of wells, bonding requirements to drill or operate wells, the location of wells, the method of drilling and casing wells, the surface use and restoration of properties upon which wells are drilled, sourcing and disposal of water used in the drilling and completion process, and the abandonment of wells. Our operations are also subject to various conservation laws and regulations. These include the regulation of the size of drilling and spacing units or proration units, the number of wells which may be drilled in an area, and the unitization or pooling of oil or natural gas wells, as well as regulations that generally prohibit the venting or flaring of natural gas, and impose certain requirements regarding the ratability or fair apportionment of production from fields and individual wells. These laws and

regulations may limit the amount of oil and gas we can drill. Moreover, each state generally imposes a production or severance tax with respect to the production and sale of oil, natural gas and NGL within its jurisdiction. States do not regulate wellhead prices or engage in other similar direct regulation, but there can be no assurance that they will not do so in the future. The effect of such future regulations may be to limit the amounts of oil and gas that may be produced from our wells, negatively affect the economics of production from these wells or limit the number of locations we can drill.
 
The failure to comply with the rules and regulations of oil and natural gas production and related operations can result in substantial penalties. Our competitors in the oil and natural gas industry are subject to the same regulatory requirements and restrictions that affect our operations.

Local Regulation

Various local and municipal bodies in each of the states in which we operate have sought to impose prohibitions, moratoria and other restrictions on hydraulic fracturing activities. In Colorado, Senate Bill 19-181 ("SB 19-181"), gives local governmental authorities increased authority to regulate the siting and surface impacts of oil and gas development. We primarily operate in the rural areas of the core Wattenberg Field in Weld County, a jurisdiction in which there has historically been significant support for the oil and gas industry. In Texas, legislation enacted in 2015 generally prohibits political subdivisions from banning, limiting or otherwise regulating oil and gas operations. See Item 1A. Risk Factors-Risks Relating to the Regulatory Environment.
 
Regulation Affecting Sales and Transportation of Commodities
 
Sales prices of gas, oil, condensate and NGL are not currently regulatedrate-regulated and instead are made at market prices. Although prices of these energy commodities are not currently unregulated,rate-regulated, the United States Congress historically has been active in their regulation. We cannot predict whether new legislation to actively regulate, oil and gas, or the prices charged for these commodities might be proposed, what proposals, if any, might actually be enacted by the United States Congress or the various state legislatures and what effect, if any, the proposals might have on our operations. Sales of oil and natural gas may be subject to certain state and federal reporting and compliance requirements.

The pricerates, terms and termsconditions of service of transportation of the commodities, including access to pipeline transportation capacity, are subject to extensive federal and state regulation. Such regulation may affect the marketing of oil and natural gas produced by us, as well as the revenues received for sales of such production. Gathering systems may be subject to state ratable take and common purchaser statutes. Ratable take statutes generally require gatherers to take, without undue discrimination, oil and natural gas production that may be tendered to the gatherer for handling. Similarly, common purchaser statutes generally require gatherers to purchase, or accept for gathering, without undue discrimination as to source of supply or producer. These statutes are designed to prohibit discrimination in favor of one producer over another producer or one source of supply over another source of supply. These statutes may affect whether and to what extent gathering capacity is available for oil and natural gas production, if any, of the drilling program and the cost of such capacity. Further state laws and regulations govern rates and terms of access to intrastate pipeline systems, which may similarly affect market access and cost.
 
The FERCFederal Energy Regulatory Commission (“FERC”) regulates interstate natural gas pipeline transportation rates and terms and conditions of service conditions.under the Natural Gas Act of 1938 (“NGA”). The FERC is continually proposing and implementing new rules and regulations affecting interstate natural gas pipeline transportation. The stated purpose of many of these regulatory changes is to ensure terms and conditions of interstate transportation service are not unduly discriminatory or unduly preferential, to promote competition among the various sectors of the natural gas industry and to promote market transparency. We do not believe that our drilling program will be affected by any such FERC action in a manner materially differently than other similarly situated natural gas producers.
 
In addition to the regulation of interstate natural gas pipeline transportation, the NGA and the Natural Gas Policy Act of 1978 (“NGPA”) provide FERC has jurisdiction over the purchase or sale for resale of gas and the purchase or sale of transportation services subject to FERC’s jurisdiction pursuant toin interstate commerce. In addition, the Energy Policy Act of 2005 (“EPAct 2005”). Under the EPAct 2005, made it is unlawful for “any entity,” including producers such as us, that are otherwise not subject to FERC’s jurisdiction under the Natural Gas Act of 1938 ("NGA"),NGA to use any deceptive or manipulative device or contrivance in connection with the purchase or sale of gas or the purchase or sale of transportation services subject to regulation by FERC, in contravention of rules prescribed by FERC. FERC’s rules implementing this provision make it unlawful, in connection with the purchase or sale of gas subject to theFERC’s jurisdiction of FERC or the purchase or sale of transportation services subject to theFERC’s jurisdiction, of FERC, for any entity, directly or indirectly, to use or employ any device, scheme or artifice to defraud; to make any untrue statement of material fact or omit to make any such statement necessary to make the statements made not misleading; or to engage in any act or practice that operates as a fraud or deceit upon any person. EPAct 2005 also gives FERC authority to impose civil penalties up to approximately $1.2 million per day per violation for violations of the NGA and the Natural Gas Policy Act of 1978 ("NGPA").NGPA. The anti-manipulation rule applies to activities of otherwise non-jurisdictional entities to the extent the activities are conducted “in connection with” gas sales, purchases or transportation subject to FERC jurisdiction, which includes the annual reporting requirements under FERC Order No. 704 (defined below).


In December 2007, FERC issued a final rule on the annual natural gas transaction reporting requirements, as amended by subsequent orders on rehearing (“Order No. 704”). Under Order No. 704, certain market participants, including a producer that engagesproducers engaging in certain wholesale sales or purchases of gas that equal or exceed 2.2 million MMBtus of physical natural gas in the previous calendar year, must annually report such sales and purchases to FERC on Form No. 552 on May 1 of each year. Form No. 552 contains aggregate volumes of natural gas purchased or sold at wholesale in the prior calendar year to the extent such transactions utilize, contribute to, or may contribute to the formation of price indices. Not all types of natural gas sales are

required to be reported on Form No. 552. It is the responsibility of the reporting entity to determine which individual transactions should be reported based on the guidance of Order No. 704. Order No. 704 is intended to increase the transparency of the wholesale gas markets and to assist FERC in monitoring those markets and in detecting market manipulation.
 
The FERC also regulates rates and terms and conditions of service onof interstate transportation of liquids, including oil and NGL, under the Interstate Commerce Act, as it existed on October 1, 1977 (“ICA”). Prices received from the sale of liquids may be affected by the cost of transporting those products to market. The ICA requires that certain interstate liquids pipelines maintain a tariff on file with FERC. The tariff sets forth the established rates as well as the rules and regulations governing the service. The ICA requires, among other things, that rates and terms and conditions of service on interstate common carrier pipelines be “just and reasonable.” Such pipelines must also provide jurisdictional service in a manner that is not unduly discriminatory or unduly preferential. Shippers have the power to challenge new and existing rates and terms and conditions of service before FERC.
 
The rates charged by many interstate liquids pipelines are currently adjusted pursuant to an annual indexing methodology established and regulated by FERC, under which pipelines increase or decrease their rates in accordance with an index adjustment specified by FERC. For the five-year period beginning July 1, 2016, FERC established an annual index adjustment equal to the change in the producer price index for finished goods plus 1.23%. This adjustment is subject to review every five years. Under FERC’s regulations, a liquids pipeline can request a rate increase that exceeds the rate obtained through application of the indexing methodology by obtaining market-based rate authority (demonstrating the pipeline lacks market
17

power), by establishing rates by settlement with all existing shippers, or through a cost-of-service approach (if the pipeline establishes that a substantial divergence exists between the actual costs experienced by the pipeline and the rates resulting from application of the indexing methodology). Increases in liquids transportation rates may result in lower revenue and cash flows for us.
 
In addition, due to common carrier regulatory obligations offor interstate liquids pipelines, capacity must be prorated among shippers in an equitable manner in the event there are nominations in excess of capacity or to accommodate requests for service from new shippers. Therefore, new shippers or increased volume by existing shippers may reduce the capacity available to us. Any prolonged interruption in the operation or curtailment of available capacity of the pipelines that we rely upon for liquids transportation could have a material adverse effect on our business, financial condition, results of operations and cash flows. However, we believe that access to liquids pipeline transportation services generally will be available to us to the same extent as to our similarly situated competitors.
 
Rates for intrastate pipeline transportation of liquids are subject to regulation by state regulatory commissions. The basis for intrastate liquids pipeline regulation, and the degree of regulatory oversight and scrutiny given to intrastate liquids pipeline rates, varies from state to state. We believe that the regulation of liquids pipeline transportation rates will not affect our operations in any way that is materially different from the effects on our similarly situated competitors.
 
In addition to FERC’s regulations, we are required to observe anti-market manipulation laws with regard to our physical sales of energy commodities. In November 2009, the Federal Trade Commission (“FTC”) issued regulations pursuant to the Energy Independence and Security Act of 2007, intended to prohibit market manipulation in the petroleum industry. Violators of the regulations face civil penalties of up to approximately $1.1 million per violation per day. In July 2010, Congress passed the Dodd-Frank Act, which incorporated an expansion ofexpanded the authority of the Commodity Futures Trading Commission (“CFTC”) to prohibit market manipulation in the markets regulated by the CFTC.it regulates. This authority, with respect to oil swaps and futures contracts, is similar to the anti-manipulation authority granted to the FTC with respect to oil purchases and sales. In July 2011, the CFTC issued final rules to implement their new anti-manipulation authority. The rules subject violators to a civil penalty of up to the greater of approximately $1.1 million or triple the monetary gain to the person for each violation.


Some of our pipeline assets and third-party pipelines on which we rely are subject to safety regulation by the U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration (“PHMSA”). In recent years, PHMSA has been active in proposing and finalizing additional regulations for natural gas and hazardous liquids pipelines. In April 2016, PHMSA proposed a rule regarding the safety of natural gas transmission pipelines and gas gathering pipelines in April 2016. In October 2019, PHMSA issued a final rule on the natural gas transmission lines portion of the April 2016 rulemaking, and PHMSA is expected to finalize the rules with respect to gathering lines in 2020. With respect to transmission pipelines, the final rule changes integrity management requirements, expands assessment and repair requirements for pipelines in “moderate-consequence areas,” including areas of medium population density, and increases requirements for monitoring and inspection of pipeline segments not located in “high-consequence areas.” The final rule also requires that records or other data relied on to determine operating pressures must be traceable, verifiable and complete. If the pending gathering-pipeline portion of the rulemaking ultimately includes a final rule that applies similar requirements to gathering lines, some gathering pipeline operators, including us, may be forced to reduce their allowable operating pressures, which would reduce the amount of capacity available to us. As PHMSA has yet to finalize this rulemaking as applied to gathering lines, however, the contents and timing of any final rule are uncertain. Federal and state legislative and regulatory initiatives relating to pipeline safety that require the use of new or more stringent safety controls or result in more stringent enforcement of applicable legal requirements could subject us to increased capital costs, operational delays and costs of operation.

Effective April 2017, PHMSA adopted new rules increasing the maximum administrative civil penalties for violation of the pipeline safety laws and regulations to up to $218,649 per violation per day and up to approximately $2.2 million for a related series of violations.

Regulation of Environmental and Safety and Health Matters


Our operations are subject to numerous stringent and complex federal, state and local laws and regulations governing safety and health aspects of our operations, the release, disposal, or discharge of materials into the environment or otherwise relating to environmental protection. Numerous governmentalGovernmental entities, including the U.S. Environmental Protection Agency (“EPA”), the U.S. Occupational Safety and Health Administration ("OSHA"(“OSHA”) and analogous state agencies, including the COGCC, have the power to enforce compliance with these laws and regulations and the permits issued under them, often requiring difficult and costly actions. These laws and regulations may, among other things (i) require the acquisition of permits to conduct drilling and other regulated activities; (ii) impose limitations on the time, place and manner on drilling and other regulated activities; (iii) restrict the types, quantities and concentration of various materials that may be released into the environment or injected into formations in connection with oil and natural gas drilling and production activities; (iii)(iv) limit or prohibit drilling activities on certain lands lying within wilderness, wetlands and other protected areas; (iv)(v) require remedial

measures to mitigate pollution from former and ongoing operations, such as requirements to close pits and plug abandoned wells; (v)(vi) apply specific health and safety criteria addressing worker protection; and (vi)(vii) impose substantial liabilities for pollution resulting from drilling and production operations. Any failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal penalties, including the assessment of monetary fines or penalties, the imposition of investigatory, remedial or corrective obligations, the occurrence of delays or restrictions in permitting or performance of projects, and the issuance of orders enjoining performance of some or all of our operations in a particular area.
 
These laws and regulations may also restrict the rate of oil and natural gas production below the rate that would otherwise be possible. The regulatory burden on the oil and natural gas industry increases the cost of doing business in the industry and consequently affects profitability. The trend in environmental regulation is to place more restrictions and limitations on activities that may affect the environment, and thus anyAny changes in environmental laws and regulations or re-interpretation of enforcement policies that result in more stringent and costly well drilling, construction, completion or water management activities, or waste handling, storage transport, disposal, or remediation requirements could have a material adverse effect on our financial position and results of operations. We may be unable to pass on such increased compliance costs to our customers. Moreover, accidental spills or releases may occur in the course of our operations and we cannot assure you that we will not incurcan result in the occurrence of significant costs and liabilities, as a result of such spills or releases, including any third-party claims for damage to property, natural resources or persons. Historically, our environmental compliance costs have not had a material adverse effect on our results of operations; however, there can be no assurance that such costs will not be material in the future or that such future compliance will not have a material adverse effect on our business and operating results.


Additionally, on January 29, 2018,In April 2019, SB181 became law, increasing the regulatory authority of local governments in Martinez v. Colorado Oil and Gas Conservation Commission,over the Colorado Supreme Court agreed to review a ruling by the Colorado Courtsurface impacts of Appeals that held that the Colorado Oil & Gas Conservation Commission ("COGCC") had incorrectly concluded that it lacked statutory authority to undertake a proposed rulemaking “to suspend the issuance of permits that allow hydraulic fracturing until it can be done without adversely impacting human health and safety and without impairing Colorado’s atmospheric resource and climate system, water, soil, wildlife, other biological resources.” The Colorado Court of Appeals concluded that Colorado’s Oil and Gas Conservation Act mandated that oil and gas development “be regulated subjectin a necessary and reasonable manner, and in October 2020, Colorado’s AQCC adopted new rules targeting air emissions from upstream oil and gas operation. Among other things, SB181 (i) repeals a prior law restricting local government land use authority over oil and gas mineral extraction areas to areas designated by the COGCC, (ii) directs the AQCC to review its leak detection and repair rules and to adopt rules to minimize emissions of certain air pollutants, (iii) clarifies that local governments have authority to regulate the siting of oil and gas locations in a necessary and reasonable manner, including the ability to inspect oil and gas facilities, impose fines for leaks, spills, and emissions, and impose fees on operators or owners to cover regulation and enforcement costs, (iv) allows local governments or oil and gas operators to request a technical review board to evaluate the effect of the local government’s preliminary or final determination on the operator’s application, (v) repeals an exemption for oil and gas production from counties’ authority to regulate noise, (vi) alters forced pooling requirements by increasing the threshold to compel non-consenting individuals into statutory pooling agreements and (vii) prioritizes the protection of public health, safety, and welfare, including protection of the environment, and wildlife resources.” The Colorado Supreme Court said it would consider whetherresources in the Colorado Courtregulation of Appeals erred in determining that the COGCC misinterpreted the Oil and Gas Conservation Act as “requiring a balance between oil and gas development. Although industry trade associations opposed SB181, Extraction has demonstrated an ability to continue to successfully operate our business. However, the enactment of SB181 and the implementation of related new rules and regulations, which went into effect on January 15, 2021, could lead to delays and additional costs to our business. Also, certain interest groups in Colorado opposed to oil and natural gas development generally have in previous years advanced various alternatives for ballot initiatives which would result in significantly limiting or preventing oil and public health, safety,natural gas development in the state. Various local and welfare.”municipal bodies in Colorado have sought to impose prohibitions, moratoria and other restrictions on hydraulic fracturing activities.

The following is a summary of the more significant existing and proposed environmental and safety and health laws, as amended from time to time, to which our business operations are or may be subject and for which compliance may have a material adverse impact on our capital expenditures, results of operations or financial position.

Hazardous Substances and Wastes
 
The Resource Conservation and Recovery Act (“RCRA”), and comparableanalogous state statutes, regulate the generation, transportation, treatment, storage, disposal and cleanup of hazardous and non-hazardous wastes. Under the guidance issued by the EPA, the individual states administer some or all of the provisions of RCRA, sometimes in conjunction with their own, more stringent requirements. For example, in December 2016, several environmental groups and the EPA entered into a consent decree to address EPA’s alleged failure to timely assess its RCRA Subtitle D criteria regulations exempting certain exploration and production related oil and natural gas wastes from regulation as hazardous wastes under RCRA. In April 2019, the EPA determined in a document entitled “Management of Oil and Gas Exploration, Development and Production Wastes: Factors Informing a Decision on the Need for Regulatory Action” that revisions to these oil and gas waste regulations were not necessary because the main causes for uncontrolled releases of oil and gas waste are appropriately and more readily addressed within the framework of existing state regulatory programs. In the course of our operations, we generate some amounts of ordinary industrial wastes that may be regulated as hazardous wastes. We are required to manage the disposal of hazardous and non-hazardous wastes in compliance with RCRA and analogous state laws. RCRA currently exempts many exploration and production wastes from classification as hazardous waste. Specifically, RCRA excludes from the definition of hazardous waste produced waters and other wastes intrinsically associated with the exploration, development, or production of crude oil and natural gas. However, these oil and gas exploration and production wastes may still be regulated under state solid waste laws and regulations, and it is possible that certain oil and natural gas exploration and production wastes nowcurrently classified as non-hazardous could be classified as hazardous waste in the future. For example, in December 2016, environmental groups and the EPA entered into a consent decree to address EPA's alleged failure to timely assess its RCRA Subtitle D criteria regulations exempting certain exploration and production related oil and natural gas wastes, from regulation as hazardous wastes under RCRA. Under this consent decree, the EPA is required to propose no later than March 15, 2019, a rulemaking for revision of certain Subtitle D criteria regulations pertaining to oil and natural gas wastes or sign a determination that revision of the regulations is not necessary. If EPA proposes a rulemaking for revised oil and natural gas regulations, the consent decree requires that the EPA take final action following notice and comment rulemaking no later than July 15, 2021. Stricter regulation of wastes generated during our or our customer'scustomer’s operations could result in an increase in our and our customer's,customers’, as well as the oil and natural gas exploration and production industry’s,industry’, costs to manage and dispose of wastes, which could have a material adverse effect on our results of operations and financial position.
 

The Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), also known as the Superfund law, and comparable state laws impose joint and several liability, without regard to fault or legality of conduct, on classes of persons who are considered to be responsible for the release of a hazardous substance“hazardous substance” into the environment. These persons include the current and former owners and operators of the site where the release occurred and anyone who disposed or arranged for the transport or disposal of a hazardous substance released at the site. Persons who are or were responsible for releases of hazardous substances under CERCLA and any state analogs may be subject to joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment, for damages to natural resources and for the costs of certain health studies. CERCLA also authorizes the EPA and, in some instances, third parties to act in response to threats to the public health or the environment and to seek to recover from the responsible classes of persons the costs they incur. In addition, it is not uncommon for neighboring landowners and other third-parties to file claims for personal injury and property damage allegedly caused by the hazardous substances released into the environment. We generate materials in the course of our operations that may be regulated as hazardous substances.
 
We currently own, lease, or operate, and in the past have owned, leased or operated, numerous properties that have been used for oil and natural gas exploration, production and processing and other operations for many years. Hazardous substances, wastes, or petroleum hydrocarbons may have been released on, under or from the properties owned, leased or leasedoperated by us, or on, under or from other locations where such substances have been taken for treatment or disposal. In addition, some of our properties have been operated by third parties or by previous owners or operators whose treatment and disposal of substances, including hazardous substances, wastes, or petroleum hydrocarbons, was not under our control. These properties and the hazardous substances, wastes or petroleum hydrocarbons disposed or released on them may be subject to CERCLA, RCRA and analogous state laws. Under such laws, we could be required to remove previously disposed substances and wastes, remediate contaminated property, or perform remedial operations to prevent future contamination, the costs of which could have a material adverse effect on our business and results of operations.
 
Water Discharges
 
The Federal Water Pollution Control Act, also known as the Clean Water Act (“CWA”), and analogous state laws, impose restrictions and strict controls with respect to the discharge of pollutants, including spills and leaks of oil and other hazardous substances, into state waters and waters of the United States. The discharge of pollutants into regulated waters, including jurisdictional wetlands, is prohibited, except in accordance with the terms of a permit issued by the EPA or an analogous state agency. Spill prevention, control and countermeasure requirements of federal laws require appropriate containment berms and similar structures to help prevent the contamination of navigable waters by a petroleum hydrocarbon tank spill, rupture or leak. In addition, the CWA and analogous state laws require individual permits or coverage under general permits for discharges of storm water runoff from certain types of facilities. The CWA also prohibits the discharge of dredge and fill material in regulated waters, including wetlands, unless authorized by permit. In June 2015, the EPA and the U.S. Army Corps of Engineers ("Corps"(“Corps”) published a final rule to revise the definition of "waters“waters of the United States" ("WOTUS"States” (“WOTUS”) for all Clean Water Act
20

CWA programs, but legal challenges to this rule followed and the rule was stayed nationwide by the U.S. Sixth Circuit Court of Appeals in October 2015. In response to this decision, the EPA and the Corps resumed nationwide use of the agencies' prior regulations defining the term "waters of the United States." However, in January 2018, the U.S. Supreme Court ruled that the rule revising the WOTUS definition must first be reviewed in the federal districtcourts,district courts, which could resultresulted in a withdrawal of the stay by the Sixth Circuit. Subsequent litigation in the federal district courts resulted in patchwork application of the rule in some states (e.g., California, Oklahoma), but not others (e.g. Colorado). In addition,July 2017, the EPA has issued proposalsproposed to repeal the 2015 rule revising the WOTUS definition and, in December 2018, EPA and the Corps issued a proposed rule revising the WOTUS definition that would provide discrete categories of jurisdictional waters and tests for determining whether a particular water body meets any of those classifications. In October 2019, the EPA issued a final rule repealing the 2015 rule (which became effective in December 2019 and has already been challenged in federal district courts in New Mexico, New York, and South Carolina). In January 2020, the EPA announced a final rule redefining the WOTUS definition. Several groups have already announced their intentions to delay its implementation until 2020 to allow time for EPA to reconsiderchallenge the definition of the term "waters of the United States."final revision rule. To the extent thisthe repeal and revision rules are successfully challenged and the 2015 rule is enforced in jurisdictions in which we operate or a revisedreplacement rule expands the scope of the CWA'sCWA’ jurisdiction, we could face increased costs and delays with respect to obtaining permits for dredge and fill activities in wetland areas in connection with any expansion activities. Federal and state regulatory agencies may impose substantial administrative, civil and criminal penalties as well as other enforcement mechanisms for non-compliance with discharge permits or other requirements of the CWA and analogous state laws and regulations, including spills and other non-authorized discharges.
 
The Oil Pollution Act of 1990 (“OPA”), amends the CWA and sets minimum standards for prevention, containment and cleanup of oil spills. The OPA applies to vessels, offshore facilities, and onshore facilities, including exploration and production facilities that may affect waters of the United States. Under OPA, responsible parties, including owners and operators of onshore facilities, may be held strictly liable for oil cleanup costs and natural resource damages as well as a variety of public and private damages that may result from oil spills. The OPA also requires owners or operators of certain onshore facilities to prepare Facility Response Plans for responding to a worst-case discharge of oil into waters of the United States.


Subsurface Injections
 
In the course of our operations, we produce water in addition to oil and natural gas. Water that is not recycled may be disposed of in disposal wells, which inject the produced water into non-producing subsurface formations. Underground

injection operations are regulated pursuant to the Underground Injection Control (“UIC”) program established under the Safe Drinking Water Act (“SDWA”) and analogous state laws. The UIC program requires permits from the EPA or an analogous state agency for the construction and operation of disposal wells, establishes minimum standards for disposal well operations, and restricts the types and quantities of fluids that may be disposed. A change in UIC disposal well regulations or the inability to obtain permits for new disposal wells in the future may affect our ability to dispose of produced water and ultimately increase the cost of our operations. For example, in response to recent seismic events near belowground disposal wells used for the injection of oil and natural gas-related wastewaters, regulators in some states, including Colorado, have imposed more stringent permitting and operating requirements for produced water disposal wells. In Colorado, permit applications are reviewed specifically to evaluate seismic activity and, as of 2011, the state has required operators to identify potential faults near proposed wells, if earthquakes historically occurred in the area, and to accept maximum injection pressures and volumes based on fracture gradient as conditions to permit approval. Additionally, legal disputes may arise based on allegations that disposal well operations have caused damage to neighboring properties or otherwise violated state or federal rules regulating waste disposal. These developments could result in additional regulation, restriction on the use of injection wells by us or by commercial disposal well vendors whom we may use from time to time to dispose of wastewater, and increased costs of compliance, which could have a material adverse effect on our capital expenditures and operating costs, financial condition, and results of operations.

Air Emissions

The Clean Air Act (the “CAA”) and comparable state laws restrict the emission of air pollutants from many sources, such as, for example, tank batteries and compressor stations, through air emissions standards, construction and operating permitting programs and the imposition of other compliance standards. These laws and regulations may require us to obtain pre-approval for the construction or modification of certain projects or facilities expected to produce or significantly increase air emissions, obtain and strictly comply with stringent air permit requirements or utilize specific equipment or technologies to control emissions of certain pollutants. The need to obtain permits has the potential to delay the development of oil and natural gas projects. Over the next several years, we may be charged royalties on natural gas losses or required to incur certain capital expenditures for air pollution control equipment or other air emissions related issues. For example, in October 2015,2016, EPA designated the EPA issued a final rule underDenver Metro North Front Range as Marginal non-attainment for the CAA, lowering the2008 National Ambient Air Quality Standard (“NAAQS”) for ground-levelozone. In August 2019, the EPA proposed to reclassify the Denver Metro North Front Range area as a serious non-attainment area for ozone from 75 parts per billion (“ppb”)due to high levels detected in 2016 and 2017. The proposal would set a new deadline of July 20, 2021 for the 8-hour primary and secondaryDenver area to attain the 2008 ozone standards to 70 ppb for both standards. On June 6, 2017, EPA extended the deadline for promulgating initial area designations by one year.standard. Reclassification of areas or imposition of more stringent standards
21

(including a lowering of the major source threshold for volatile organic compounds and oxides of nitrogen and the resulting increased likelihood that a source may be subject to Non-Attainment New Source Review) may make it more difficult to construct new or modified sources of air pollution in newly designated non-attainment areas. Also, states are expected to implement more stringent requirements as a result of this new final rule, which could apply to our operations. In addition, during the fall of 2016, EPA also issued final Control Techniques Guidelines (“CTGs”) for reducing volatile organic compound emissions from existing oil and natural gas equipment and processes in ozone non-attainment areas, including the Denver Metro North Front Range Ozone 8-hour Non-Attainment area. In 2017, as part of the federal CTG process for oil and natural gas, Colorado beganundertook a stakeholder and rulemaking effort to compare the CTGs to existing Colorado requirements to ensure they meet applicable federal requirements. This process could resultrequirements, which resulted in revisions to Colorado’ Regulation Number 7. The new orstate regulations include more stringent air quality control requirements applicable to our operations. In another example, in June 2016, the EPA finalized a revised rule regarding criteria for aggregating multiple small surface sites into a single source for air-quality permitting purposes applicable to the oil and gas industry. This rule could cause small facilities, on an aggregate basis, to be deemed a major source, thereby triggering more stringent permitting requirements. Compliance with these or other air pollution control and permitting requirements have the potential to delay the development of oil and natural gas projects and increase our costs of development and production, which costs could have a material adverse impact on our business and results of operations.
 
Regulation of Greenhouse Gas (“GHG”) Emissions
 
Climate change continues to attract considerable public and scientific attention. As a result, numerous proposals have been made and could continue to be made at the international, national, regional and state levels of government to monitor and limit emissions of GHG. These efforts have included consideration of cap-and-trade programs, carbon taxes, GHG reporting and tracking programs, and regulations that directly limit GHG emissions from certain sources. At the federal level, no comprehensive climate change legislation has been implemented to date. However, the EPA has adopted rules under authority of the CAA that, among other things, establish Potential for Significant Deterioration ("PSD"(“PSD”) construction and Title V operations permit reviews for GHG emissions from certain large stationary sources that are also potential major sources of certain principal pollutant emissions, which reviews could require meeting “best available control technology” standards for those emissions. In addition, the EPA has adopted rules requiring the monitoring and annual reporting of GHG emissions from certain petroleum and natural gas system sources in the United States, including, among other things, onshore producing facilities, which include certain of our operations.
 

Federal agencies also have begun directly regulating emissions of methane, a GHG, from oil and natural gas operations. In June 2016, the EPA published the New Source Performance Standards (“NSPS”) Subpart OOOOa standards that require certain new, modified or reconstructed facilities in the oil and natural gas sector to reduce these methane gas and volatile organic compound emissions. These SubpartHowever, in September 2019, under the new administration, EPA proposed to remove transmission and storage activities from the purview of the OOOOa standards, will expand previously issued NSPS published bythereby rescinding the EPA in 2012VOC and known as Subpart OOOO, by using certain equipment-specificmethane emissions control practices. However, in April 2017,limits applicable to those activities. The proposed rule would also rescind the EPA announced that itmethane limit emissions for production and processing sources, but would review this methane rulemaintain emissions limits for new, modified and reconstructed sources and initiated reconsideration proceedings to potentially revise or rescind portions ofVOCs. In the rule. In June 2017,alternative, the EPA also proposed a two-year stay of certain requirements ofto simply rescind the methane rule pendingrequirements for all oil and natural gas sources, without removing any activities from the reconsideration proceedings; however, the rule remains in effect in the meantime.source category. Similarly, in November 2016,September 2018, the federal Bureau of Land Management ("BLM"(“BLM”) issued a final rule that relaxes or rescinds certain requirements of its November 2016 rule enacted to reduce methane emissions by regulating venting, flaring, and leaks from oil and gas operations on federal and American Indian lands. However,California and New Mexico have challenged the rule in December 2017, BLM finalizedongoing litigation. In addition, in April 2018, a suspensioncoalition of certain requirementsstates filed a lawsuit aiming to force EPA to establish guidelines for limiting methane emissions from existing sources in the oil and natural gas section; that lawsuit is currently pending (as of October 2019, the EPA had requested a stay of the rule until 2019. That suspension is now being challenged in court, and substantial uncertainty exists with respect to implementationlitigation pending the outcome of its proposed overhaul of the rule.2016 methane requirements).

On the international level, in December 2015, the United States joined the international community at the 21st Conference of the Parties of the United Nations Framework Convention on Climate Change in Paris, France that prepared an agreement requiring member countries to review and “represent a progression” in their intended nationally determined contributions, which set GHG emission reduction goals every five years beginning in 2020. This “Paris Agreement” was signed by the United States in April 2016 and entered into force in November 2016; however, this agreement does not create any binding obligations for nations to limit their GHG emissions, but rather includes pledges to voluntarily limit or reduce future emissions. In follow-up to an earlier announcement by President Trump, in August 2017, the U.S. Department of State officially informed the United Nations of the intent of the United States to withdraw from the Paris Agreement. The Paris Agreement provides for a four-year exit process beginning when it took effect inand on November 2016, which would result in an effective exit date4, 2019, the U.S. submitted formal notification of November 2020. The United States’ adherenceits withdrawal to the exit process and/orUnited Nations. However, during the terms on whichfirst part of 2021, the United States, may re-enterunder a new presidential administration, rejoined the Paris Agreement or a separately negotiated agreement are unclear at this time.Agreement.

The adoption and implementation of any international, federal or state legislation or regulations that require reporting of GHG or otherwise limit emissions of GHG from our equipment and operations could result in increased costs to reduce emissions of GHG associated with our operations as well as delays or restrictions in our ability to permit GHG emissions from new or modified sources. In addition, substantial limitations on GHG emissions could adversely affect demand for the oil, natural gas and NGL we produce and lower the value of our reserves, which devaluation could be significant. One or more of these developments could have a materially adverse effect on our business, financial condition and results of operations. Additionally, it should be noted that increasing concentrations of GHG in the Earth’s atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, floods and other climatic events; if any such effects were to occur, they could have an adverse effect on our exploration and production operations. At this time, we have not developed a comprehensive plan to address the legal, economic, social or physical impacts of climate change on our operations. Finally, notwithstanding potential risks related to climate change, the International Energy Agency, an autonomous intergovernmental organization involved in international energy policy, estimates that global energy demand will continue to rise and will not peak until after 2040 and oil and gas will continue to represent a substantial percentage of global energy use over that time. However, recent activism directed at shifting funding away from companies with energy-related assets could result in limitations or restrictions on certain sources of funding for the energy sector.
 
Hydraulic Fracturing Activities
 
Hydraulic fracturing is an important and common practice that is used to stimulate production of natural gas and oil from dense subsurface rock formations. We regularly use hydraulic fracturing as part of our operations. Hydraulic fracturing involves the injection of water, sand or alternative proppant and chemical additives under pressure into targeted geological formations to fracture the surrounding rock and stimulate production. Hydraulic fracturing is typically regulated by state oil and natural gas commissions or similar state agencies. However, several federal agencies have conducted investigations or asserted regulatory authority over certain aspects of the process. For example, in December 2016, the EPA released its final report on the potential impacts of hydraulic fracturing on drinking water resources, concluding that “water cycle” activities associated with hydraulic fracturing may impact drinking water resources under certain circumstances. Additionally, in June 2016 the EPA published in June 2016 anfinal effluent limitations guideline final ruleguidelines pursuant to its authority under the SDWA prohibiting the discharge of wastewater from onshore unconventional oil and natural gas extraction facilities to publicly owned wastewater treatment plants; asserted regulatory authority in 2014 under the SDWA over hydraulic fracturing activities involving the use of diesel and issued guidance covering such activities; and issued in 2014 a prepublication of its Advance Notice of Proposed Rulemaking regarding Toxic Substances Control Act reporting of the chemical substances and mixtures used in hydraulic fracturing. Also, the BLM published a final rule in March 2015 establishing new or more stringent standards for performing hydraulic fracturing on federal and American Indian lands including well casing and wastewater storage requirements and an obligation for exploration and production operators to disclose what chemicals they are using in fracturing activities. However,

followingFollowing years of litigation, the BLM rescinded the rule in December 2017.2017; however, that rescission has been challenged by several environmental groups and states in ongoing litigation (oral arguments were heard in the case in January 2020 after a long hiatus). Also, from time to time, legislation has been introduced, but not enacted, in Congress to provide for federal regulation of hydraulic fracturing and to require disclosure of the chemicals used in the fracturing process. In the event that a new, federal level of legal restrictions relating to the hydraulic fracturing process is adopted in areas where we operate, we may incur additional costs to comply with such federal requirements that may be significant in nature, and also could become subject to additional permitting requirements and experience added delays or curtailment in the pursuit of exploration, development, or production activities.
 
AtColorado developed significant new oil and gas related rules regulating siting of oil and gas facilities and the permitting process including, but not limited to 2,000-foot setbacks from all schools and childcare facilities, and the establishment of new siting zones, which require enhanced review criteria and other requirements for permitting. These new rules went into effect on January 15, 2021. The enactment of SB181 in April 2019 increased local control and elevated public health, safety and environmental concerns in the regulation of oil and gas development in the state. This legislation also explicitly authorized cities and counties in the state level, Colorado, where we conduct operations, is among the states that has adopted,to develop and other states are considering adopting, regulations that could impose new or more stringent permitting, disclosure or well-construction requirements on hydraulic fracturing operations. Moreover, states could elect to prohibit high volume hydraulic fracturing altogether, following the approach taken by the State of New York in 2015.implement local-level oil and gas regulations. Also, certain interest groups in Colorado opposed to oil and natural gas development generally, and hydraulic fracturing in particular, have from time to time advanced various options for ballot initiatives (including proposed ballot initiatives for 2022 that, if approved, would allow revisions to the state constitution in a manner that would make such exploration and production activities in the state more difficult in the future. However, during the November 2016 voting process, one proposed amendment placed on the Colorado state ballot making it relatively more difficult to place an initiative on the state ballot was passed by the voters. As a result, there are more stringent procedures now in place for placing an initiative on a state ballot. In addition to state laws, local land use restrictions may restrict drilling or the hydraulic fracturing process and cities may adopt local ordinances allowing hydraulic fracturing activities within their jurisdictions but regulating the time, place and manner of those activities. If new or more stringent federal, state or local legal restrictions relating to the hydraulic fracturing process are adopted in areas where we operate, including, for example, on federal and American Indian lands, we could incur potentially significant added cost to comply with such requirements, experience delays or curtailment in the pursuit of exploration, development or production activities, and perhaps even be precluded from drilling wells.

In the event that local or state restrictions or prohibitions are adopted in areas where we conduct operations, including the DJ Basin in Colorado, that impose more stringent limitations on the production and development of oil and natural gas,
23

including, among other things, the development of increased setback distances, we and similarly situated oil and natural exploration and production operators in the state may incur significant costs to comply with such requirements or may experience delays or curtailment in the pursuit of exploration, development, or production activities, and possibly be limited or precluded in the drilling of wells or in the amounts that we and similarly situated operates are ultimately able to produce from our reserves. Any such increased costs, delays, cessations, restrictions or prohibitions could have a material adverse effect on our business, prospects, results of operations, financial condition, and liquidity. If new or more stringent federal, state or local legal restrictions relating to the hydraulic fracturing process are adopted in areas where we operate, including, for example, on federal and American Indian lands, we could incur potentially significant added cost to comply with such requirements, experience delays or curtailment in the pursuit of exploration, development or production activities, and perhaps even be precluded from drilling wells.
 
Moreover, because most of our operations are conducted in a particular area, the DJ Basin in Colorado, legal restrictions imposed in that area will have a significantly greater adverse effect than if we had our operations spread out amongst several diverse geographic areas. Consequently, in the event that local or state restrictions or prohibitions are adopted in the DJ Basin in Colorado that impose more stringent limitations on the production and development of oil and natural gas, we may incur significant costs to comply with such requirements or may experience delays or curtailment in the pursuit of exploration, development, or production activities, and possibly be limited or precluded in the drilling of wells or in the amounts that we are ultimately able to produce from our reserves. Any such increased costs, delays, cessations, restrictions or prohibitions could have a material adverse effect on our business, prospects, results of operations, financial condition, and liquidity.


Activities on Federal Lands


Oil and natural gas exploration, development and production activities on federal lands, including American Indian lands and lands administered by the BLM, are subject to the National Environmental Policy Act (“NEPA”). NEPA requires federal agencies, including the BLM, to evaluate major agency actions having the potential to significantly impact the environment. In the course of such evaluations, an agency will prepare an Environmental Assessment that assesses the potential direct, indirect and cumulative impacts of a proposed project and, if necessary, will prepare a more detailed Environmental Impact Statement that may be made available for public review and comment. While we currently have minimal exploration, development and production activities on federal lands, our proposed exploration, development and production activities are expected to include leasing of federal mineral interests, which will require the acquisition of governmental permits or authorizations that are subject to the requirements of NEPA. This process has the potential to delay or limit, or increase the cost of, the development of oil and natural gas projects. Authorizations under NEPA are also subject to protest, appeal or litigation,

any or all of which may delay or halt projects. Moreover, depending on the mitigation strategies recommended in Environmental Assessments or Environmental Impact Statements, we could incur added costs, which may be substantial. In January 2020, the White House Council on Environmental Quality (“CEQ”) proposed changes to NEPA regulations designed to overhaul the system and speed up federal agencies’ approval of projects. Among other things, the rule proposes to narrow the definition of “effects” to exclude the terms “direct,” “indirect,” and “cumulative” and redefine the term to be “reasonably foreseeable” and having “a reasonably close causal relationship to the proposed action or alternatives.” Changes to the NEPA regulations could have an effect on our operations and our ability to obtain governmental permits. We continuously evaluate the effect of new rules on our business.
 
Endangered Species and Migratory Birds Considerations
 
The federal Endangered Species Act (“ESA”), and comparable state laws were established to protect endangered and threatened species. Pursuant to the ESA, if a species is listed as threatened or endangered, restrictions may be imposed on activities adversely affecting that species or that species’ habitat. Similar protections are offered to migrating birds under the Migratory Bird Treaty Act. We may conduct operations on oil and natural gas leases in areas where certain species that are listed as threatened or endangered are known to exist and where other species such as the sage grouse, that potentially could be listed as threatened or endangered under the ESA may exist. Moreover, as a result of one or more agreements entered into by the U.S. Fish and Wildlife Service, the agency is required to make a determination on listing of numerous species as endangered or threatened under the ESA pursuant to specific timelines. The identification or designation of previously unprotected species as threatened or endangered in areas where underlying propertyour operations are conducted could cause us to incur increased costs arising from species protection measures, time delays or limitations on our exploration and production activities that could have an adverse impact on our ability to develop and produce reserves. If we were to have a portion of our leases designated as critical or suitable habitat, it could adversely impact the value of our leases.

Employee Safety and Health
 
We are subject to the requirements of the Occupational Safety and Health Act and comparable state statutes whose purpose is to protect the health and safety of workers. In addition, OSHA'sOSHA’s hazard communication standard, the Emergency Planning and Community Right-To-Know Act and comparable state statutes and any implementing regulations require that we organizemaintain and/or disclose information about hazardous materials used or produced in our operations and that this information be provided to employees, state and local governmental authorities and citizens. For example, under a new OSHA standard limiting respirable silica exposure, the oil and gas industry must implement engineering controls and work practices to limit exposures below the new limits by June 2021. Failure to comply with OSHA requirements can lead to the imposition of penalties.
 
Related Permits and Authorizations
 
Many environmental laws require us to obtain permits or other authorizations from state and/or federal agencies before initiating certain drilling, construction, production, operation, or other oil and natural gas activities, and to maintain these permits and compliance with their requirements for on-going operations. These permits are generally subject to protest, appeal, or litigation, which can in certain cases delay or halt projects and cease production or operation of wells, pipelines, and other operations.
 
Related Insurance
 
We maintain insurance against some risks associated with above or underground contamination that may occur as a result of our exploration and production activities. However, this insurance is limited to activities at the well site and there can be no assurance that this insurance will continue to be commercially available or that this insurance will be available at premium levels that justify its purchase by us. The occurrence of a significant event that is not fully insured or indemnified against could have a materially adverse effect on our financial condition and operations. Further, we have no coverage for gradual, long-term pollution events.
 
Employees
 
As of December 31, 2017,2020, we employed 227125 people. We are not a party to any collective bargaining agreements and have not experienced any strikes or work stoppages. We consider our relations with our employees to be satisfactory.
From time to time we utilize the services of independent contractors to perform various field and other services.
 
Facilities
 
Our corporate headquarters is located in Denver, Colorado. We maintain a field office in Windsor, Colorado.

ITEM 1A.RISK FACTORS
 
RISK FACTORS
There are many factors that may affect our business and results of operations. If any of the following risks actually occur, our business, financial condition and results of operations could be materially and adversely affected and we may not be able to achieve our goals. We cannot assure you that any of the events discussed in the risk factors below will not occur. Further, the risks and uncertainties described below are not the only ones we face. Additional risks not presently known to us or that we currently deem immaterial may also materially affect our business.
Summary of Material Risks Related to the Oil, Natural Gas and NGL Industry and Our Business
Risks Relating to Commodity Prices
Oil and natural gas prices are volatile. An extended or further decline in commodity prices may adversely affect our business, financial condition or results of operations and our ability to meet our capital expenditure obligations and financial commitments.
Risks Relating to our Reserves and Reserve Estimation
Reserve estimates depend on many assumptions that may turn out to be inaccurate. Any material inaccuracies in reserve estimates or underlying assumptions will materially affect the quantities and present value of our reserves.
There is a limited amount of production data from horizontal wells completed in the DJ Basin. As a result, reserve estimates associated with horizontal wells in this area are subject to greater uncertainty than estimates associated with reserves attributable to vertical wells in the same area.
Unless we replace our reserves with new reserves and develop those reserves, our reserves and production will decline, which would adversely affect our future cash flows and results of operations.
A substantial portion of our reserves are located in urban areas, which could increase our costs of development and delay production.
Risks Related to our Operations
Drilling for and producing oil and natural gas are high risk activities with many uncertainties that could adversely affect our business, financial condition or results of operations.
Properties that we decide to drill may not yield oil, natural gas or NGL in commercially viable quantities.
Our undeveloped acreage must be drilled before lease expiration to hold the acreage by production. In highly competitive markets for acreage, failure to drill sufficient wells to hold acreage could result in a substantial lease renewal cost or, if renewal is not feasible, loss of our lease and prospective drilling opportunities.
Substantially all of our producing properties are located in the DJ Basin of Colorado, making us vulnerable to risks associated with operating in one major geographic area. Specifically, as the DJ Basin is an area of high industry activity, we may be unable to hire, train or retain qualified personnel needed to manage and operate our assets.
Risks Related to the Regulatory Environment
Changes in the legal and regulatory environment governing the oil and natural gas industry, particularly changes specific to the DJ Basin of Colorado, could have a material adverse effect on our business.
Risks Related to Capital
Our exploration and development projects require substantial capital expenditures. We may be unable to obtain required capital or financing on satisfactory terms, which could lead to a decline in our reserves.
A negative shift in investor sentiment of the oil and gas industry could have adverse effects on our ability to raise debt and equity capital and on our operations.
26

Declining general economic, business or industry conditions may have a material adverse effect on our results of operations, liquidity and financial condition.
We may be unable to access the equity or debt capital markets, including the market for senior unsecured notes, to meet our obligations.
Risks Related to Debt
The borrowing base under our RBL Credit Facility may be reduced in connection with declines in commodity prices, which could hinder or prevent us from meeting our future capital needs.
We may not be able to generate sufficient cash to service all of our indebtedness and may be forced to take other actions to satisfy our obligations under our debt arrangements, which may not be successful.
Risks Related to Common Stock
The market price of our securities is subject to volatility.
Risks Related to Taxes
Recent changes in United States federal income tax law may have an adverse effect on our cash flows, results of operations or financial condition overall.
Certain United States federal income tax deductions currently available with respect to natural gas and oil exploration and development may be eliminated as a result of future legislation.
Our ability to use our net operating loss carryforwards (“NOLs”) and other tax attributes may be limited.
Risks Related to Technology
Conservation measures and technological advances could reduce demand for oil, natural gas and NGL.
Risks Related to the General Business
Properties we acquire may not produce as projected, and we may be unable to determine reserve potential, identify liabilities associated with the properties that we acquire or obtain protection from sellers against such liabilities.
We may be unable to make accretive acquisitions or successfully integrate acquired businesses or assets, and any inability to do so may disrupt our business and hinder our ability to grow.
Our cash flow from operations and access to capital are subject to a number of variables.
We depend upon several significant purchasers for the sale of most of our oil and natural gas production. The loss of one or more of these purchasers could, among other factors, limit our access to suitable markets for the oil, natural gas and NGL we produce.
The inability of one or more of our purchasers to meet their obligations may adversely affect our financial results.
Risks Related to the COVID-19 Pandemic
The ongoing COVID-19 pandemic and the effects of actions by, or disputes among or between, oil and natural gas producing countries may result in transportation and storage constraints, reduced production and shut-in of our wells, any of which would adversely affect our business, financial condition and results of operations.
Risks Related to Bankruptcy
We recently emerged from bankruptcy, which may adversely affect our business and relationships.
We may be negatively impacted by litigation and legal proceedings, including ongoing claims in connection with the Chapter 11 Cases.

Detailed Discussion of Risks Related to the Oil, Natural Gas and NGL Industry and Our Business
Risks Relating to Commodity Prices
Oil and natural gas prices are volatile. An extended or further decline in commodity prices may adversely affect our business, financial condition or results of operations and our ability to meet our capital expenditure obligations and financial commitments.
The prices we receive for our oil, natural gas and NGL production heavily influence our revenue, profitability, access to capital and future rate of growth. Oil, natural gas and NGL are commodities and, therefore, their prices are subject to wide fluctuations in response to relatively minor changes in supply and demand. Historically, theThe commodities market has historically been volatile. For example, during the period from January 1, 2014 to December 31, 2017, NYMEX West Texas Intermediate oil prices ranged from a high of $107.26 per Bbl to a low of $26.21 per Bbl. Average daily prices for NYMEX Henry Hub gas ranged from a high of $6.15 per MMBtu to a low of $1.64 per MMBtu during the same period. The duration and magnitude of the recent decline in oil prices cannot be predicted. This market will likely continue to be volatile in the future.volatile. The prices we receive for our production, and the levels of our production, depend on numerous factors beyond our control. TheseThe prices we receive for our production depend on numerous factors includebeyond our control, including, but not limited to, the following:
worldwide and regional economic conditions impacting the global supply and demand for oil, natural gas and NGL;
the price and quantity of foreign imports;
political conditions in or affecting other producing countries, including conflicts in the Middle East, Africa, South America and Russia;
the level of global exploration and production;
the level of global inventories;
prevailing prices on local price indices in the areas in which we operate;
the proximity, capacity, cost and availability of gathering and transportation facilities;
localized and global supply and demand fundamentals and transportation availability;
the extent to which members of the Organization of Petroleum Exporting CountriesOPEC and other oil exporting nations to agree to and maintain oil price and production controls;
weather conditions;
technological advances affecting energy consumption;
the effect of worldwide energy conservation and environmental protection efforts;
the price and availability of alternative fuels;
domestic, local and foreign governmental regulation and taxes; and
shareholder activism and activities by non-governmental organizations to restrict the exploration, development and production of oil and natural gas.gas; and

Since November 2014, prices for U.S. oil have weakened in response to continued high levels of production, a buildup in inventories and lower global demand. Pricesor national health epidemics or concerns, such as the ongoing coronavirus outbreak, which may reduce demand for oil, have showed some recovery beginning in late 2016natural gas and continuing into 2018, but remain significantly below 2014 levels.related products because of reduced global or national economic activity.

Lower commodity prices will reduce our cash flows and borrowing ability. We may be unable to obtain needed capital or financing on satisfactory terms, which could lead to a decline in the present value of our reserves and our ability to develop future reserves. Lower commodity prices may also reduce the amount of oil, natural gas and NGL that we can produce

economically and may impact our ability to satisfy our obligations under firm-commitment transportation agreements. We have historically been able to hedge our oil and natural gas production at prices that are significantly higher than current strip prices. However, in the current commodity price environment, our ability to enter into comparable derivative arrangements may be limited, and we are not under an obligationlimited. The RBL Credit Agreement requires us to hedgemaintain commodity hedges covering a specific portionminimum of 65% of our anticipated oil or naturaland gas production.production from PDP reserves for the succeeding twelve months and 50% of our anticipated oil and gas production from PDP reserves for the next succeeding twelve months.
Using lower prices in estimating proved reserves would likely result in a reduction in proved reserve volumes due to economic limits. While it is difficult to project future economic conditions and whether such conditions will result in impairment of proved property costs, we consider several variables including specific market factors and circumstances at the time of prospective impairment reviews, and the continuing evaluation of development plans, production data, economics and other factors. In addition, sustained periods with oil and natural gas prices at levels lower than current West Texas Intermediate strip prices and the resultant effect such prices may have on our drilling economics and our ability to raise capital may require us to re-evaluate and postpone or eliminate our development drilling, which could result in the reduction of some of our proved undeveloped reserves and related standardized measure. If we are required to curtail our drilling program, we may be unable to continue to hold leases that are scheduled to expire, which may further reduce our reserves. As a result, a substantial or extended decline in commodity prices may materially and adversely affect our future business, financial condition, results of operations, liquidity or ability to finance planned capital expenditures.
Our development
28

The prices we receive for our production may be affected by local and exploratory drilling efforts andregional factors.
The prices we receive for our well operations may not be profitable or achieve our targeted returns.
We have acquired significant amounts of unproved property in order to further our development efforts and expect to continue to undertake acquisitions in the future. Development and exploratory drilling and production activities are subject to many risks, including the risk that no commercially productive reservoirs will be discovered. We acquire unproved propertiesdetermined to a significant extent by factors affecting the local and lease undeveloped acreage that we believe will enhance our growth potentialregional supply of and increase our results of operations over time. However, we cannot assure you that all prospects will be economically viable or that we will not abandon our investments. Additionally, we cannot assure you that unproved property acquired by us or undeveloped acreage leased by us will be profitably developed, that wells drilled by us in prospects that we pursue will be productive or that we will recover all or any portion of our investment in such unproved property or wells.
Properties we acquire may not produce as projected, and we may be unable to determine reserve potential, identify liabilities associated with the properties that we acquire or obtain protection from sellers against such liabilities.
Acquiringdemand for oil and natural gas, properties requires us to assess reservoirincluding the adequacy of the pipeline and processing infrastructure characteristics, including recoverable reserves, development and operating costs and potential liabilities, including environmental liabilities. Such assessments are inexact and inherently uncertain. For these reasons, the properties we have acquired or will acquire in the region to process, and transport, our production and that of other producers. Those factors result in basis differentials between the published indices generally used to establish the price received for regional oil and natural gas production and the actual price we receive for our production, which may be lower than index prices. If the price differentials pursuant to which our production is subject were to widen due to oversupply or other factors, our revenue could be negatively impacted.
The ability or willingness of OPEC and other oil exporting nations to set and maintain production levels has a significant impact on oil and natural gas commodity prices.

OPEC is an intergovernmental organization that seeks to manage the price and supply of oil on the global energy market. Actions taken by OPEC members, including those taken alongside other oil exporting nations, have a significant impact on global oil supply and pricing. For example, OPEC and certain other oil exporting nations have previously agreed to take measures, including production cuts, to support crude oil prices. In March 2020, members of OPEC and Russia considered extending and potentially increasing these oil production cuts. However, those negotiations were unsuccessful. As a result, Saudi Arabia announced an immediate reduction in export prices and Russia announced that all previously agreed upon oil production cuts would expire on April 1, 2020. These actions led to an immediate and steep decrease in oil prices, which reached a closing NYMEX price low of under negative $37.00 per Bbl of crude oil in April 2020. Although OPEC members subsequently agreed on certain production cuts beginning in May 2020 and continuing through April 2022, there can be no assurance that OPEC members and other oil exporting nations will continue to agree to future mayproduction cuts or other actions to support and stabilize oil prices, nor can there be any assurance that they will not produce as projected. In connection withfurther reduce oil prices or increase production. Uncertainty regarding future actions to be taken by OPEC members or other oil exporting countries could lead to increased volatility in the assessments,price of oil, which could adversely affect our business, financial condition, results of operations and cash flows.
If commodity prices decrease to a level such that our future undiscounted cash flows from our properties are less than their carrying value for a significant period of time, we perform a reviewwill be required to take write-downs of the subject properties, but such a review will not reveal all existing or potential problems. In the coursecarrying values of our due diligence,properties.
Accounting rules require that we may notperiodically review every well, pipeline or associated facility. We cannot necessarily observe structuralthe carrying value of our properties for possible impairment. Based on specific market factors and environmental problems,circumstances at the time of prospective impairment reviews, and the continuing evaluation of development plans, production data, economics and other factors such as pipe corrosion or groundwater contamination, when a review is performed. We may be unable to obtain contractual indemnities from the seller for liabilities created prior to our purchase of the property. Welease expirations, changes in drilling plans and adverse drilling results, we may be required to assumewrite down the riskcarrying value of our properties. A write down constitutes a non-cash charge to earnings. For the physical conditionyear ended December 31, 2020, we recorded non-cash impairment charges of theapproximately $194.3 million and $3.6 million on oil and gas properties in addition to the risk that the properties may not perform in accordance with our expectations.
Our exploration and development projects require substantial capital expenditures. We may be unable to obtain required capital or financing on satisfactory terms, which could lead to a declineprimarily in our reserves.
The oilCore DJ Basin field and natural gas industry is capital intensive. We makeour northern field, respectively, and expect to continue to make substantial capital expenditures for the exploitation, development and acquisition of oil and natural gas reserves. We expect to fund our 2018 capital expenditures with borrowings under our revolving credit facility and possibly through asset salesif market or additional capital markets transactions. The actual amount and timing of our future capital expenditures may differ materially from our estimates as a result of, among other things,economic conditions deteriorate or if oil, natural gas and NGL prices actual drilling results, the availability of drilling rigs and other services and equipment, and regulatory, technological and competitive developments. A reduction in commodity prices from current levels may result in a decrease in our actual capital expenditures, which would negatively impact our ability to grow production. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.”

See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.”
Substantially all of our producing properties are located in the DJ Basin of Colorado, making us vulnerable to risks associated with operating in one major geographic area. Specifically, as the DJ Basin is an area of high industry activity,decline, we may be unable to hire, trainincur impairment charges in 2021 or retain qualified personnel needed to manage and operate our assets.
Substantially all of our producing properties are geographically concentrated in the DJ Basin of Colorado, an area inlater periods, which industry activity has increased rapidly. At December 31, 2017, substantially all of our total estimated proved reserves were attributable to properties located in this area. As a result of this concentration, we may be disproportionately exposed to the impact of regional supply and demand factors or other regional events, delays or interruptions of production from wells in this area caused by governmental regulation, including at the state and local level, processing or transportation capacity constraints, market limitations, water shortages or other drought or extreme weather related conditions or interruption of the processing or transportation of oil, natural gas or NGL. For example, bottlenecks in processing and transportation that have occurred in some recent periods in the Wattenberg Field have negatively affected our results of operations. Similarly, the concentration of our producing assets within a small number of producing formations exposes us to risks, such as changes in field-wide rules that could adversely affect development activities or production relating to those formations. In addition, in areas where exploration and production activities are increasing, as has been the case in recent years in the Wattenberg Field, the demand for, and cost of, drilling rigs, equipment, supplies, personnel, and oilfield services increase. Shortages or the high cost of drilling rigs, equipment, supplies, personnel, or oilfield services could delay or adversely affect our development and exploration operations or cause us to incur significant expenditures that are not provided for in our capital forecast, which could have a material adverse effect on our business, financial condition, or results of operations.
Specifically, demand for qualified personnel in this area, and the cost to attract and retain such personnel, has increased over the past few years and may increase substantially in the future. Moreover, our competitors, including those operating in multiple basins, may be able to offer better compensation packages to attract and retain qualified personnel than we are able to offer. Any delay or inability to secure the personnel necessary for us to continue or complete our current and planned development activities could have a negative effect on production volumes or significantly increase costs, which could have a material adverse effect on our results of operations, liquidityoperations.
Risks Relating to our Reserves and financial condition.Reserve Estimation
ChangesReserve estimates depend on many assumptions that may turn out to be inaccurate. Any material inaccuracies in reserve estimates or underlying assumptions will materially affect the legalquantities and regulatory environment governing thepresent value of our reserves.
The process of estimating oil and natural gas industry, particularly changes specificreserves is complex. It requires interpretations of available technical data and many assumptions, including assumptions relating to current and future economic conditions and commodity prices. Any significant inaccuracies in these interpretations or assumptions could materially affect the estimated quantities and present value of our reserves.
In order to prepare reserve estimates, we must project production rates and timing of development expenditures. We must also analyze available geological, geophysical, production and engineering data. The extent, quality and reliability of this data can vary. The process also requires economic assumptions about matters such as oil, natural gas and NGL prices, drilling and operating expenses, capital expenditures, taxes and availability of funds.
Actual future production, oil, natural gas and NGL prices, revenues, taxes, development expenditures, operating expenses and quantities of recoverable oil and natural gas reserves will vary from our estimates. Any significant variance could materially affect the estimated quantities and present value of our reserves. In addition, we may revise reserve estimates to reflect production history, results of exploration and development, existing commodity prices and other factors, many of which are beyond our control.
29

You should not assume that the present value of future net revenues from our reserves is the current market value of our estimated reserves. We generally base the estimated discounted future net cash flows from reserves on prices and costs on the date of the estimate. Actual future prices and costs may differ materially from those used in the present value estimate. For example, our estimated proved reserves as of December 31, 2020 were calculated under SEC rules using the unweighted arithmetic average first-day-of-the-month prices for the prior 12 months of $39.57/Bbl for oil and $1.99/MMBtu for natural gas, which for certain periods of 2020 were substantially above the available spot oil and natural gas prices. Using lower prices in estimating proved reserves would likely result in a reduction in proved reserve volumes due to economic limits.
There is a limited amount of production data from horizontal wells completed in the DJ Basin. As a result, reserve estimates associated with horizontal wells in this area are subject to greater uncertainty than estimates associated with reserves attributable to vertical wells in the same area.
Reserve engineers rely in part on the production history of nearby wells in establishing reserve estimates for a particular well or field. Horizontal drilling in the DJ Basin is a relatively recent development, whereas vertical drilling has been utilized by producers in this area for over 50 years. As a result, the amount of Colorado,production data from horizontal wells available to reserve engineers is relatively small compared to that of production data from vertical wells. Until a greater number of horizontal wells have been completed in the DJ Basin, and a longer production history from these wells has been established, there may be a greater variance in our proved reserves on a year-over-year basis due to the transition from vertical to horizontal reserves in both the proved developed and proved undeveloped categories. We cannot assure you that any such variance would not be material and any such variance could have a material and adverse effectimpact on our business

Our business is subject to various formscash flows and results of government regulation. Some local governments are adopting new requirements and restrictions on hydraulic fracturing and other oil and natural gas operations. Some local governments in Colorado, for instance, have amended their land use regulations to impose new requirements on oil and gas development, while other local governments have entered memoranda of agreement with oil and gas producers to accomplish the same objective. Beyond that, during the past few years, a total of five Colorado cities have passed voter initiatives temporarily or permanently prohibiting hydraulic fracturing. Since that time, local district courts have struck down the ordinances for certain of those Colorado cities, and such decisions were upheld by the Colorado Supreme Court in May 2016. Nevertheless, there is a continued risk that cities will adopt local ordinances that seek to regulate the time, place, and manner of hydraulic fracturing activities and oil and natural gas operations within their respective jurisdictions.

In addition, in 2014 and 2016, opponents of hydraulic fracturing sought statewide ballot initiatives that would have restricted oil and gas development in Colorado. The 2014 initiatives were withdrawn in returnIf our horizontal wells do not allow for the creation of a task force to craft recommendations for minimizing land use conflicts over the locationextraction of oil and natural gas facilities,in a manner or to the extent that we anticipate, we may not realize an acceptable return on our investments in such projects.
Unless we replace our reserves with new reserves and nonedevelop those reserves, our reserves and production will decline, which would adversely affect our future cash flows and results of the 2016 initiatives were successful. We cannot predict the natureoperations.
Producing oil and natural gas reservoirs generally are characterized by declining production rates that vary depending upon reservoir characteristics and other factors. Unless we conduct successful ongoing exploitation, development and exploration activities or outcome ofcontinually acquire properties containing proved reserves, our proved reserves will decline as those reserves are produced. Our future ballot initiatives, which could materially impactreserves and production, and therefore our future cash flow and results of operations, production,are highly dependent on our success in efficiently developing and exploiting our current reserves and economically finding or acquiring additional recoverable reserves. We may not be able to develop, exploit, find or acquire sufficient additional reserves to replace our current and future production. If we are requiredunable to cease operating in anyreplace our current and future production, the value of the areas in which we now

operate as the result of bans or moratoria on drilling or related oilfield services activities, it could have a material effect onour reserves will decrease, and our business, financial condition and results of operations.operations would be adversely affected.

A substantial portion of our reserves are located in urban areas, which could increase our costs of development and delay production.
Additionally, weA substantial portion of our reserves are subject to laws and regulations concerning the location, spacing and permittinglocated in urban portions of the oilDJ Basin, which could disproportionately expose us to operational and natural gas wellsregulatory risk in that area. Much of our operations are within the city limits of various municipalities in northeastern Colorado. In such urban and other populated areas, we drill, among other matters. In particular,may incur additional expenses, including expenses relating to mitigation of noise, odor and light that may be emitted in our business utilizes a methodology available in Colorado known as “forced pooling,” which refersoperations, expenses related to the abilityappearance of a holderour facilities and limitations regarding when and how we can operate. The process of an oil and natural gas interest in a particular prospectiveobtaining permits for drilling spacing unitor for gathering lines to applymove our production to the Colorado Oil & Gas Conservation Commission ("COGCC") for an order forcing all other holders of oil and natural gas interestsmarket in such area into a common pool for purposes of developing that drilling spacing unit. This methodology is especially important for our operationsareas may be more time consuming and costly than in the Greeley area, where there are many interest holders. Changes in the legalmore rural areas and regulatory environment governing our industry, particularly any changes to Colorado forced pooling procedures that make forced pooling more difficult to accomplish, could result in increased compliance costs and adversely affect our business, financial condition and results of operations.

Our cash flow from operations and access to capital are subject to a number of variables, including:
our proved reserves;
the level of hydrocarbons we are able to produce from existing wells;
the prices at which our production is sold;
the availability of takeaway capacity;
our ability to acquire, locate and produce new reserves; and
our ability to borrow under our revolving credit facility.
If our revenues or the borrowing base under our revolving credit facility decreases as a result of lower oil, natural gas and NGL prices, operating difficulties, declines in reserves or for any other reason, we may have limited ability to obtain the capital necessary to sustain our operations and growth at current levels. If additional capital is needed, wesuch permits may not be able to obtain debt or equity financing on terms acceptable to us, ifbe obtained at all. If cash flow generated byIn addition, we may experience a higher rate of litigation or increased insurance and other costs related to our operations or available borrowings underfacilities in such highly populated areas.

SEC rules could limit our revolving credit facility areability to book additional PUDs in the future.
SEC rules require that, subject to limited exceptions, PUDs may only be booked if they relate to wells scheduled to be drilled within five years after the date of booking. This requirement has limited and may continue to limit our ability to book additional PUDs as we pursue our drilling program. Moreover, we may be required to write down our PUDs if we do not sufficientdrill or plan on delaying those wells within the required five-year timeframe. For example, for the year ended December 31, 2020, we wrote down approximately 23,926 MBoe of PUDs.

Risks Relating to meet our capital requirements, the failure to obtain additional financing could result in a curtailment of our operations relating to development of our properties, which in turn could lead to a decline in our reserves and production, and would adversely affect our business, financial condition and results of operations.

Operations
Drilling for and producing oil and natural gas are high risk activities with many uncertainties that could adversely affect our business, financial condition or results of operations.
Our future financial condition and results of operations will depend on the success of our exploitation, development and acquisition activities, which are subject to numerous risks beyond our control, including the risk that drilling will not result in commercially viable oil and natural gas production.
Our decisions to purchase, explore, develop or otherwise exploit prospects or properties will depend in part on the evaluation of data obtained through geophysical and geological analyses, production data and engineering studies, the results of which are often inconclusive or subject to varying interpretations. For a discussion of the uncertainty involved in these processes, see “—Reserve estimates depend on many assumptions that may turn out to be inaccurate. Any material inaccuracies in reserve estimates or underlying assumptions will materially affect the quantities and present value of our reserves.” In addition, our cost of drilling, completing and operating wells is often uncertain before drilling commences.
Further, many factors may curtail, delay or cancel our scheduled drilling projects, including the following:
delays imposed by or resulting from compliance with environmental and other regulatory requirements including limitations on or resulting from wastewater discharge and disposal, subsurface injections, GHG emissions and hydraulic fracturing;
pressure or irregularities in geological formations;
shortages of or delays in obtaining equipment and qualified personnel or in obtaining water for hydraulic fracturing activities;
lack of available capacity on interconnecting transmission pipelines;
equipment failures or accidents, such as fires or blowouts;

lack of available gathering facilities or delays in construction of gathering facilities;
adverse weather conditions, such as blizzards, tornados and ice storms;
issues related to compliance with environmental and other governmental regulations;
environmental hazards, such as natural gas leaks, oil spills, pipeline and tank ruptures, encountering naturally occurring radioactive materials, and unauthorized discharges of brine, well stimulation and completion fluids, toxic gases or other pollutants into the surface and subsurface environment;
declines in oil, natural gas and NGL prices;
limited availability of financing at acceptable terms;
title problems or legal disputes regarding leasehold rights; and
limitations in the market for oil, natural gas and NGL.
Our identified drilling locations are scheduled over many years, making them susceptible to uncertainties that could materially alter the occurrence or timing of their drilling. In addition, we may not be able to raise the substantial amount of capital that would be necessary to drill such locations.
Our management team has specifically identified and scheduled certain drilling locations as an estimation of our future multi-year drilling activities on our existing acreage. These locations represent a significant part of our growth strategy. Our ability to drill and develop these locations depends on a number of uncertainties, including oil, natural gas and NGL prices, the availability and cost of capital, drilling and production costs, availability of drilling services and equipment, drilling results, lease expirations, gathering system and pipeline transportation constraints, access to and availability of water sourcing and distribution systems, regulatory approvals and other factors. Because of these uncertain factors, we do not know if the numerous potential well locations we have identified will ever be drilled or if we will be able to produce natural gas or oil from these or any other potential locations. In addition, unless production is established within the spacing units covering the undeveloped acres on which some of the potential locations are obtained or if existing producing wells that are holding leases with other potential locations cease to continue to produce in commercial quantities, the leases for such acreage will expire. As such, our actual drilling activities may materially differ from those presently identified.
In addition, we will require significant additional capital over a prolonged period in order to pursue the development of these locations, and we may not be able to raise or generate the capital required to do so. Any drilling activities we are able to conduct on these potential locations may not be successful or result in our ability to add additional proved reserves to our overall proved reserves or may result in a downward revision of our estimated proved reserves, which could have a material adverse effect on our future business and results of operations.
A substantial portion
31

Table of our reserves are located in urban areas, which could increase our costs of development and delay production.Contents
A substantial portion of our reserves are located in urban portions of the DJ Basin, which could disproportionately expose us to operational and regulatory risk in that area. Much of our operations are within the city limits of various municipalities in northeastern Colorado. In such urban and other populated areas, we may incur additional expenses, including expenses relating to mitigation of noise, odor and light that may be emitted in our operations, expenses related to the appearance of our facilities and limitations regarding when and how we can operate. The process of obtaining permits for drilling or for gathering lines to move our production to market in such areas may be more time consuming and costly than in more rural areas. In addition, we may experience a higher rate of litigation or increased insurance and other costs related to our operations or facilities in such highly populated areas.
Our drilling and production programs may not be able to obtain access on commercially reasonable terms or otherwise to truck transportation, pipelines, gas gathering, transmission, storage and processing facilities to market our oil and gas production, and our initiatives to expand our access to midstream and operational infrastructure may be unsuccessful.
The marketing of oil and natural gas production depends in large part on the capacity and availability of trucks, pipelines and storage facilities, gas gathering systems and other transportation, processing and refining facilities. Access to such facilities is, in many respects, beyond our control. The availability of these facilities also could be impacted by the comprehensive regulatory structure under which these facilities operate, as detailed in “Business and Properties — Regulation Affecting Sales and Transportation of Commodities.” If there is insufficient capacity available on these systems, or if these facilities are unavailable to us on commercially reasonable terms or otherwise, we could be forced to shut in some production or delay or discontinue drilling plans and commercial production following a discovery of hydrocarbons. We rely (and expect to rely in the future) on facilities developed and owned by third parties in order to store, process, transmit and sell our oil and gas production. Our plans to develop and sell our oil and gas reserves could be materially and adversely affected by the

inability or unwillingness of third parties to provide sufficient facilities and services to us on commercially reasonable terms or otherwise, especially in areas of planned expansion where such facilities do not currently exist. The amount of oil and gas that can be produced is subject to limitation in certain circumstances, such as pipeline interruptions due to scheduled and unscheduled maintenance, excessive pressure, damage to the gathering, transportation, refining or processing facilities, or lack of capacity on such facilities. For example, recent increases in activity in the DJ Basin have contributed to bottlenecks in processing and transportation that have negatively affected our results of operations, and these adverse effects may be disproportionately severe to us compared to our more geographically diverse competitors. Additionally, in recent months, we have experiencedexperience constraints from time to time on the capacity available in certain pipelines that we use to transport natural gas and have been forced to shut in some production from time to time. Capacity constraints typically reduce the productivity of some of our older vertical wells and may on occasion limit incremental production from some of our newer horizontal wells. This constrains our production and reduces our revenue from the affected wells. Capacity constraints affecting natural gas production also impact the associated NGL. We are also dependent on the availability and capacity of oil purchasers for our production. Increases in the amount of oil that we transport out of the DJ Basin for sale would result in an increase in our transportation costs and would reduce the price we receive for the affected production.
Similarly, the concentration of our assets within a small number of producing formations exposes us to risks, such as changes in field-wide rules, which could adversely affect development activities or production relating to those formations. In addition, in areas where exploration and production activities are increasing, as has been the case in recent years in the DJ Basin, we are subject to increasing competition for drilling rigs, oilfield equipment, services, supplies and qualified personnel, which may lead to periodic shortages or delays. The curtailments arising from these and similar circumstances may last from a few days to several months, and in many cases, we may be provided only limited, if any, notice as to when these circumstances will arise and their duration.
While we have undertaken initiatives to expand our access to midstream and operational infrastructure, these initiatives may be delayed or unsuccessful. As a result, our business, financial condition and results of operations could be adversely affected.
Restrictions in our existing and future debt agreements could limit our growth and our ability to engage in certain activities.
Our debt arrangements contain a number of significant covenants, including restrictive covenants that may limit our ability to, among other things:
incur additional indebtedness;
sell assets;
make loans to others;
make certain acquisitions and investments;
enter into mergers, consolidations or other transactions resulting in the transfer of all or substantially all of our assets;
make certain payments, including paying dividends or distributions in respect of our equity;
hedge future production or interest rates;
redeem and prepay other debt;
incur liens; and
engage in certain other transactions without the prior consent of the lenders.
In addition, our debt arrangements require us to maintain certain financial ratios or to reduce our indebtedness if we are unable to comply with such ratios. These restrictions may also limit our ability to obtain future financings to withstand a future downturn in our business or the economy in general, or to otherwise conduct necessary corporate activities. We may also be prevented from taking advantage of business opportunities that arise because of the limitations that the restrictive covenants under our debt arrangements will impose on us.
Our revolving credit facility limits the amount we can borrow up to the lower of our aggregate lender commitments and a borrowing base amount, which the lenders, in their sole discretion, will determine on a semi-annual basis based upon projected revenues from the oil and natural gas properties securing our loan. The lenders will be able to unilaterally adjust the borrowing base and the borrowings permitted to be outstanding under our revolving credit facility. Any increase in the borrowing base requires the consent of the lenders holding 100% of the commitments. If the requisite number of lenders does

not agree to a proposed borrowing base, then the borrowing base will be the highest borrowing base acceptable to such lenders. We will be required to repay outstanding borrowings in excess of the borrowing base. Our borrowing base is $700.0 million, subject to the current maximum lending commitments of $650.0 million.
A breach of any covenant in our revolving credit facility will result in a default under the revolving credit facility after any applicable grace periods. A default, if not waived, could result in acceleration of the indebtedness outstanding under the facility and a default with respect to, and an acceleration of, the indebtedness outstanding under other debt agreements. The accelerated indebtedness would become immediately due and payable. If that occurs, we may not be able to make all of the required payments or borrow sufficient funds to refinance such indebtedness. Even if new financing were available at that time, it may not be on terms that are acceptable to us. In addition, our obligations under our revolving credit facility are secured by perfected first priority liens and security interests on substantially all of our assets, including mortgage liens on oil and natural gas properties having at least 90% of the reserve value as determined by reserve reports, and if we are unable to repay our indebtedness under the revolving credit facility, the lenders could seek to foreclose on our assets.
We may not be able to generate sufficient cash to service all of our indebtedness and may be forced to take other actions to satisfy our obligations under our debt arrangements, which may not be successful.
Our ability to make scheduled payments on or to refinance our indebtedness obligations, including our revolving credit facility and our Senior Notes, depends on our financial condition and operating performance, which are subject to prevailing economic and competitive conditions and certain financial, business and other factors beyond our control. If oil and natural gas prices remain at their current level for an extended period of time or decline, we may not be able to maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness.
If our cash flows and capital resources are insufficient to fund debt service obligations, we may be forced to reduce or delay investments and capital expenditures, sell assets, seek additional capital or restructure or refinance indebtedness. Our ability to restructure or refinance indebtedness will depend on the condition of the capital markets and our financial condition at such time. Any refinancing of indebtedness could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict business operations. The terms of existing or future debt arrangements may restrict us from adopting some of these alternatives. In addition, any failure to make payments of interest and principal on outstanding indebtedness on a timely basis could harm our ability to incur additional indebtedness. In the absence of sufficient cash flows and capital resources, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet debt service and other obligations. Our revolving credit facility and the indentures governing our 2024 Notes and 2026 Notes currently restrict our ability to dispose of assets and our use of the proceeds from such disposition. We may not be able to consummate those dispositions, and the proceeds of any such disposition may not be adequate to meet any debt service obligations then due. These alternative measures may not be successful and may not permit us to meet scheduled debt service obligations.
In addition, we will require significant additional capital over a prolonged period in order to pursue the development of these locations, and we may not be able to raise or generate the capital required to do so. Any drilling activities we are able to conduct on these potential locations may not be successful or result in our ability to add additional proved reserves to our overall proved reserves or may result in a downward revision of our estimated proved reserves, which could have a material adverse effect on our future business and results of operations.
Our derivative activities could result in financial losses or could reduce our earnings.
To achieve more predictable cash flows and reduce our exposure to adverse fluctuations in the prices of oil, natural gas and NGL, we enter into commodity derivative contracts for a significant portion of our production, primarily consisting of swaps, put options and call options. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Overview—Sources of Our Revenues.” Accordingly, our earnings may fluctuate significantly as a result of changes in fair value of our derivative instruments.
Derivative instruments also expose us to the risk of financial loss in some circumstances, including when:
production is less than the volume covered by the derivative instruments;
the counterparty to the derivative instrument defaults on its contractual obligations;
there is an increase in the differential between the underlying price in the derivative instrument and actual prices received; or
there are issues with regard to legal enforceability of such instruments.

The use of derivatives may, in some cases, require the posting of cash collateral with counterparties. If we enter into derivative instruments that require cash collateral and commodity prices or interest rates change in a manner adverse to us, our cash otherwise available for use in our operations would be reduced, which could limit our ability to make future capital expenditures and make payments on our indebtedness, and which could also limit the size of our borrowing base. Future collateral requirements will depend on arrangements with our counterparties, highly volatile oil, natural gas and NGL prices and interest rates. In addition, derivative arrangements could limit the benefit we would receive from increases in the prices for oil, natural gas and NGL, which could also have an adverse effect on our financial condition.
Our commodity derivative contracts expose us to risk of financial loss if a counterparty fails to perform under a contract. Disruptions in the financial markets could lead to sudden decreases in a counterparty’s liquidity, which could make them unable to perform under the terms of the contract and we may not be able to realize the benefit of the contract. We are unable to predict sudden changes in a counterparty’s creditworthiness or ability to perform. Even if we do accurately predict sudden changes, our ability to negate the risk may be limited depending upon market conditions.
During periods of declining commodity prices, our derivative contract receivable positions generally increase, which increases our counterparty credit exposure. While we utilize multiple counterparties, if the creditworthiness of our counterparties deteriorates and results in their nonperformance, we could incur a significant loss with respect to our commodity derivative contracts.
Reserve estimates depend on many assumptions that may turn out to be inaccurate. Any material inaccuracies in reserve estimates or underlying assumptions will materially affect the quantities and present value of our reserves.
The process of estimating oil and natural gas reserves is complex. It requires interpretations of available technical data and many assumptions, including assumptions relating to current and future economic conditions and commodity prices. Any significant inaccuracies in these interpretations or assumptions could materially affect the estimated quantities and present value of our reserves.
In order to prepare reserve estimates, we must project production rates and timing of development expenditures. We must also analyze available geological, geophysical, production and engineering data. The extent, quality and reliability of this data can vary. The process also requires economic assumptions about matters such as oil, natural gas and NGL prices, drilling and operating expenses, capital expenditures, taxes and availability of funds.
Actual future production, oil, natural gas and NGL prices, revenues, taxes, development expenditures, operating expenses and quantities of recoverable oil and natural gas reserves will vary from our estimates. Any significant variance could materially affect the estimated quantities and present value of our reserves. In addition, we may revise reserve estimates to reflect production history, results of exploration and development, existing commodity prices and other factors, many of which are beyond our control.
You should not assume that the present value of future net revenues from our reserves is the current market value of our estimated reserves. We generally base the estimated discounted future net cash flows from reserves on prices and costs on the date of the estimate. Actual future prices and costs may differ materially from those used in the present value estimate. For example, our estimated proved reserves as of December 31, 2017 were calculated under SEC rules using the unweighted arithmetic average first-day-of-the-month prices for the prior 12 months of $51.34/Bbl for oil and $2.98/MMBtu for natural gas, which for certain periods of 2017 were substantially above the available spot oil and natural gas prices. Using lower prices in estimating proved reserves would likely result in a reduction in proved reserve volumes due to economic limits.
There is a limited amount of production data from horizontal wells completed in the DJ Basin. As a result, reserve estimates associated with horizontal wells in this area are subject to greater uncertainty than estimates associated with reserves attributable to vertical wells in the same area.
Reserve engineers rely in part on the production history of nearby wells in establishing reserve estimates for a particular well or field. Horizontal drilling in the DJ Basin is a relatively recent development, whereas vertical drilling has been utilized by producers in this area for over 50 years. As a result, the amount of production data from horizontal wells available to reserve engineers is relatively small compared to that of production data from vertical wells. Until a greater number of horizontal wells have been completed in the DJ Basin, and a longer production history from these wells has been established, there may be a greater variance in our proved reserves on a year-over-year basis due to the transition from vertical to horizontal reserves in both the proved developed and proved undeveloped categories. We cannot assure you that any such variance would not be material and any such variance could have a material and adverse impact on our cash flows and results of operations. If our horizontal wells do not allow for the extraction of oil and natural gas in a manner or to the extent that we anticipate, we may not realize an acceptable return on our investments in such projects.

Part of our strategy involves drilling using the latest available horizontal drilling and completion techniques, which involve risks and uncertainties in their application.
Our operations involve utilizing the latest drilling and completion techniques as developed by us and our service providers. During the year ended December 31, 2017,2020, we have drilled 32337 gross one-mile equivalentoperated horizontal wells and have completed 33245 gross one-mile equivalentoperated horizontal wells and therefore are subject to increased risks associated with horizontal drilling as compared to companies that have greater experience in horizontal drilling activities. Risks that we face while drilling include, but are not limited to, failing to land our wellbore in the desired drilling zone, not staying in the desired drilling zone while drilling horizontally through the formation, not running our casing the entire length of the wellbore and not being able to run tools and other equipment consistently through the horizontal wellbore. Risks that we face while completing our wells include, but are not limited to, not being able to fracture stimulate the planned number of stages, not being able to run tools the entire length of the wellbore during completion operations and not successfully cleaning out the wellbore after completion of the final fracture stimulation stage. In addition, our horizontal drilling activities may adversely affect our ability to successfully drill in one or more of our identified vertical drilling locations. Ultimately, the success of these drilling and completion techniques can only be evaluated over time as more wells are drilled and production profiles are established over a sufficiently long time period. If our drilling results are less than anticipated or we are unable to execute our drilling program because of capital constraints, lease expirations, access to gathering systems and/or commodity prices decline, the return on our investment in these areas may not be as attractive as we anticipate. Further, as a result of any of these developments we could incur material write-downs of our oil and natural gas properties and the value of our undeveloped acreage could decline in the future.
Approximately 60%

Our development and exploratory drilling efforts and our net leasehold acreage is undeveloped, and that acreagewell operations may not ultimately be developedprofitable or become commercially productive, which could cause us to lose rights underachieve our leases as well as have a material adverse effect on our oil and natural gas reserves and future production and, therefore, our future cash flow and income.
As of December 31, 2017, approximately 60% of our net leasehold acreage was undeveloped, or acreage on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of oil and natural gas regardless of whether such acreage contains proved reserves. Unless production is established on the undeveloped acreage covered by our leases, such leases will expire. Our future oil and natural gas reserves and production and, therefore, our future cash flow and income are highly dependent on successfully developing our undeveloped leasehold acreage.targeted returns.
We are requiredhave acquired significant amounts of unproved property in order to pay feesfurther our development efforts and expect to our service providers based on minimum volumes under long-term contracts regardless of actual volume throughput.
We may enter into firm transportation, gas processing, gathering and compression service, water handling and treatment, or other agreements that require minimum volume delivery commitments. Our oil marketer is currently partycontinue to a firm transportation agreement that commenced in November 2016 and has a ten-year term, which obligates them to meet delivery commitments of 45,000 Bbl/dundertake acquisitions in the first year, 55,800 Bbl/d in the second year, 61,800 Bbl/d in 2019 through 2023,future. Development and 58,000 Bbl/d in years 2024 through 2026. We amended our agreement with our oil marketer that requires us to sell all of our crude oil from an area of mutual interest in exchange for a make-whole provision that allows us to satisfy any minimum volume commitment deficiencies incurred by our oil marketer with future barrels of crude oil in excess of their minimum volume commitment through October 31, 2018. In December 2017, we extended the term of this agreement through October 31, 2019 and posted a letter of credit in the amount of $35.0 million. We evaluate our contracts for loss contingencies and accrue for such losses, if the loss can be reasonably estimated and deemed probable. We also have one long-term crude oil gathering commitment. The gathering commitment has a term of ten years with a minimum volume commitment of an average 9,167 Bbl/d in year one, 17,967 Bbl/d in year two, 18,800 Bbl/d for years three through five and 10,000 Bbl/d for years six through ten. The aggregate amount of estimated payments over the ten-year term of these agreements is approximately $927.3 million. If we have insufficient production to meet the minimum volumes under this agreement or any other firm commitment agreement we may enter into, our cash flow from operations will be reduced, which may require us to reduce or delay our planned investments and capital expenditures or seek alternative means of financing, all of which may have a material adverse effect on our results or operations.
The prices we receive for our production may be affected by local and regional factors.
The prices we receive for our production will be determined to a significant extent by factors affecting the local and regional supply of and demand for oil and natural gas, including the adequacy of the pipeline and processing infrastructure in the region to process, and transport, our production and that of other producers. Those factors result in basis differentials between the published indices generally used to establish the price received for regional oil and natural gas production and the actual price we receive for our production, which may be lower than index prices. If the price differentials pursuant to which our production is subject were to widen due to oversupply or other factors, our revenue could be negatively impacted.

Extreme weather conditions could adversely affect our ability to conduct drilling activities in the areas where we operate.
Our exploration, exploitation and development activities and equipment could be adversely affected by extreme weather conditions, such as winter storms, which may cause a loss of production from temporary cessation of activity or lost or damaged facilities and equipment. Such extreme weather conditions could also impact other areas of our operations, including access to ourexploratory drilling and production facilities for routine operations, maintenanceactivities are subject to many risks, including the risk that no commercially productive reservoirs will be discovered. We acquire unproved properties and repairslease undeveloped acreage that we believe will enhance our growth potential and the availability of, and our access to, necessary third-party services, such as gathering, processing, compression and transportation services. These constraints and the resulting shortages or high costs could delay or temporarily halt our operations and materially increase our operation and capital costs, which could have a material adverse effect on our business, financial condition and results of operations.
SEC rules could limitoperations over time. However, we cannot assure you that all prospects will be economically viable or that we will not abandon our ability to book additional PUDsinvestments. Additionally, we cannot assure you that unproved property acquired by us or undeveloped acreage leased by us will be profitably developed, that wells drilled by us in the future.
SEC rules requireprospects that subject to limited exceptions, PUDs may only be booked if they relate to wells scheduled to be drilled within five years after the date of booking. This requirement has limited and may continue to limit our ability to book additional PUDs as we pursue will be productive or that we will recover all or any portion of our drilling program. Moreover, we may be required to write down our PUDs if we do not drillinvestment in such unproved property or plan on delaying those wells within the required five-year timeframe.wells.
The development of our estimated proved undeveloped reserves may take longer and may require higher levels of capital expenditures than we currently anticipate. Therefore, our estimated proved undeveloped reserves may not be ultimately developed or produced.
At December 31, 2017,2020, approximately 65%23% of our total estimated proved reserves were classified as proved undeveloped. The development of our estimated proved undeveloped reserves of 190,69333,583 MBoe will require an estimated $1.6 billion$178.0 million of development capital over the next fivetwo years.
Development of these reserves may take longer and require higher levels of capital expenditures than we currently anticipate. The future development of our proved undeveloped reserves is dependent on future commodity prices, costs and economic assumptions that align with our internal forecast, as well as access to liquidity sources, such as the capital markets, our revolving credit facilityRBL Credit Facility and derivative contracts. Delays in the development of our reserves, increases in costs to drill and develop such reserves, or decreases in commodity prices will reduce the PV-10 value of our estimated proved undeveloped reserves and future net revenues estimated for such reserves and may result in some projects becoming uneconomic. In addition, delays in the development of reserves could cause us to have to reclassify our proved undeveloped reserves as unproved reserves.
We participate in oil and gas leases with third parties who may not be able to fulfill their commitments to our projects.
We own less than 100% of the working interest in the oil and gas leases on which we conduct operations, and other parties will own the remaining portion of the working interest. Financial risks are inherent in any operation where the cost of drilling, equipping, completing and operating wells is shared by more than one person. We could be held liable for joint activity obligations of other working interest owners, such as nonpayment of costs and liabilities arising from the actions of other working interest owners. In addition, declines in oil, natural gas and NGL prices may increase the likelihood that some of these working interest owners, particularly those that are smaller and less established, are not able to fulfill their joint activity obligations. A partner may be unable or unwilling to pay its share of project costs, and, in some cases, a partner may declare bankruptcy. In the event any of our project partners do not pay their share of such costs, we would likely have to pay those costs, and we may be unsuccessful in any efforts to recover these costs from our partners, which could materially adversely affect our financial position.
We own non-operating interests in properties developed and operated by third parties, and as a result, we are unable to control the operation and profitability of such properties.
We participate in the drilling and completion of wells with third-party operators that exercise exclusive control over such operations. As a participant, we rely on the third-party operators to successfully operate these properties pursuant to joint operating agreements and other similar contractual arrangements.
As a participant in these operations, we may not be able to maximize the value associated with these properties in the manner we believe appropriate, or at all. For example, we cannot control the success of drilling and development activities on properties operated by third parties, which depend on a number of factors under the control of a third-party operator, including such operator’s determinations with respect to, among other things, the nature and timing of drilling and operational activities, the timing and amount of capital expenditures and the selection of suitable technology. In addition, the third-party operator’s

operational expertise and financial resources and its ability to gain the approval of other participants in drilling wells will impact the timing and potential success of drilling and development activities in a manner that we are unable to control. A third-party operator’s failure to adequately perform operations, breach of the applicable agreements or failure to act in ways that are favorable to us could reduce our production and revenues, negatively impact our liquidity and cause us to spend capital in excess of our current plans, and have a material adverse effect on our financial condition and results of operations.
If commodity prices decrease to a level such that our future undiscounted cash flows from our properties are less than their carrying value for a significant period of time, we will be required to take write-downs of the carrying values of our properties.
Accounting rules require that we periodically review the carrying value of our properties for possible impairment. Based on specific market factors and circumstances at the time of prospective impairment reviews, and the continuing evaluation of development plans, production data, economics and other factors such as lease expirations, changes in drilling plans and adverse drilling results, we may be required to write down the carrying value of our properties. A write down constitutes a non-cash charge to earnings. If market or other economic conditions deteriorate or if oil, natural gas and NGL prices continue to decline, we may incur impairment charges in 2018 or later periods, which may have a material adverse effect on our results of operations.
Unless we replace our reserves with new reserves and develop those reserves, our reserves and production will decline, which would adversely affect our future cash flows and results of operations.
Producing oil and natural gas reservoirs generally are characterized by declining production rates that vary depending upon reservoir characteristics and other factors. Unless we conduct successful ongoing exploitation, development and exploration activities or continually acquire properties containing proved reserves, our proved reserves will decline as those reserves are produced. Our future reserves and production, and therefore our future cash flow and results of operations, are highly dependent on our success in efficiently developing and exploiting our current reserves and economically finding or acquiring additional recoverable reserves. We may not be able to develop, exploit, find or acquire sufficient additional reserves to replace our current and future production. If we are unable to replace our current and future production, the value of our reserves will decrease, and our business, financial condition and results of operations would be adversely affected.
Conservation measures and technological advances could reduce demand for oil, natural gas and NGL.
Fuel conservation measures, alternative fuel requirements, increasing consumer demand for alternatives to oil, natural gas and NGL, technological advances in fuel economy and energy generation devices could reduce demand for oil, natural gas and NGL. The impact of the changing demand for oil and gas services and products may have a material adverse effect on our business, financial condition, results of operations and cash flows.
We depend upon several significant purchasers for the sale of most of our oil and natural gas production. The loss of one or more of these purchasers could, among other factors, limit our access to suitable markets for the oil, natural gas and NGL we produce.
The availability of a ready market for any oil, natural gas and NGL we produce depends on numerous factors beyond the control of our management, including but not limited to the extent of domestic production and imports of oil, the proximity and capacity of pipelines, the availability of skilled labor, materials and equipment, the effect of state and federal regulation of oil and natural gas production and federal regulation of oil and gas sold in interstate commerce. In addition, we depend upon several significant purchasers for the sale of most of our oil and natural gas production. See “Business—Operations—Marketing and Customers.” We cannot assure you that we will continue to have ready access to suitable markets for our future oil and natural gas production.
The inability of one or more of our purchasers to meet their obligations may adversely affect our financial results.
We have exposure to credit risk through receivables from purchasers of our oil, natural gas and NGL production. Three, four and four purchasers accounted for more than 10% of our revenues in the years ended December 31, 2017, 2016 and 2015 respectively. This concentration of purchasers may impact our overall credit risk in that these entities may be similarly affected by changes in economic conditions or commodity price fluctuations. We do not require our customers to post collateral. The inability or failure of our significant purchasers to meet their obligations to us or their insolvency or liquidation may materially adversely affect our financial condition and results of operations.

We may incur substantial losses and be subject to substantial liability claims as a result of our operations. Additionally, we may not be insured for, or our insurance may be inadequate to protect us against, these risks.
We are not insured against all risks. Losses and liabilities arising from uninsured and underinsured events could materially and adversely affect our business, financial condition or results of operations.
Our exploration and production activities are subject to all of the operating risks associated with drilling for and producing oil and natural gas, including the risk of fire, explosions, blowouts, surface cratering, uncontrollable flows of natural gas, oil and formation water, pipe or pipeline failures, abnormally pressured formations, casing collapses and environmental hazards such as oil spills, natural gas leaks, pipeline and tank ruptures or unauthorized discharges of toxic gases or other pollutants.
Any of these risks could adversely affect our ability to conduct operations or result in substantial loss to us as a result of claims for:
injury or loss of life;
damage to and destruction of property, natural resources and equipment;
pollution and other environmental damage;
regulatory investigations and penalties;
suspension of our operations; and
repair and remediation costs.
We may elect not to obtain insurance for any or all of these risks if we believe that the cost of available insurance is excessive relative to the risks presented. Moreover, insurance may not be available in the future at commercially reasonable costs and on commercially reasonable terms. Also, pollution and other environmental risks generally are not fully insurable. The occurrence of an event that is not covered or fully covered by insurance and any delay in the payment of insurance proceeds for covered events could have a material adverse effect on our business, financial condition and results of operations.
33

Our use of 2-D and 3-D seismic data is subject to interpretation and may not accurately identify the presence of oil and natural gas, which could adversely affect the results of our drilling operations.
Even when properly used and interpreted, 2-D and 3-D seismic data and visualization techniques are only tools used to assist geoscientists in identifying subsurface structures and hydrocarbon indicators and do not enable the interpreter to know whether hydrocarbons are, in fact, present in those structures. In addition, the use of 3-D seismic and other advanced technologies requires greater predrilling expenditures than traditional drilling strategies, and we could incur losses as a result of such expenditures. As a result, our drilling activities may not be successful or economical.
Our operations are substantially dependent on the availability of water. Restrictions on our ability to obtain water may have an adverse effect on our financial condition, results of operations and cash flows.
Water is an essential component of deep shale oil and natural gas production during both the drilling and hydraulic fracturing processes. Historically, we have been able to purchase water from local land owners for use in our operations. Drought conditions have led governmental authorities to restrict the use of water subject to their jurisdiction for hydraulic fracturing to protect local water supplies. If we are unable to obtain water to use in our operations from local sources, we may be unable to produce oil, natural gas and NGL economically, which could have an adverse effect on our financial condition, results of operations and cash flows.
Properties that we decide to drill may not yield oil, natural gas or NGL in commercially viable quantities.
Properties that we decide to drill that do not yield oil, natural gas or NGL in commercially viable quantities will adversely affect our results of operations and financial condition. There is no way to predict in advance of drilling and testing whether any particular prospect will yield oil or natural gas in sufficient quantities to recover drilling or completion costs or to be economically viable. The use of micro-seismic data and other technologies and the study of producing fields in the same area will not enable us to know conclusively prior to drilling whether oil or natural gas will be present or, if present, whether oil or natural gas will be present in commercial quantities. We cannot assure you that the analogies we draw from available data from other wells, more fully explored prospects or producing fields will be applicable to our drilling prospects. Further, our drilling operations may be curtailed, delayed or cancelled as a result of numerous factors, including:
unexpected drilling conditions;
title problems;
pressure or lost circulation in formations;
equipment failure or accidents;
adverse weather conditions;
compliance with environmental and other governmental or contractual requirements; and
increase in the cost of, shortages or delays in the availability of, electricity, supplies, materials, drilling or workover rigs, equipment and services.
We may be unable to make accretive acquisitionsThe unavailability or successfully integrate acquired businesses or assets,high cost of additional drilling rigs, equipment, supplies, personnel and any inability to do so may disrupt our business and hinderoilfield services could adversely affect our ability to grow.execute our exploration and development plans within our budget and on a timely basis.
InThe demand for qualified and experienced field personnel to drill wells and conduct field operations, geologists, geophysicists, engineers and other professionals in the future we may make acquisitions of oil and natural gas properties or businesses that complement or expand our current business. The successful acquisition of oil and gas properties requires an assessment of several factors, including:

recoverable reserves;
futureindustry can fluctuate significantly, often in correlation with oil, natural gas and NGL prices, causing periodic shortages. Historically, there have been shortages of drilling and their applicable differentials;
operating costs; and
potential environmentalworkover rigs, pipe and other liabilities.
The accuracyequipment as demand for rigs and equipment has increased along with the number of wells being drilled. We cannot predict whether these assessments is inherently uncertainconditions will exist in the future and, we may not be able to identify accretive acquisition opportunities. In connection with these assessments, we perform a review of the subject properties that we believe to be generally consistent with industry practices. Our reviewif so, what their timing and duration will not reveal all existingbe. Such shortages could delay or potential problems nor will it permitcause us to become sufficiently familiar with the properties to assess fully their deficiencies and capabilities. Reviews may not always be performed on every well, and environmental problems, such as groundwater contamination,incur significant expenditures that are not necessarily observable even when a review is performed. Even when problems are identified, the seller may be unwilling or unable to provide effective contractual protection against all or part of the problems. We often are not entitled to contractual indemnificationprovided for environmental liabilities and acquire properties on an “as is” basis. Even if we do identify accretive acquisition opportunities, we may not be able to complete the acquisition or do so on commercially acceptable terms.
The success of any completed acquisition will depend onin our ability to integrate effectively the acquired business into our existing operations. The process of integrating acquired businesses may involve unforeseen difficulties and may require a disproportionate amount of our managerial and financial resources. In addition, possible future acquisitions may be larger and for purchase prices significantly higher than those paid for earlier acquisitions. No assurance can be given that we will be able to identify additional suitable acquisition opportunities, negotiate acceptable terms, obtain financing for acquisitions on acceptable terms or successfully acquire identified targets. Our failure to achieve consolidation savings, to integrate the acquired businesses and assets into our existing operations successfully or to minimize any unforeseen operational difficultiescapital budget, which could have a material adverse effect on our business, financial condition or results of operations.
Our undeveloped acreage must be drilled before lease expiration to hold the acreage by production. In highly competitive markets for acreage, failure to drill sufficient wells to hold acreage could result in a substantial lease renewal cost or, if renewal is not feasible, loss of our lease and prospective drilling opportunities.
Unless production is established within the spacing units covering the undeveloped acres on which some of our drilling locations are identified, our leases for such acreage will expire. The cost to renew such leases is substantial and may increase significantly, and we may not be able to renew such leases on commercially reasonable terms or at all. For example, we would incur approximately $39.1 million if we were to extend all of our leases set to expire in the next three years without taking into account the drilling of wells and holding leases by production. As such, our actual drilling activities may differ materially from our current expectations, which could adversely affect our business. Moreover, many of our leases require lessor consent to
34

unitize, which may make it more difficult to hold our leases by production. Any reduction in our current drilling program, either through a reduction in capital expenditures or the unavailability of drilling rigs, could result in the loss of acreage through lease expirations. Our reserves and future production and, therefore, our future cash flow and income are highly dependent on successfully developing our undeveloped leasehold acreage and the loss of any leases could materially and adversely affect our ability to so develop such acreage. These risks are greater at times and in areas where the pace of our exploration and development activity slows.
Substantially all of our producing properties are located in the DJ Basin of Colorado, making us vulnerable to risks associated with operating in one major geographic area. Specifically, as the DJ Basin is an area of high industry activity, we may be unable to hire, train or retain qualified personnel needed to manage and operate our assets.
Substantially all of our producing properties are geographically concentrated in the DJ Basin of Colorado, an area in which industry activity has increased rapidly. At December 31, 2020, substantially all of our total estimated proved reserves were attributable to properties located in this area. As a result of this concentration, we may be disproportionately exposed to the impact of regional supply and demand factors or other regional events, delays or interruptions of production from wells in this area caused by governmental regulation, including at the state and local level, processing or transportation capacity constraints, market limitations, water shortages or other drought or extreme weather related conditions or interruption of the processing or transportation of oil, natural gas or NGL. For example, bottlenecks in processing and transportation that have occurred in some recent periods in the Wattenberg Field have negatively affected our results of operations. Similarly, the concentration of our producing assets within a small number of producing formations exposes us to risks, such as changes in field-wide rules that could adversely affect development activities or production relating to those formations. In addition, in areas where exploration and production activities are increasing, as has been the case in recent years in the Wattenberg Field, the demand for, and cost of, drilling rigs, equipment, supplies, personnel, and oilfield services increase. Shortages or the high cost of drilling rigs, equipment, supplies, personnel, or oilfield services could delay or adversely affect our development and exploration operations or cause us to incur significant expenditures that are not provided for in our capital forecast, which could have a material adverse effect on our business, financial condition, or results of operations.
Specifically, demand for qualified personnel in this area, and the cost to attract and retain such personnel, has increased over the past few years and may increase substantially in the future. Moreover, our competitors, including those operating in multiple basins, may be able to offer better compensation packages to attract and retain qualified personnel than we are able to offer. Any delay or inability to secure the personnel necessary for us to continue or complete our current and planned development activities could have a negative effect on production volumes or significantly increase costs, which could have a material adverse effect on our results of operations, liquidity and financial condition.
Risks Related to the Regulatory Environment
Changes in the legal and regulatory environment governing the oil and natural gas industry, particularly changes specific to the DJ Basin of Colorado, could have a material adverse effect on our business
Our business is subject to various forms of government regulation. Some local governments are adopting new requirements and restrictions on hydraulic fracturing and other oil and natural gas operations. Some local governments in Colorado, for instance, have amended their land use regulations to impose new requirements on oil and gas development, while other local governments have entered memoranda of agreement with oil and gas producers to accomplish the same objective. Beyond that, during the past few years, a total of five Colorado cities have passed voter initiatives temporarily or permanently prohibiting hydraulic fracturing. Since that time, local district courts have struck down the ordinances for certain of those Colorado cities, and such decisions were upheld by the Colorado Supreme Court in May 2016. Nevertheless, there is a continued risk that cities will adopt local ordinances that seek to regulate the time, place, and manner of hydraulic fracturing activities and oil and natural gas operations within their respective jurisdictions. For example, the town of Erie, Colorado first adopted a moratorium on oil and gas in July 2018, and on January 14, 2020, the City Council of Broomfield, Colorado unanimously approved an emergency noise ordinance that put the onus on a person or company to prove noise generated during restricted hours by such person or company is below Broomfield’s decibel standards.

In addition, in 2014, 2016 and 2018, opponents of hydraulic fracturing sought statewide ballot initiatives that would have restricted oil and gas development in Colorado. The 2014 initiatives were withdrawn in return for the creation of a task force to craft recommendations for minimizing land use conflicts over the location of oil and natural gas facilities, and none of the 2016 initiatives were successful. However, in 2018, the Colorado Secretary of State approved a citizen-initiated ballot measure, referred to as Prop. 112, for inclusion on the statewide voter ballot in November 2018. Although Prop. 112 was ultimately unsuccessful, similar efforts are likely to continue in the future, which, if successful, could result in dramatically reducing the area available for future oil and gas development in Colorado or outright banning oil and gas development in Colorado. We cannot predict the nature or outcome of future ballot initiatives or other similar efforts. If we are required to cease
35

operating in any of the areas in which we now operate as the result of bans or moratoria on drilling or related oilfield services activities, it could have a material effect on our business, financial condition, and results of operations.
In addition, our debt arrangements will impose certain limitations on our ability
Additionally, we are subject to enter into mergers or combination transactions. Our debt arrangements will also limit our ability to incur certain indebtedness, which could indirectly limit our ability to engage in acquisitions.
We may incur losses as a resultlaws and regulations concerning the location, spacing and permitting of title defects in the properties in which we invest.
It is our practice in acquiring oil and natural gas leases or interests not to incur the expense of retaining lawyers to examine the titlewells we drill, among other matters. In particular, our business utilizes a methodology available in Colorado known as “forced pooling,” which refers to the mineralability of a holder of an oil and natural gas interest atin a particular prospective drilling spacing unit to apply to the timeCOGCC for an order forcing all other holders of acquisition. Rather, we rely upon the judgmentoil and natural gas interests in such area into a common pool for purposes of lease brokers or land men who perform the fieldwork in examining recordsdeveloping that drilling spacing unit. This methodology is especially important for our operations in the appropriate governmental office before attemptingGreeley area, where there are many interest holders. Changes in the legal and regulatory environment governing our industry, particularly any changes to acquire a leaseColorado forced pooling procedures that make forced pooling more difficult to accomplish, could result in a specific mineral interest. The existence of a material title deficiency can render a lease worthlessincreased compliance costs and can adversely affect our business, financial condition and results of operations. SB181, enacted in April 2019, changed forced pooling requirements in the state of Colorado by requiring the consent of 45% of mineral interest holders, thus making it more difficult to include non-consenting individuals into statutory pooling agreements.

The enactment of Senate Bill 19-181 “Protect Public Welfare Oil and Gas Operations” increased the regulatory authority of local governments in Colorado over the surface impacts of oil and gas development, which could have a material adverse effect on our business.
In April 2019, SB181 became law, increasing the regulatory authority of local governments in Colorado over the surface impacts of oil and gas development in a necessary and reasonable manner, and in October 2020, Colorado’s AQCC adopted new rules targeting air emissions from upstream oil and gas operation. Among other things, SB181 (i) repeals a prior law restricting local government land use authority over oil and gas mineral extraction areas to areas designated by the COGCC, (ii) directs the AQCC to review its leak detection and repair rules and to adopt rules to minimize emissions of certain air pollutants, (iii) clarifies that local governments have authority to regulate the siting of oil and gas locations in a necessary and reasonable manner, including the ability to inspect oil and gas facilities, impose fines for leaks, spills, and emissions, and impose fees on operators or owners to cover regulation and enforcement costs, (iv) allows local governments or oil and gas operators to request a technical review board to evaluate the effect of the local government’s preliminary or final determination on the operator’s application, (v) repeals an exemption for oil and gas production from counties’ authority to regulate noise, (vi) alters forced pooling requirements by increasing the threshold to compel non-consenting individuals into statutory pooling agreements and (vii) prioritizes the protection of public health, safety, and welfare, the environment, and wildlife resources in the regulation of oil and gas development. Although industry trade associations opposed SB181, Extraction has demonstrated an ability to continue to successfully operate our business. However, the enactment of SB181 and the development and implementation of related rules and regulations, which is under way, could lead to delays and additional costs to our business.

We cannot predict the nature or outcome of future ballot initiatives, legislative actions or other similar efforts, or the effects of implementation of SB181 by local governments in Colorado. The enactment of new regulations resulting from SB181 may lead to delays and additional costs to our operations. Furthermore, if we are required to cease operating in any of the areas in which we now operate as the result of bans, onerous regulations or moratoria on drilling or related oilfield services activities, it could have a material effect on our business, financial condition, and results of operations.

The adoption of new rules by the Colorado Oil & Gas Conservation Commission to require, among other things, new siting criteria for any oil and gas locations that are within 2,000 feet from building units, could reduce the area available for future oil and gas development in Colorado and have a material adverse effect on our business.

Resulting from Colorado’s adoption of SB181 during 2019, the COGCC recently promulgated rules associated with that legislation that will, among other things, impose mandatory 2,000 foot setbacks for all schools and childcare centers, as well as new siting criteria for any oil and gas locations that are within 2,000 feet of building units. The rules additionally require local government permitting approval that could add additional timing and complexity and potentially lengthen the pace of the oil and gas permitting process. These new rules went into effect on January 15, 2021. We cannot predict the ultimate impact of implementation of these new rules, including the imposition of 2,000-foot siting zones, but their enactment may lead to delays and additional costs to our operations and financial condition. While we do typically obtain title opinions prior to commencing drilling operations on a lease or in a unit,reduce the failurearea available for future development of title may not be discovered until after a well is drilled, in which case we may lose the lease and the right to produce all or a portion of the minerals under the property.our operations.
We are subject to stringent environmental and health and safety laws and regulations that could expose us to significant costs and liabilities.
Our oil and natural gas exploration, development and production operations are subject to numerous stringent and complex federal, state and local laws and regulations governing safety and health aspects of our operations, the release, disposal or discharge of materials into the environment or otherwise relating to environmental protection. These laws and regulations may impose numerous obligations applicable to our operations including the acquisition of a permit before conducting drilling and
36

other regulated activities; the restriction of types, quantities and concentration of materials that may be released into the environment; the limitation or prohibition of drilling activities on certain lands lying within wilderness, wetlands and other protected areas; the application of specific health and safety criteria addressing worker protection; and the imposition of substantial liabilities for pollution resulting from our operations. Numerous governmentalGovernmental authorities, such as the EPA and analogous state agencies have the power to enforce compliance with these laws and regulations and the permits issued under them, often requiring costly actions. For example, on May 2, 2017, following an incident in Firestone, Colorado, the COGCC issued a Notice to Operators (the “Notice”) that, among other things, required operators of oil and natural gas wells in Colorado: (i) by May 30, 2017, toColorado re-inspect all existing flowlines and pipelines located within 1,000 feet of a defined “building unit,” which term includes residences andand/or properly abandon certain commercial facilities, to identify the well API number and tank battery location ID number associated with each line; (ii) by May 30, 2017, to inspect all existing flowlines and pipelines, regardless of distance to a “building unit,” to verify that any existing flowline or pipeline not in use, regardless of when it was installed or taken out of service, is abandoned in conformity with applicable rules; (iii) by June 30, 2017, to ensure and document that all flowlines within 1,000 feet of a “building unit” have integrity; and (iv) by June 30, 2017, to complete abandonment of any

flowline or pipeline not actively operated, regardless of distance to a “building unit,” and regardless of when it was installed or taken out of service, in conformity with the applicable rules and the Notice. In August 2017, the Governor of Colorado announced several policy initiatives designed to enhance public safety that are to be implemented through rulemaking or legislation.flowlines. On February 13, 2018, the COGCC approved new oil and natural gas flowline requirements, which include: (i) requirements for more-detailedincluded flowline tracking, location data, and record-keeping, for flowlines that carry fluids away from a specific oil and gas location; (ii) requirements that any flowlines not in use, but not yet abandoned, are locked and marked and must continue to undergo integrity testing, under the same standardsand locking and marking requirements, as active lines until abandonment, and any risers associated with abandoned flowlines must be cut below grade; (iii) more-detailed requirements for operators to demonstrate flowline integrity, including updated standards for integrity-testing lines, more testing options that align with newer technology, and the elimination of pressure-testing exemptions for low-pressure lines; and (iv) requirements for full operatorwell as participation in the Utility Notification Center of Colorado’s “one-call” program to ensure a centralized home for all data on flowline locations and access to that information through the established 811 “call-before-you-dig” system. Failure to comply with these laws and regulations may result in the assessment of sanctions, including administrative, civil or criminal penalties, the imposition of investigatory, remedial or corrective obligations, the occurrence of delays in permitting or development of projects and the issuance of orders limiting or prohibiting some or all of our operations in a particular area or forcing future compliance with environmental requirements.
The performance of our operations may result in significant environmental costs and liabilities due to our handling of petroleum hydrocarbons and other hazardous substances and wastes, as a result of air emissions and wastewater discharges related to our operations, and because of historical operations and waste disposal practices at our leased and owned properties. Spills or other releases of regulated substances could expose us to material losses, expenditures and liabilities under environmental laws and regulations. Under certain of such laws and regulations, we could be subject to strict, joint and several liability for the removal or remediation of previously released materials or property contamination, regardless of whether we were responsible for the release or contamination and even if our operations met previous standards in the industry at the time they were conducted. Changes in environmental laws and regulations occur frequently, and any changes that result in more stringent or costly well drilling, construction, completion or water management activities, air emissions control or waste handling, storage, transport, disposal or cleanup requirements could require us to make significant expenditures to attain and maintain compliance and may otherwise have a material adverse effect on our results of operations, competitive position or financial condition. We may not be able to recover some or any of our costs with respect to such developments from insurance. See “Business—Business and Properties—Regulation of Environmental and Safety and Health Matters” for a further description of environmental and safety and health laws and regulations that affect us.
The unavailability or high cost of additional drilling rigs, equipment, supplies, personnel and oilfield services could adversely affect our ability to execute our exploration and development plans within our budget and on a timely basis.
The demand for qualified and experienced field personnel to drill wells and conduct field operations, geologists, geophysicists, engineers and other professionals in the oil and natural gas industry can fluctuate significantly, often in correlation with oil, natural gas and NGL prices, causing periodic shortages. Historically, there have been shortages of drilling and workover rigs, pipe and other equipment as demand for rigs and equipment has increased along with the number of wells being drilled. We cannot predict whether these conditions will exist in the future and, if so, what their timing and duration will be. Such shortages could delay or cause us to incur significant expenditures that are not provided for in our capital budget, which could have a material adverse effect on our business, financial condition or results of operations.
Should we fail to comply with all applicable regulatory agency administered statutes, rules, regulations and orders, we could be subject to substantial penalties and fines.
Under the EPAct 2005, FERC has civil penalty authority under the NGA and NGPA to impose penalties for current violations of up to $1.0 million per day for each violation. FERC’s penalty authority is adjusted for inflation from time to time. FERC may also impose administrative and criminal remedies and disgorgement of profits associated with any violation. While our operations have not been regulated by FERC as a natural gas company under the NGA, FERC has adopted regulations that may subject certain of our otherwise non-FERC jurisdictional facilities to FERC annual reporting requirements. We also must comply with the anti-market manipulation rules enforced by FERC. Additional rules and regulations pertaining to those and other matters may be considered or adopted by FERC from time to time. Additionally, the FTC has regulations intended to prohibit market manipulation in the petroleum industry with authority to fine violators of the regulations civil penalties of up to $1.0 million per day, and the CFTC prohibits market manipulation in the markets regulated by the CFTC, including similar anti-manipulation authority with respect to oil swaps and futures contracts as that granted to the CFTC with respect to oil purchases and sales. The CFTC rules subject violators to a civil penalty of up to the greater of $1 million or triple the monetary gain to the person for each violation. Failure to comply with those regulations in the future could subject us to civil penalty liability, as described in “Business—Business and Properties—Regulation of the Oil and Gas Industry.”

We may be involved in legal proceedings that could result in substantial liabilities.
Like many oil and gas companies, we are from time to time involved in various legal and other proceedings, such as title, royalty or contractual disputes, regulatory compliance matters and personal injury or property damage matters, in the ordinary course of our business. Additionally, citizen groups have brought and, in certain instances, may continue to bring legal proceedings against us to challenge our ability to receive environmental permits that we need to operate. Such legal proceedings are inherently uncertain and their results cannot be predicted. Regardless of the outcome, such proceedings could have an adverse impact on us because of legal costs, diversion of management and other personnel and other factors. In addition, it is possible that a resolution of one or more such proceedings could result in liability, loss of necessary environmental permits, penalties or sanctions, as well as judgments, consent decrees or orders requiring a change in our business practices, which could materially and adversely affect our business, operating results and financial condition. Accruals for such liability, penalties or sanctions may be insufficient. Judgments and estimates to determine accruals or range of losses related to legal and other proceedings could change from one period to the next, and such changes could be material.
Climate change legislation or regulations restricting emissions
37

Climate change continues to attract considerable public and scientific attention. As a result, numerous proposals have been made and could continue to be made at the international, national, regional and state levels of government to monitor and limit emissions of GHG. These efforts have included consideration of cap-and-trade programs, carbon taxes and GHG reporting and tracking programs, and regulations that directly limit GHG emissions from certain sources. 
At the federal level, no comprehensive climate change legislation has been implemented to date. However, the EPA has adopted rules under authority of the CAA that, among other things, establish PSD construction and Title V permit reviews for GHG emissions from certain large stationary sources that are also potential major sources of certain principal pollutant emissions, which reviews could require meeting “best available control technology” standards for those emissions. In addition, the EPA has adopted rules requiring the monitoring and annual reporting of GHG emissions from certain petroleum and natural gas system sources in the United States, including, among other things, onshore producing facilities, which include certain of our operations. Federal agencies also have begun directly regulating emissions of methane from oil and natural gas operations, with the EPA publishing NSPS Subpart OOOOa standards in June 2016 that require certain new, modified or reconstructed facilities in the oil and natural gas sector to reduce these methane gas and volatile organic compound emissions and the BLM publishing requirements in November 2016 to reduce methane emissions from venting, flaring, and leaking on public lands. Both of the EPA's and BLM's methane rules have been subject to attempted stays of the rules or parts thereof by the respective agencies and rulemakings that would further amend those rules also have been proposed. THe future implementation of these two methane rules are uncertain but remain a possibility. Additionally, in December 2015, the United States joined the international community at the 21st Conference of the Parties of the United Nations Framework Convention on Climate Change in Paris, France preparing an agreement requiring member countries to review and “represent a progression” in their intended nationally determined contributions, which set GHG emission reduction goals every five years beginning in 2020. This “Paris Agreement” was signed by the United States in April 2016 and entered into force in November 2016; however, this agreement does not create any binding obligations for nations to limit their GHG emissions, but rather includes pledges to voluntarily limit or reduce future emissions. In follow-up to an earlier announcement by President Trump, in August 2017, the U.S. Department officially informed the United Nations of the intent of the United States to withdraw from the Paris Agreement. The Paris Agreement provides for a four-year exit process beginning when it took effect in November 2016, which would result in an effective exit date of November 2020. The United States’ adherence to the exit process and/or the terms on which the United States may re-enter the Paris Agreement or a separately negotiated agreement are unclear at this time.
     The adoption and implementation of any international, federal or state legislation or regulations that require reporting of GHG or otherwise limit emissions of GHG from, our equipment and operations could result in increased costs to reduce emissions of GHG associated with our operations as well as delays or restrictions in our ability to permit GHG emissions from new or modified sources. In addition, substantial limitations on GHG emissions could adversely affect demand for the oil, natural gas and NGL we produce and lower the value of our reserves, which devaluation could be significant. One or more of these developments could have a materially adverse effect on our business, financial condition and results of operations. Finally, notwithstanding potential risks related to climate change, the International Energy Agency, an autonomous intergovernmental organization involved in international energy policy, estimates that global energy demand will continue to rise and will not peak until after 2040 and oil and gas will continued to represent a substantial percentage of global energy use over that time. However, recent activism directed at shifting funding away from companies with energy-related assets could result in limitations or restrictions on certain sources of funding for the energy sector.

Federal, state and local legislative and regulatory initiatives relating to hydraulic fracturing could result in increased costs and additional operating restrictions or delays in the completion of oil and natural gas wells and adversely affect our production.
Hydraulic fracturing is an important and common practice that is used to stimulate production of natural gas and oil from dense subsurface rock formations. We regularly use hydraulic fracturing as part of our operations. Hydraulic fracturing involves the injection of water, sand or alternative proppant and chemical additives under pressure into targeted geological formations to fracture the surrounding rock and stimulate production. Hydraulic fracturing is typically regulated by state oil and natural gas commissions or similar state agencies but several federal agencies have asserted regulatory authority over certain aspects of the process. In addition, in December 2016, the EPA released its final report on the potential impacts of hydraulic fracturing on drinking water resources, concluding that “water cycle” activities associated with hydraulic fracturing may impact drinking water resources under certain circumstances. Also, from time to time, the U.S. Congress has considered, but not adopted, legislation to provide for federal regulation of hydraulic fracturing and to require disclosure of the chemicals used in the fracturing process. At the state level, Colorado, where we conduct operations, is among the states that has adopted, and other states are considering adopting, regulations that impose new or more stringent permitting, disclosure or well-construction requirements on hydraulic fracturing operations. States may also elect to prohibit high volume hydraulic fracturing altogether, following the approach taken by the State of New York. In addition to state laws, local land use restrictions may restrict drilling or the hydraulic fracturing and cities may adopt local ordinances allowing hydraulic fracturing activities within their jurisdictions but regulating the time, place and manner of those activities. If new or more stringent federal, state or local legal restrictions relating to the hydraulic fracturing process are adopted in areas where we operate, including, for example, on federal and American Indian lands, we could incur potentially significant added cost to comply with such requirements, experience delays or curtailment in the pursuit of exploration, development or production activities, and perhaps even be precluded from drilling wells.

Moreover, because most of our operations are conducted in a particular area, the DJ Basin in Colorado, legal restrictions imposed in that area will have a significantly greater adverse effect than if we had our operations spread out amongst several diverse geographic areas. Consequently, in the event that local or state restrictions or prohibitions are adopted in the DJ Basin in Colorado that impose more stringent limitations on the production and development of oil and natural gas, we may incur significant costs to comply with such requirements or may experience delays or curtailment in the pursuit of exploration, development, or production activities, and possibly be limited or precluded in the drilling of wells or in the amounts that we are ultimately able to produce from our reserves. Any such increased costs, delays, cessations, restrictions or prohibitions could have a material adverse effect on our business, prospects, results of operations, financial condition, and liquidity.
At the local level, some municipalities and local governments have adopted or are considering bans on hydraulic fracturing. Beginning in 2012, voters in the cities of Fort Collins, Boulder, Longmont, Broomfield and Lafayette, Colorado approved bans of varying length on hydraulic fracturing within their respective city limits. In 2014, Boulder and Larimer county lower courts overturned the bans. The cities of Longmont and Fort Collins appealed the decisions. In August 2015, the Court of Appeals requested that the Colorado Supreme Court rule on the issue. The Colorado Supreme Court struck down the Fort Collins and Longmont bans in May 2016. Nonetheless, extended moratoria, like that put in place by Boulder County in December 2016, remain a threat to oil and gas operations in Colorado.
Please read “Business—Business and Properties—Regulation of Environmental and Safety and Health Matters—Hydraulic Fracturing Activities” for a further description of the laws and regulations relating to hydraulic fracturing that affect us.
Competition in the oil and natural gas industry is intense, making it more difficult for us to acquire properties and market oil or natural gas.
Our ability to acquire additional prospects and to find and develop reserves in the future will depend on our ability to evaluate and select suitable properties and to consummate transactions in a highly competitive environment for acquiring properties, marketing oil and natural gas and securing trained personnel. Also, there is substantial competition for capital available for investment in the oil and natural gas industry. We may not be able to compete successfully in the future in acquiring prospective reserves, developing reserves, marketing hydrocarbons, and raising additional capital, which could have a material adverse effect on our business.
Our undeveloped acreage must be drilled before lease expiration to hold the acreage by production. In highly competitive markets for acreage, failure to drill sufficient wells to hold acreage could result in a substantial lease renewal cost or, if renewal is not feasible, loss of our lease and prospective drilling opportunities.
Unless production is established within the spacing units covering the undeveloped acres on which some of our drilling locations are identified, our leases for such acreage will expire. The cost to renew such leases may increase significantly, and we may not be able to renew such leases on commercially reasonable terms or at all. As such, our actual drilling activities may differ materially from our current expectations, which could adversely affect our business. These risks are greater at times and in areas where the pace of our exploration and development activity slows.

Declining general economic, business or industry conditions may have a material adverse effect on our results of operations, liquidity and financial condition.
Concerns over global economic conditions, energy costs, geopolitical issues, inflation, the availability and cost of credit and the United States financial market have contributed to increased economic uncertainty and diminished expectations for the global economy. In addition, continued hostilities in the Middle East and the occurrence or threat of terrorist attacks in the United States or other countries could adversely affect the global economy. These factors, combined with volatile commodity prices, declining business and consumer confidence and increased unemployment, have precipitated an economic slowdown and a recession. Concerns about global economic growth have had a significant adverse impact on global financial markets and commodity prices. If the economic climate in the United States or abroad deteriorates, worldwide demand for petroleum products could diminish, which could impact the price at which we can sell our production, affect the ability of our vendors, suppliers and customers to continue operations and ultimately adversely impact our results of operations, liquidity and financial condition.
The loss of senior management or technical personnel could adversely affect operations.
We depend on the services of our senior management and technical personnel. We do not maintain, nor do we plan to obtain, any insurance against the loss of any of these individuals. The loss of the services of our senior management or technical personnel could have a material adverse effect on our business, financial condition and results of operations.
We are susceptible to the potential difficulties associated with rapid growth and expansion and have a limited operating history.
We have grown rapidly since we began operations in late 2012. Our management believes that our future success depends on our ability to manage the rapid growth that we have experienced and the demands from increased responsibility on management personnel. The following factors could present difficulties:
increased responsibilities for our executive level personnel;
increased administrative burden;
increased capital requirements; and
increased organizational challenges common to large, expansive operations.
Our operating results could be adversely affected if we do not successfully manage these potential difficulties. The historical financial information incorporated herein is not necessarily indicative of the results that may be realized in the future. In addition, our operating history is limited and the results from our current producing wells are not necessarily indicative of success from our future drilling operations.
Increases in interest rates could adversely affect our business.
Our business and operating results can be harmed by factors such as the availability, terms and cost of capital, increases in interest rates or a reduction in credit rating. These changes could cause our cost of doing business to increase, limit our ability to pursue acquisition opportunities, reduce cash flow used for drilling and place us at a competitive disadvantage. Potential disruptions and volatility in the global financial markets may lead to a contraction in credit availability impacting our ability to finance our operations. We require continued access to capital. A significant reduction in cash flows from operations or the availability of credit could materially and adversely affect our ability to achieve our planned growth and operating results.
Our use of 2-D and 3-D seismic data is subject to interpretation and may not accurately identify the presence of oil and natural gas, which could adversely affect the results of our drilling operations.
Even when properly used and interpreted, 2-D and 3-D seismic data and visualization techniques are only tools used to assist geoscientists in identifying subsurface structures and hydrocarbon indicators and do not enable the interpreter to know whether hydrocarbons are, in fact, present in those structures. In addition, the use of 3-D seismic and other advanced technologies requires greater predrilling expenditures than traditional drilling strategies, and we could incur losses as a result of such expenditures. As a result, our drilling activities may not be successful or economical.

Adverse weather conditions may negatively affect our operating results and our ability to conduct drilling activities.
Adverse weather conditions may cause, among other things, increases in the costs of, and delays in, drilling or completing new wells, power failures, temporary shut-in of production and difficulties in the transportation of our oil, natural gas and NGL. Any decreases in production due to poor weather conditions will have an adverse effect on our revenues, which will in turn negatively affect our cash flow from operations.
Our operations are substantially dependent on the availability of water. Restrictions on our ability to obtain water may have an adverse effect on our financial condition, results of operations and cash flows.
Water is an essential component of deep shale oil and natural gas production during both the drilling and hydraulic fracturing processes. Historically, we have been able to purchase water from local land owners for use in our operations. Drought conditions have led governmental authorities to restrict the use of water subject to their jurisdiction for hydraulic fracturing to protect local water supplies. If we are unable to obtain water to use in our operations from local sources, we may be unable to produce oil, natural gas and NGL economically, which could have an adverse effect on our financial condition, results of operations and cash flows.
Restrictions on drilling activities intended to protect certain species of wildlife and natural resources may adversely affect our ability to conduct drilling activities areas where we operate.
Oil and natural gas operations in our operating areas may be adversely affected by seasonal or permanent restrictions on drilling activities designed to protect various wildlife and natural resources. Seasonal restrictions may limit our ability to operate in protected areas and can intensify competition for drilling rigs, oilfield equipment, services, supplies and qualified personnel, which may lead to periodic shortages when drilling is allowed. These constraints and the resulting shortages or high costs could delay our operations or materially increase our operating and capital costs. Permanent restrictions imposed to protect endangered species could prohibit drilling in certain areas or require the implementation of expensive mitigation measures. The designation of previously unprotected species in areas where we operate as threatened or endangered could cause us to incur increased costs arising from species protection measures or could result in limitations on our exploration and production activities that could have a material adverse impact on our ability to develop and produce our reserves.
Regulation of greenhouse gases and climate change could have a negative impact on our business.
38

Some scientific studies have suggested that emissions of greenhouse gases may be contributing to warming of the earth’s atmosphere and other climatic changes. Such studies have resulted in increased local, state, regional, national, and international attention and actions relating to issues of climate change and the effect of GHG emissions, particularly emissions from fossil fuels. For example, the United States has been involved in international negotiations regarding greenhouse gas reductions under the United Nations Framework Convention on Climate Change (“UNFCCC”). The U.S. was among 195 nations that participated in the creation of an international accord in December 2015, the Paris Agreement, with the objective of limiting greenhouse gas emissions. The Paris Agreement entered into force on November 4, 2016 and, as of January 2020, had been ratified by 187 of the 197 parties to the UNFCC. The EPA has also taken action under the CAA to regulate greenhouse gas emissions. In addition, a number of states have either proposed or implemented restrictions on greenhouse gas emissions. International accords such as the Paris Agreement may result in additional regulations to control greenhouse gas emissions. Other developments focused on restricting GHG emissions include but are not limited to the Kyoto Protocol; the European Union Emission Trading System; the United Kingdom’s Carbon Reduction Commitment; and, in the U.S., the Regional Greenhouse Gas Initiative, the Western Regional Climate Action Initiative, and various state programs.
The enactment of derivatives legislation and associated regulations could have an adverse effect on our ability to use derivative instruments to reduce the effect of commodity price, interest rate and other risks associated with our business.
The Dodd-Frank Act, enacted on July 21, 2010, established federal oversight and regulation of the over-the-counter derivatives market and of entities, such as us, that participate in that market. The Dodd-Frank Act requires the CFTC and the SEC to promulgate rules and regulations implementing the Dodd-Frank Act. In its rulemaking underWhile many rules implementing the Dodd-Frank Act have been finalized, some have not, and, as a result, the final form of the regulatory regime for commodity derivatives remains uncertain. Position limits for certain energy commodity futures and options contracts, as well as economically equivalent swaps, futures and options, are subject to ongoing rulemaking activities. With regard to position limits, in November 2013,January 2020, the CFTC withdrew the 2013 proposal, the 2016 supplement, and the 2016 reproposal, and issued a new proposed new rules that would placerule which includes limits on positions in (1) certain core“Core Referenced Futures Contracts,” including contracts for several energy commodities; (2) futures and equivalent swaps contracts foroptions on futures that are directly or indirectly linked to certain physical commodities, subjectthe price of a Core Referenced Futures Contract, or to exceptionsthe same commodity for certaindelivery at the same location as specified in that Core Referenced Futures Contract; and (3) economically equivalent swaps. The proposal also includes exemptions from position limits for bona fide hedging transactions.activities. As these new position limit rules are not yet final, the impact of those provisions on us is uncertain at this time.
The Dodd-Frank Act and CFTC rules also will require us, in connection with certain derivatives activities, to comply with clearing and trade-execution requirements (or to take steps to qualify for an exemption to such requirements). In addition, the CFTC and certain banking regulators have recently adopted final rules establishing minimum margin requirements for uncleared swaps. Although we expect to qualify for the end-user exception to the mandatory clearing, trade-execution and margin requirements for swaps entered to hedge our commercial risks, the application of such requirements to other market participants, such as swap dealers, may change the cost and availability of the swaps that we use for hedging. In addition, if any of our swaps do not qualify for the commercial end-user exception, posting of collateral could impact our liquidity and reduce cash available to us for capital expenditures, therefore reducing our ability to execute hedges to reduce risk and protect cash flow. It is not possible at this time to predict with certainty the full effects of the Dodd-Frank Act and CFTC rules on us or the timing of such effects. The Dodd-Frank Act and any new regulations could significantly increase the cost of derivative contracts, materially alter the terms of derivative contracts, reduce the availability of derivatives to protect against risks we encounter, and reduce our ability to monetize or restructure our existing derivative contracts. If we reduce our use of derivatives as a result of the Dodd-Frank Act and CFTC rules, our results of operations may become more volatile and our cash flows may be less predictable, which could adversely affect our ability to plan for and fund capital expenditures. Finally, the Dodd-Frank Act was intended, in part, to reduce the volatility of oil, natural gas and NGL prices, which some legislators attributed to speculative trading in derivatives and commodity instruments related to oil, natural gas and NGL. Our revenues could therefore be adversely affected if a consequence of the Dodd-Frank Act and CFTC rules is to lower commodity prices. Any of these consequences could have a material and adverse effect on us, our financial condition or our results of operations. In addition, the European Union and other non-U.S. jurisdictions are implementing regulations with respect to the derivatives market. To the extent we transact with counterparties in foreign jurisdictions, we may become subject to such regulations, the impact of which is not clear at this time.

Risks Related to Capital
Recent changes in United States federal income tax law may have an adverse effect on our cash flows, results of operations or financial condition overall.
The final version of the tax reform bill commonly known as the Tax Cuts and Jobs Act (the "TCJA") signed into law on December 22, 2017 may affect our cash flows, results of operations and financial condition. Among other items, the TCJA repealed the deduction for certain U.S. Production activities and provided for a new limitation on the deduction for interest expense. Given the scope of this law and the potential interdependency of its changes, it is difficult at this time to assess whether the overall effect of the TCJA will be cumulatively positive or negative for our earnings and cash flow, but such changes may adversely impact our financial results.
Certain federal income tax deductions currently available with respect to natural gas and oilOur exploration and development projects require substantial capital expenditures. We may be eliminated asunable to obtain required capital or financing on satisfactory terms, which could lead to a result of future legislation.
In past years, legislation has been proposed that would, if enacted into law, make significant changes to U.S. tax laws, including to certain key U.S. federal income tax provisions currently available to oil and gas companies. Although none of these changes were included in the TCJA, future adverse changes could include, but are not limited to, (i) the repeal of the percentage depletion allowance for oil and gas properties, (ii) the elimination of current deductions for intangible drilling and development costs, and (iii) an extension of the amortization period for certain geological and geophysical expenditures. Congress could consider, and could include, some or all of these proposals as part of future tax reform legislation. The passage of any legislation as a result of these proposals or any similar changes in U.S. federal income tax laws could eliminate or postpone certain tax deductions that currently are available with respect to oil and gas development, or increase costs, and any such changes could have an adverse effect on the Company’s financial position, results of operations and cash flows.
We may not be able to keep pace with technological developmentsdecline in our industry.reserves.

39

The oil and natural gas industry is characterized by rapidcapital intensive. We make and significant technological advancementsexpect to continue to make substantial capital expenditures for the exploitation, development and introductionsacquisition of new products and services using new technologies. As others use or develop new technologies, we may be placed at a competitive disadvantage or may be forced by competitive pressures to implement those new technologies at substantial costs. In addition, other oil and natural gas reserves. In 2021, we plan to invest $140 million to $180 million for drilling and completion of operated and non-operated wells. We expect to fund our 2021 capital expenditures with borrowings under our RBL Credit Facility, cash flows from operations and possibly through asset sales or additional capital markets transactions. The actual amount and timing of our future capital expenditures may differ materially from our estimates as a result of, among other things, oil, natural gas and NGL prices, actual drilling results, the availability of drilling rigs and other services and equipment, and regulatory, technological and competitive developments. A reduction in commodity prices from current levels may result in a decrease in our actual capital expenditures, which would negatively impact our ability to grow production. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources” in Item 7. in Part I of this Annual Report.

A negative shift in investor sentiment of the oil and gas industry could have adverse effects on our ability to raise debt and equity capital and on our operations.

Certain segments of the investor community have developed negative sentiment towards investing in our industry. Recent equity returns in the sector versus other industry sectors have led to lower oil and gas representation in certain key equity market indices. In addition, some investors, including investment advisors and certain sovereign wealth funds, pension funds, university endowments and family foundations, have stated policies to disinvest in the oil and gas sector based on their social and environmental considerations. Certain other stakeholders have also pressured commercial and investment banks to stop financing oil and gas production and related infrastructure projects. Such developments, including environmental activism and initiatives aimed at limiting climate change and reducing air pollution, could result in downward pressure on the stock prices of oil and gas companies, including ours. This may also potentially result in a reduction of available capital funding for potential development projects, impacting our future financial results.
Additionally, negative public perception regarding us and/or our industry may lead to increased regulatory scrutiny, which may, in turn, lead to new state and federal safety and environmental laws, regulations, guidelines and enforcement interpretations. Additionally, environmental groups, landowners, local groups and other advocates may oppose our operations through organized protests, attempts to block or sabotage our operations or those of our midstream transportation providers, intervene in regulatory or administrative proceedings involving our assets or those of our midstream transportation providers, or file lawsuits or other actions designed to prevent, disrupt or delay the development or operation of our assets and business or those of our midstream transportation providers. These actions may cause operational delays or restrictions, increased operating costs, additional regulatory burdens and increased risk of litigation. Moreover, governmental authorities exercise considerable discretion in the timing and scope of permit issuance and the public may engage in the permitting process, including through intervention in the courts. Negative public perception could cause the permits we require to conduct our operations to be withheld, delayed or burdened by requirements that restrict our ability to profitably conduct our business. Recently, activists concerned about the potential effects of climate change have directed their attention towards sources of funding for fossil-fuel energy companies, which has resulted in certain financial institutions, funds and other sources of capital restricting or eliminating their investment in energy-related activities. Ultimately, this could make it more difficult to secure funding for exploration and production activities.
Declining general economic, business or industry conditions may have greater financial, technical and personnel resources that allow them to enjoy technological advantages and that may in the future allow them to implement new technologies before we can. We may not be able to respond to these competitive pressures or implement new technologiesa material adverse effect on a timely basis or at an acceptable cost. If one or more of the technologies we use now or in the future were to become obsolete, our business, financial condition or results of operations, liquidity and financial condition.
Concerns over global economic conditions, energy costs, geopolitical issues, inflation, the availability and cost of credit and the United States financial market have contributed to increased economic uncertainty and diminished expectations for the global economy. In addition, continued hostilities in the Middle East and the occurrence or threat of terrorist attacks in the United States or other countries could adversely affect the global economy. These factors, combined with volatile commodity prices, declining business and consumer confidence and increased unemployment, have precipitated an economic slowdown and a recession. Concerns about global economic growth have had a significant adverse impact on global financial markets and commodity prices. If the economic climate in the United States or abroad deteriorates, worldwide demand for petroleum products could diminish, which could impact the price at which we can sell our production, affect the ability of our vendors, suppliers and customers to continue operations and ultimately adversely impact our results of operations, liquidity and financial condition.
We may be materiallyunable to access the equity or debt capital markets, including the market for senior unsecured notes, to meet our obligations.
Declines in commodity prices may cause the financial markets to exert downward pressure on stock prices and adversely affected.

Risks Related to Debt
Restrictions in our existing and future debt agreements could limit our growth and our ability to engage in certain activities.
Our existing and future debt arrangements, including the RBL Credit Facility, contain or may contain a number of significant covenants, including restrictive covenants that may limit our ability to, among other things:
incur additional indebtedness;
sell assets;
make loans to others;
make certain acquisitions and investments;
enter into mergers, consolidations or other transactions resulting in the transfer of all or substantially all of our assets;
make certain payments, including paying dividends or distributions in respect of our equity;
hedge future production or interest rates;
redeem and prepay other debt;
incur liens; and
engage in certain other transactions without the prior consent of the lenders.
In particular,addition, our implementationdebt arrangements require us to maintain certain financial ratios or to reduce our indebtedness if we are unable to comply with such ratios. These restrictions may also limit our ability to obtain future financings to withstand a future downturn in our business or the economy in general, or to otherwise conduct necessary corporate activities. We may also be prevented from taking advantage of various proceduresbusiness opportunities that arise because of the limitations that the restrictive covenants under our debt arrangements will impose on us.
Our RBL Credit Facility limits the amount we can borrow up to the lower of our aggregate lender commitments and controlsa borrowing base amount, which the lenders, in their sole discretion, will determine on a semi-annual basis based upon projected revenues from the oil and natural gas properties securing our loan. The lenders will be able to monitorunilaterally adjust the borrowing base and mitigate security threats andthe borrowings permitted to be outstanding under our RBL Credit Facility. We will be required to repay any outstanding borrowings in excess of the then current borrowing base. Any increase security forin the borrowing base requires the consent of the lenders holding 100% of the commitments. If the requisite number of lenders does not agree to a proposed borrowing base, then the borrowing base will be the highest borrowing base acceptable to such lenders. Our borrowing base is currently $500.0 million, subject to the current elected lending commitments of $500.0 million.
A breach of any covenant in our information, facilities and infrastructure mayRBL Credit Facility or any other debt agreement would result in increaseda default after any applicable grace periods. A default, if not waived, could result in acceleration of the indebtedness outstanding under the facility and a default with respect to, and an acceleration of, the indebtedness outstanding under other debt agreements. The accelerated indebtedness would become immediately due and payable. If that occurs, we may not be able to make all of the required payments or borrow sufficient funds to refinance such indebtedness. Even if new financing were available at that time, it may not be on terms that are acceptable to us. In addition, our obligations under our RBL Credit Facility are secured by perfected first priority liens and security interests on substantially all of our assets, including mortgage liens on oil and natural gas properties having at least 90% of the reserve value as determined by reserve reports, and if we are unable to repay our indebtedness under the RBL Credit Facility, the lenders could seek to foreclose on our assets.
41

The borrowing base under our RBL Credit Facility may be reduced in connection with declines in commodity prices, which could hinder or prevent us from meeting our future capital needs.
The borrowing base under our RBL Credit Facility is currently $500.0 million, and operating costs. Moreover, there can be no assurance that such procedurescurrent elected lending commitments under the RBL Credit Facility are $500.0 million. Our borrowing base is redetermined semiannually on each May 1 and controls will be sufficient to prevent security breaches from occurring. If any ofNovember 1 (or once per year between these security breaches weredates) based on certain factors, including our reserves and hedge position, with the next borrowing base redetermination scheduled to occur in May 2021. Our borrowing base may decrease as a result of declines in natural gas, NGLs, and oil prices, or as a result of operating difficulties, declines in reserves, lending requirements or regulations, the issuance of new indebtedness or other reasons. In the event of a decrease in our borrowing base due to declines in commodity prices or otherwise, we may be unable to meet our obligations as they come due and could leadbe required to lossesrepay any indebtedness in excess of financial assets, sensitive information, critical infrastructurethe redetermined borrowing base. In addition, we may be unable to access the equity or capabilities essentialdebt capital markets, including the market for senior unsecured notes, to meet our operationsobligations. As a result, we may be unable to implement our drilling and development plan, make acquisitions or otherwise carry out our business plan, which could have a material adverse effect on our reputation, financial position, results of operations or cash flows. Cybersecurity attacks in particular are becoming more sophisticated and include, but are not limited to, malicious software, attempts to gain unauthorized access to data and systems, and other electronic security breaches that could lead to disruptions in critical systems, unauthorized release of confidential or otherwise protected information, and corruption of data. These events could lead to financial losses from remedial actions, loss of business or potential liability. In addition, destructive forms of protest and opposition by activists and other disruptions, including acts of sabotage or eco-terrorism, against oil and gas production and activities could potentially result in damage or injury to people, property or the environment or lead to extended interruptions of our operations, adversely affecting our financial condition and results of operations.operations and our ability to service our indebtedness.
LossAvailability, terms and cost of our information and computer systemscapital, increases in interest rates or a reduction in credit rating could adversely affect our business.

Our business and operating results can be harmed by factors such as the availability, terms and cost of capital, increases in interest rates or a reduction in credit rating. These changes could cause our cost of doing business to increase, limit our ability to pursue acquisition opportunities, reduce cash flow used for drilling and place us at a competitive disadvantage. Potential disruptions and volatility in the global financial markets may lead to a contraction in credit availability impacting our ability to finance our operations. We are dependentrequire continued access to capital. A significant reduction in cash flows from operations or the availability of credit could materially and adversely affect our ability to achieve our planned growth and operating results.

We may not be able to generate sufficient cash to service all of our indebtedness and may be forced to take other actions to satisfy our obligations under our debt arrangements, which may not be successful.

Our ability to make scheduled payments on or to refinance our indebtedness obligations, including our RBL Credit Facility, depends on our information systemsfinancial condition and computer-based programs, includingoperating performance, which are subject to prevailing economic and competitive conditions and certain financial, business and other factors beyond our well operations information, seismic data, electronic data processing and accounting data.control. If any of such programs or systems were to fail or

If our cash flows and capital resources are insufficient to fund debt service obligations, we may be forced to reduce or delay investments and capital expenditures, sell assets, seek additional capital or restructure or refinance indebtedness. Our ability to restructure or refinance indebtedness will depend on the condition of the capital markets and our financial condition at such time. Any refinancing of indebtedness could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict business operations. The terms of existing or future debt arrangements may restrict us from adopting some of these alternatives. In addition, any failure to make payments of interest and principal on outstanding indebtedness on a timely basis could harm our ability to incur additional indebtedness. In the absence of sufficient cash flows and capital resources, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet debt service and other obligations. Our RBL Credit Facility currently restricts our ability to dispose of assets and our use of the proceeds from such disposition. We may not be able to consummate those dispositions, and the proceeds of any such disposition may not be adequate to meet any debt service obligations then due. These alternative measures may not be successful and may not permit us to meet scheduled debt service obligations.

As a public company, including compliance with the reporting requirementsresult of the Securities Exchange ActRestatement, we have become subject to possible additional costs for accounting and legal fees in connection with or related to the restatement and additional risks and uncertainties, including, among others, the increased possibility of 1934, as amended (the “Exchange Act”), and the requirements of the Sarbanes-Oxley Act, may strain our resources, increase our costs and distract management, and we may be unable to comply with these requirements inlegal proceedings, shareholder lawsuits or a timely or cost-effective manner.
We completed our IPO in October 2016. As a public company, we must comply with various laws, regulations and requirements, certain corporate governance provisions of the Sarbanes-Oxley Act, related regulations ofreview by the SEC and the requirements of the NASDAQ, with which we were not required to comply as a private company. Complying with these statutes, regulations and requirements will occupy a significant amount of time of our board of directors and management and will significantly increase our costs and expenses. We are now required to:
institute a more comprehensive compliance function;
comply with rules promulgated by the NASDAQ;
continue to prepare and distribute periodic public reports in compliance with our obligations under the federal securities laws;
establish new internal policies, such as those relating to insider trading; and
involve and retain to a greater degree outside counsel and accountants in the above activities.
Any failure to develop or maintain effective internal controls, or difficulties encountered in implementing or improving our internal controls, could harm our operating results or cause us to fail to meet our reporting obligations. Moreover, if we are not able to comply with the requirements of Section 404 in a timely manner, or if in the future we or our independent registered public accounting firm identifies deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses, the market price of our stock could decline, and we could be subject to sanctions or investigations by the SEC or other regulatory authorities,bodies, which would require additional financial and management resources.
In addition, we expect that being a public company subject to these rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified individuals to serve on our board of directors or as executive officers.
If we fail to develop or maintain an effective system of internal controls, we may not be able to accurately report our financial results or prevent fraud. If one or more material weaknesses emerge related to financial reporting, or if we otherwise fail to establish and maintain effective internal control over financial reporting, our ability to accurately report our financial results could be adversely affected. As a result, current and potential stockholders could lose confidence in our financial reporting, which would harm our business and the trading price of our common stock.
Effective internal controls are necessary for us to provide reliable financial reports, prevent fraud and operate successfully as a public company. If we cannot provide reliable financial reports or prevent fraud, our reputation and operating results would be harmed. We cannot be certain that our efforts to develop and maintain our internal controls will be successful, that we will be able to maintain adequate controls over our financial processes and reporting in the future or that we will be able to comply with our obligations under Section 404 of the Sarbanes-Oxley Act of 2002. Any failure to develop or maintain effective internal controls, or difficulties encountered in implementing or improving our internal controls, could harm our operating results or cause us to fail to meet our reporting obligations. Ineffective internal controls could also cause investors to lose confidence in our reported financial information and could subject us to civil or criminal penalties, shareholder class actions or derivative actions. We could face monetary judgments,
42

penalties or other sanctions that could have a material adverse effect on our business, financial condition and results of operations and could cause our stock price to decline.

If we fail to meet the requirements for continued listing on the NASDAQ Global Select Market, our common stock could be delisted, which would likely have a negative effectdecrease the liquidity of our common stock and our ability to raise additional capital.
Our common stock was traded on the NASDAQ under the symbol “XOG” until June 25, 2020. On June 16, 2020, we received a letter from the NASDAQ notifying us that, as a result of the Chapter 11 Cases and in accordance with NASDAQ rules, our securities would be delisted at the opening of business on June 25, 2020. On June 25, 2020, our common stock began to be quoted on the Pink Open Market under the symbol “XOGAQ”. In connection with our emergence from bankruptcy, our common stock was relisted on the NASDAQ Global Select Market on January 21, 2021 trading under the symbol “XOG.”
Our common stock is currently listed for quotation on the NASDAQ Global Select Market. We are required to meet specified requirements to maintain our listing on the NASDAQ Global Select Market, including, among other things, a minimum bid price of $1.00 per share. If we fail to satisfy the NASDAQ Global Select Market’s continued listing requirements, we may be delisted and the quotation of our common stock may be transferred to the OTC Bulletin Board. Having our common stock quoted on the OTC Bulletin Board could adversely affect the liquidity of our common stock. Any such transfer could make it more difficult to dispose of, or obtain accurate quotations for the price of, our common stock.
Yorktown’s funds collectively holdstock, and there also would likely be a substantial portion ofreduction in our coverage by securities analysts and the voting power of our common stock.
Yorktown’s funds currently collectively hold approximately 29% of our common stock. See “Security Ownership of Certain Beneficial Owners and Management” for more information regarding ownership of our common stock bynews media, which could cause the Yorktown funds. The existence of affiliated stockholders with significant aggregate holdings that may act as a group may have the effect

of deterring hostile takeovers, delaying or preventing changes in control or changes in management, or limiting the ability of our other stockholders to approve transactions that they may deem to be in the best interests of our company. Moreover, this concentration of stock ownership may adversely affect the trading price of our common stock to the extent investors perceivedecline further. We may also face other material adverse consequences in such event, such as negative publicity, a disadvantage in owning stock of a company with affiliated stockholders with significant aggregate holdings that may act as a group.
Conflicts of interest could arise in the future between us, on the one hand, and Yorktown and its affiliates, including its funds and their respective portfolio companies, on the other hand, concerning among other things, potential competitive business activities or business opportunities.
Yorktown’s funds are in the business of making investments in entities in the U.S. energy industry. As a result, Yorktown’s funds may, from timedecreased ability to time, acquire interests in businesses that directly or indirectly compete with our business, as well as businesses that are significant existing or potential customers. Yorktown’s funds and their respective portfolio companies may acquire or seek to acquire assets that we seek to acquire and, as a result, those acquisition opportunities may not be available to us or may be more expensive for us to pursue. Under our certificate of incorporation, Yorktown’s fundsobtain additional financing, diminished investor and/or one or moreemployee confidence, and the loss of their respective affiliates are permitted to engage in business activities or invest in or acquire businessesdevelopment opportunities, any of which may compete withcontribute to a further decline in our business or do business with any client of ours. Any actual or perceived conflicts of interest with respect to the foregoing could have an adverse impact on the trading price of our common stock.stock price.
Our amended and restated certificate of incorporation and bylaws, as well as Delaware law, contain provisions that could discourage acquisition bids or merger proposals, which may adversely affect the market price of our common stock.
Our certificate of incorporation authorizes our board of directors to issue preferred stock without stockholder approval. If our board of directors elects to issue preferred stock, in addition to the Series A Preferred Stock, it could be more difficult for a third party to acquire us. In addition, some provisions of our certificate of incorporation and bylaws could make it more difficult for a third party to acquire control of us, even if the change of control would be beneficial to our stockholders, including:
limitations on the removal of directors;
limitations on the ability of our stockholders to call special meetings;
establishing advance notice provisions for stockholder proposals and nominations for elections to the board of directors to be acted upon at meetings of stockholders; and
providing that the board of directors is expressly authorized to adopt, or to alter or repeal our bylaws.
We do notWhen conditions are right and certain requirement have been met, we intend to paybegin paying dividends on our common stock, and ourstock. Our debt arrangements and the Series A Preferred Stock place certain restrictions on our ability to do so. Consequently, it is possible that the only opportunity to achieve a return on an investment in our common stock will be if the price of our common stock appreciates.
We do not plan to declare dividends on shares of our common stock in the foreseeable future. Additionally,future if certain requirements are met as stated in the RBL Credit Agreement. However, our debt arrangements and the Series A Preferred Stock restrict our ability to pay cash dividends.dividends when certain requirements have not been met. Consequently, it is possible that the only opportunity to achieve a return on an investment in our common stock will be if shareholders sell their common stock at a price greater than they paid for it. There is no guarantee that the price of our common stock that will prevail in the market will ever exceed the price that such investors paid for our common stock. There is no guarantee we will ever pay dividends.
Future sales of our common stock could reduce our stock price, and any additional capital raised by us through the sale of equity or convertible securities may dilute the ownership in us by current shareholders.
We may sell additional shares of common stock in public or private offerings. We may also issue additional shares of common stock or convertible securities. Excluding any shares of common stock issued upon the conversion of our Series A Preferred Stock including any shares of Series A Preferred Stock that may be issued pursuant to our option to pay dividends on the Series A Preferred Stock in kind pursuant to the terms of the Certificate of Designations setting forth the terms of the Series A Preferred Stock, weWe have 172,059,81425.7 million outstanding shares of common stock as of December 31, 2017. In connection with the IPO, we filed a registration statement with the SEC on Form S-8 providing for the registration of 23,000,000 shares of our common stock issued or reserved for issuance under our equity incentive plan.March 15, 2021. Subject to the satisfaction of vesting conditions, the expiration of lock-up agreements and the requirements of Rule 144, shares registered under the registration statement on Form S-8 will be available for resale immediately in the public market without restriction. Additionally, the Series A Preferred Stock are convertible into shares of our common stock pursuant to their terms.

We cannot predict the size of future issuances of our common stock or securities convertible into common stock or the effect, if any, that future issuances and sales of shares of our common stock will have on the market price of our common stock. Sales of substantial amounts of our common stock (including shares issued in connection with an acquisition), or the perception that such sales could occur, may adversely affect prevailing market prices of our common stock.

The market price of our securities is subject to volatility.
Upon our emergence from the Chapter 11 Cases, our Predecessor Common Stock was exchanged for New Common Stock (as defined in Note 1 — Business and Organization in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report). The market price of our New Common Stock could be subject to wide fluctuations in response to, and the level of trading that develops with our New Common Stock may issue additional preferredbe affected by, numerous factors, many of which are beyond our control. These factors include, among other things, our new capital structure as a result of the transactions contemplated by the Plan, our limited trading history subsequent to our emergence from bankruptcy, our limited trading volume, the lack of comparable historical financial information due to our adoption of fresh-start accounting, actual or anticipated variations in our operating results and cash flow, the nature and content of our earnings releases, announcements or events that impact our products, customers, competitors or markets, business conditions in our markets and the general state of the securities markets and the market for energy-related stocks, as well as general economic and market conditions and other factors that may affect our future results, including those described in this Part I, Item 1A. — Risk Factors section of this Annual Report.

If securities or industry analysts do not publish research or reports about our business, if they adversely change their recommendations regarding our common stock or if our operating results do not meet their expectations, our stock price could decline.
The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. Moreover, if one or more of the analysts who cover our company downgrades our common stock or if our operating results do not meet their expectations, our stock price could decline.
Our certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.
Our certificate of incorporation provides that unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim for a breach of a fiduciary duty owed by any of our directors, officers, employees or agents to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation or our bylaws, or (iv) any action asserting a claim against us that is governed by the internal affairs doctrine, in each such case subject to such Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of, and consented to, the provisions of our certificate of incorporation described in the preceding sentence. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and such persons. Alternatively, if a court were to find these provisions of our certificate of incorporation inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition or results of operations.

Risks Related to Taxes
Recent changes in United States federal income tax law may have an adverse effect on our cash flows, results of operations or financial condition overall.
On March 27, 2020, the U.S. Congress enacted into U.S. federal law the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), which, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. In particular, under the CARES Act, (i) NOLs arising in 2018, 2019, and 2020 taxable years may be carried back to each of the preceding five years and offset 100% of taxable income for tax years beginning before 2021, and (ii) for taxable years beginning in 2019 and 2020, the base for interest deductibility is increased. Future regulatory guidance may be forthcoming, and such guidance could ultimately increase or lessen this legislation’s impact on our business and financial condition. It is also possible that Congress will enact additional legislation in connection with COVID-19, some of which could have an impact on the Company.

Certain United States federal income tax deductions currently available with respect to natural gas and oil exploration and development may be eliminated as a result of future legislation.
In past years, legislation has been proposed that would, if enacted into law, make significant changes to U.S. tax laws, including to certain key U.S. federal income tax provisions currently available to oil and gas companies. Future adverse changes could include, but are not limited to, (i) the repeal of the percentage depletion allowance for oil and gas properties, (ii) the elimination of current deductions for intangible drilling and development costs, and (iii) an extension of the amortization period for certain geological and geophysical expenditures. Congress could consider, and could include, some or all of these proposals as part of future tax reform legislation. The passage of any legislation as a result of these proposals or any similar changes in U.S. federal income tax laws could eliminate or postpone certain tax deductions that currently are available with respect to oil and gas development, or increase costs, and any such changes could have an adverse effect on our financial position, results of operations and cash flows.
Our ability to use our NOL carryforwards and other tax attributes may be limited.
Under U.S. federal income tax law, a corporation is generally permitted to deduct from taxable income NOLs carried forward from prior years. We had U.S. federal NOLs of approximately $1.3 billion as of December 31, 2020. However, we expect that we will be required to substantially reduce or eliminate certain of our tax attributes, including NOL carryforwards, as a result of cancellation of indebtedness income realized in connection with the Chapter 11 Cases. Additionally, the consummation of the Plan on the Emergence Date resulted in an “ownership change,” under Section 382 of the Code. Absent an applicable exception, if a corporation undergoes an “ownership change,” the amount of its pre-ownership change net operating losses that may be utilized to offset future taxable income generally will be subject to an annual limitation equal to the value of its stock immediately prior to the ownership change multiplied by the long-term tax-exempt rate, plus an additional amount calculated based on certain “built in gains” in its assets that may be deemed to be realized within a 5-year period following any ownership change. This limitation, in the case of the ownership change that occurred as a result of the consummation of the Plan, will be subject to additional rules under Sections 382(l)(5) or (l)(6) of the Code, depending upon whether we are eligible for the application of Section 382(l)(5) of the Code and, if so eligible, whether we affirmatively elect not to apply Section 382(l)(5) of the Code. As a result of such limitation, our ability to utilize any NOLs or other tax attributes that are not eliminated as a result of cancellation of indebtedness income arising from the consummation of the Plan may be materially limited in the future.

Risks Related to Technology

We may not be able to keep pace with technological developments in our industry.
The oil and natural gas industry is characterized by rapid and significant technological advancements and introductions of new products and services using new technologies. As others use or develop new technologies, we may be placed at a competitive disadvantage or may be forced by competitive pressures to implement those new technologies at substantial costs. In addition, other oil and natural gas companies may have greater financial, technical and personnel resources that allow them to enjoy technological advantages and that may in the future allow them to implement new technologies before we can. We may not be able to respond to these competitive pressures or implement new technologies on a timely basis or at an acceptable cost. If one or more of the technologies we use now or in the future were to become obsolete, our business, financial condition or results of operations could be materially and adversely affected.
45

Our business could be negatively affected by security threats, including cybersecurity threats, destructive forms of protest and opposition by activists and other disruptions.
As an oil and natural gas producer, we face various security threats, including cybersecurity threats to gain unauthorized access to sensitive information, to misappropriate financial assets or to render data or systems unusable; threats to the security of our facilities and infrastructure or third party facilities and infrastructure, such as processing plants and pipelines; and threats from terrorist acts. The potential for such security threats has subjected our operations to increased risks that could have a material adverse effect on our business. In particular, our implementation of various procedures and controls to monitor and mitigate security threats and to increase security for our information, facilities and infrastructure may result in increased capital and operating costs. Moreover, there can be no assurance that such procedures and controls will be sufficient to prevent security breaches from occurring. If any of these security breaches were to occur, they could lead to losses of financial assets, sensitive information, critical infrastructure or capabilities essential to our operations and could have a material adverse effect on our reputation, financial position, results of operations or cash flows. Cybersecurity attacks in particular are becoming more sophisticated and include, but are not limited to, malicious software, attempts to gain unauthorized access to data and systems, and other electronic security breaches that could lead to disruptions in critical systems, unauthorized release of confidential or otherwise protected information, and corruption of data. These events could lead to financial losses from remedial actions, loss of business or potential liability. In addition, destructive forms of protest and opposition by activists and other disruptions, including acts of sabotage or eco-terrorism, against oil and gas production and activities could potentially result in damage or injury to people, property or the environment or lead to extended interruptions of our operations, adversely affecting our financial condition and results of operations.
Loss of our information and computer systems could adversely affect our business.
We are dependent on our information systems and computer-based programs, including our well operations information, seismic data, electronic data processing and accounting data. If any of such programs or systems were to fail or create erroneous information in our hardware or software network infrastructure, possible consequences include our loss of communication links, inability to find, produce, process and sell oil and natural gas and inability to automatically process commercial transactions or engage in similar automated or computerized business activities. Any such consequence could have a material adverse effect on our business.

Conservation measures and technological advances could reduce demand for oil, natural gas and NGL.

Fuel conservation measures, alternative fuel requirements, increasing consumer demand for alternatives to oil, natural gas and NGL, technological advances in fuel economy and energy generation devices could reduce demand for oil, natural gas and NGL. The impact of the changing demand for oil and gas services and products may have a material adverse effect on our business, financial condition, results of operations and cash flows.


Risks Related to the General Business

The loss of senior management or technical personnel could adversely affect operations.

We depend on the services of our senior management and technical personnel. We do not maintain, nor do we plan to obtain, any insurance against the loss of any of these individuals. The loss of the services of our senior management or technical personnel could have a material adverse effect on our business, financial condition and results of operations.
We are susceptible to the potential difficulties associated with rapid growth and expansion and have a limited operating history.
We have grown rapidly since we began operations in late 2012. Our management believes that our future success depends on our ability to manage the rapid growth that we have experienced and the demands from increased responsibility on management personnel. The following factors could present difficulties:
increased responsibilities for our executive level personnel;
increased administrative burden;
increased capital requirements; and
increased organizational challenges common to large, expansive operations.
Our operating results could be adversely affected if we do not successfully manage these potential difficulties. The historical financial information incorporated herein is not necessarily indicative of the results that may be realized in the
46

future. In addition, our operating history is limited and the results from our current producing wells are not necessarily indicative of success from our future drilling operations.
Properties we acquire may not produce as projected, and we may be unable to determine reserve potential, identify liabilities associated with the properties that we acquire or obtain protection from sellers against such liabilities.
Acquiring oil and natural gas properties requires us to assess reservoir and infrastructure characteristics, including recoverable reserves, development and operating costs and potential liabilities, including environmental liabilities. Such assessments are inexact and inherently uncertain. For these reasons, the properties we have acquired or will acquire in the future may not produce as projected. In connection with the assessments, we perform a review of the subject properties, but such a review will not reveal all existing or potential problems. In the course of our due diligence, we may not review every well, pipeline or associated facility. We cannot necessarily observe structural and environmental problems, such as pipe corrosion or groundwater contamination, when a review is performed. We may be unable to obtain contractual indemnities from the seller for liabilities created prior to our purchase of the property. We may be required to assume the risk of the physical condition of the properties in addition to the risk that the properties may not perform in accordance with our expectations.
We may be unable to make accretive acquisitions or successfully integrate acquired businesses or assets, and any inability to do so may disrupt our business and hinder our ability to grow.
In the future we may make acquisitions of oil and gas properties or businesses that complement or expand our current business. The successful acquisition of oil and gas properties requires an assessment of several factors, including:
recoverable reserves;
future oil, natural gas and NGL prices and their applicable differentials;
operating costs; and
potential environmental and other liabilities.
The accuracy of these assessments is inherently uncertain and we may not be able to identify accretive acquisition opportunities. In connection with these assessments, we perform a review of the subject properties that we believe to be generally consistent with industry practices. Our review will not reveal all existing or potential problems nor will it permit us to become sufficiently familiar with the properties to assess fully their deficiencies and capabilities. Reviews may not always be performed on every well, and environmental problems, such as groundwater contamination, are not necessarily observable even when a review is performed. Even when problems are identified, the seller may be unwilling or unable to provide effective contractual protection against all or part of the problems. We often are not entitled to contractual indemnification for environmental liabilities and acquire properties on an “as is” basis. Even if we do identify accretive acquisition opportunities, we may not be able to complete the acquisition or do so on commercially acceptable terms.
The success of any completed acquisition will depend on our ability to integrate effectively the acquired business into our existing operations. The process of integrating acquired businesses may involve unforeseen difficulties and may require a disproportionate amount of our managerial and financial resources. In addition, possible future acquisitions may be larger and for purchase prices significantly higher than those paid for earlier acquisitions. No assurance can be given that we will be able to identify additional suitable acquisition opportunities, negotiate acceptable terms, obtain financing for acquisitions on acceptable terms or successfully acquire identified targets. Our failure to achieve consolidation savings, to integrate the acquired businesses and assets into our existing operations successfully or to minimize any unforeseen operational difficulties could have a material adverse effect on our financial condition and results of operations.
In addition, our debt arrangements will impose certain limitations on our ability to enter into mergers or combination transactions. Our debt arrangements will also limit our ability to incur certain indebtedness, which could indirectly limit our ability to engage in acquisitions.
We may be subject to risks in connection with divestitures
In 2020, we announced our ongoing initiative to divest of non-strategic assets in order to increase capital resources available for other core assets, create organizational and operational efficiencies or for other purposes and completed divestitures of several of our non-strategic assets and we have additional divestitures pending, as discussed in “Business and Properties —Recent Developments.” Various factors could materially affect our ability to dispose of such assets, including the approvals of governmental agencies or third parties and the availability of purchases willing to acquire the assets with terms we deem acceptable. Though we continue to evaluate various options for the divestiture of such assets, there can be no assurance that this evaluation will result in any specific further action.
47

Sellers often retain certain liabilities or agree to indemnify buyers for certain matters related to the sold assets. The magnitude of any such retained liability or of the indemnification obligation is difficult to quantify at the time of the transaction and ultimately could be material. Also, as is typical in divestiture transactions, third parties may be unwilling to release us from guarantees or other credit support provided prior to the sale of the divested assets. As a result, after a divestiture, we may remain secondarily liable for the obligations guaranteed or supported to the extent that the buyer of the assets fails to perform these obligations.
Our cash flow from operations and access to capital are subject to a number of variables, including:
our proved reserves;
the level of hydrocarbons we are able to produce from existing wells;
the prices at which our production is sold;
the availability of takeaway capacity;
our ability to acquire, locate and produce new reserves; and
our ability to borrow under our RBL Credit Facility.
If our revenues or the borrowing base under our RBL Credit Facility decreases as a result of lower oil, natural gas and NGL prices, operating difficulties, declines in reserves or for any other reason, we may have limited ability to obtain the capital necessary to sustain our operations and growth at current levels. If additional capital is needed, we may not be able to obtain debt or equity financing on terms acceptable to us, if at all. If cash flow generated by our operations or available borrowings under our RBL Credit Facility are not sufficient to meet our capital requirements, the failure to obtain additional financing could result in a curtailment of our operations relating to development of our properties, which in turn could lead to a decline in our reserves and production, and would adversely affect our business, financial condition and results of operations.
Strategic determinations, including the allocation of capital and other resources to strategic opportunities, are challenging, and a failure to appropriately allocate capital and resources among our strategic opportunities may adversely affect our business, financial condition, results of operations or cash flows.
Our future growth prospects are dependent upon our ability to identify optimal strategies for investing our capital resources to produce rates of return. In developing our business plan, we consider allocating capital and other resources to various aspects of our business including well development (primarily drilling), reserve acquisitions, exploratory activity, corporate items and other alternatives. We also consider our likely sources of capital, including cash generated from operations and borrowings under our credit agreement. Notwithstanding the determinations made in the development of our business plan, business opportunities not previously identified periodically come to our attention, including possible acquisitions and dispositions. If we fail to identify optimal business strategies, or fail to optimize our capital investment and capital raising opportunities and the use of our other resources in furtherance of our business strategies, our financial condition and future growth may be adversely affected. Moreover, economic or other circumstances may change from those contemplated by our business plan and our failure to recognize or respond to those changes may limit our ability to achieve our objectives.
Our derivative activities could result in financial losses or could reduce our earnings.
To achieve more predictable cash flows and reduce our exposure to adverse fluctuations in the prices of oil, natural gas and NGL, we enter into commodity derivative contracts for a significant portion of our production, primarily consisting of swaps, put options and call options. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Overview—Sources of Our Revenues” in Part II, Item 7. of this Annual Report. Accordingly, our earnings may fluctuate significantly as a result of changes in fair value of our derivative instruments.
Derivative instruments also expose us to the risk of financial loss in some circumstances, including when:
production is less than the volume covered by the derivative instruments;
the counterparty to the derivative instrument defaults on its contractual obligations;
there is an increase in the differential between the underlying price in the derivative instrument and actual prices received; or
there are issues with regard to legal enforceability of such instruments.
The use of derivatives may, in some cases, require the posting of cash collateral with counterparties. If we enter into derivative instruments that require cash collateral and commodity prices or interest rates change in a manner adverse to us, our cash otherwise available for use in our operations would be reduced, which could limit our ability to make future capital expenditures and make payments on our indebtedness, and which could also limit the size of our borrowing base. Future collateral requirements will depend on arrangements with our counterparties, highly volatile oil, natural gas and NGL prices and
48

interest rates. In addition, derivative arrangements could limit the benefit we would receive from increases in the prices for oil, natural gas and NGL, which could also have an adverse effect on our financial condition.
Our commodity derivative contracts expose us to risk of financial loss if a counterparty fails to perform under a contract. Disruptions in the financial markets could lead to sudden decreases in a counterparty’s liquidity, which could make them unable to perform under the terms of the contract and we may not be able to realize the benefit of the contract. We are unable to predict sudden changes in a counterparty’s creditworthiness or ability to perform. Even if we do accurately predict sudden changes, our ability to negate the risk may be limited depending upon market conditions.
During periods of declining commodity prices, our derivative contract receivable positions generally increase, which increases our counterparty credit exposure. While we utilize multiple counterparties, if the creditworthiness of our counterparties deteriorates and results in their nonperformance, we could incur a significant loss with respect to our commodity derivative contracts.
Approximately 46% of our net leasehold acreage is undeveloped, and that acreage may not ultimately be developed or become commercially productive, which could cause us to lose rights under our leases as well as have a material adverse effect on our oil and natural gas reserves and future production and, therefore, our future cash flow and income.
As of December 31, 2020, approximately 46% of our net leasehold acreage was undeveloped, or acreage on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of oil and natural gas regardless of whether such acreage contains proved reserves. Unless production is established on the undeveloped acreage covered by our leases, such leases will expire. Our future oil and natural gas reserves and production and, therefore, our future cash flow and income are highly dependent on successfully developing our undeveloped leasehold acreage.
We are required to pay fees to our service providers based on minimum volumes under long-term contracts regardless of actual volume throughput.
We may enter into firm transportation, gas processing, gathering and compression service, water handling and treatment, or other agreements that require minimum volume delivery commitments. If we have insufficient production to meet the minimum volumes under these agreements or any other firm commitment agreement we may enter into, our cash flow from operations will be reduced, which may require us to reduce or delay our planned investments and capital expenditures or seek alternative means of financing, all of which may have a material adverse effect on our results or operations.

In February 2019, we entered into a long-term gas gathering and processing agreements with a third-party midstream provider. The agreement commenced on January 2020 and has a term of ten years with an annual minimum volume commitment of 13.0 Bcf in years one through ten. The agreement also includes a commitment to sell take-in-kind NGLs of 4,000 Bbl/d in year one, 7,500 Bbl/d in years two through seven with the ability to roll up to a 10% shortfall in a given month to the subsequent month. On December 23, 2020, we entered into a settlement with the counterparty and amended the agreement. As part of the settlement and amended agreement, there were no changes made to the minimum volume commitments. We may be required to pay a shortfall fee for any volume deficiencies under these commitments, calculated based on the applicable gathering and processing fees and/or, with respect to the NGL commitment, the NGL transport cost.

If we are unable to meet our commitments under the Elevation Gathering Agreements, we may incur additional costs.
If we are unable to meet our commitments under the Elevation Gathering Agreements, we may be required to incur additional costs. For example, if we fail to complete wells by the commitment deadline, we would be deemed to be in breach of the agreements and Elevation would be entitled to make a claim for damages against us and our affiliates.

We participate in oil and gas leases with third parties who may not be able to fulfill their commitments to our projects.
We own less than 100% of the working interest in the oil and gas leases on which we conduct operations, and other parties will own the remaining portion of the working interest. Financial risks are inherent in any operation where the cost of drilling, equipping, completing and operating wells is shared by more than one person. We could be held liable for joint activity obligations of other working interest owners, such as nonpayment of costs and liabilities arising from the actions of other working interest owners. In addition, declines in oil, natural gas and NGL prices may increase the likelihood that some of these working interest owners, particularly those that are smaller and less established, are not able to fulfill their joint activity obligations. A partner may be unable or unwilling to pay its share of project costs, and, in some cases, a partner may declare bankruptcy. In the event any of our project partners do not pay their share of such costs, we would likely have to pay those costs, and we may be unsuccessful in any efforts to recover these costs from our partners, which could materially adversely affect our financial position.
49

We own non-operating interests in properties developed and operated by third parties, and as a result, we are unable to control the operation and profitability of such properties.
We participate in the drilling and completion of wells with third-party operators that exercise exclusive control over such operations. As a participant, we rely on the third-party operators to successfully operate these properties pursuant to joint operating agreements and other similar contractual arrangements.
As a participant in these operations, we may not be able to maximize the value associated with these properties in the manner we believe appropriate, or at all. For example, we cannot control the success of drilling and development activities on properties operated by third parties, which depend on a number of factors under the control of a third-party operator, including such operator’s determinations with respect to, among other things, the nature and timing of drilling and operational activities, the timing and amount of capital expenditures and the selection of suitable technology. In addition, the third-party operator’s operational expertise and financial resources and its ability to gain the approval of other participants in drilling wells will impact the timing and potential success of drilling and development activities in a manner that we are unable to control. A third-party operator’s failure to adequately perform operations, breach of the applicable agreements or failure to act in ways that are favorable to us could reduce our production and revenues, negatively impact our liquidity and cause us to spend capital in excess of our current plans, and have a material adverse effect on our financial condition and results of operations.
We depend upon several significant purchasers for the sale of most of our oil and natural gas production. The loss of one or more of these purchasers could, among other factors, limit our access to suitable markets for the oil, natural gas and NGL we produce.
The availability of a ready market for any oil, natural gas and NGL we produce depends on numerous factors beyond the control of our management, including but not limited to the extent of domestic production and imports of oil, the proximity and capacity of pipelines, the availability of skilled labor, materials and equipment, the effect of state and federal regulation of oil and natural gas production and federal regulation of oil and gas sold in interstate commerce. In addition, we depend upon several significant purchasers for the sale of most of our oil and natural gas production. See “Business and Properties—Operations—Marketing and Customers.” We cannot assure you that we will continue to have ready access to suitable markets for our future oil and natural gas production.
The inability of one or more of our purchasers to meet their obligations may adversely affect our financial results.
We have exposure to credit risk through receivables from purchasers of our oil, natural gas and NGL production. Three, one and two purchasers accounted for more than 10% of our revenues in the years ended December 31, 2020, 2019 and 2018, respectively. During 2021, we no longer sell to our largest and third largest purchasers in 2020. Rather, we have increased our sales to our second largest purchaser in 2020 and began selling to a new midstream oil marketer who has replaced our largest purchaser in 2020. This concentration of purchasers may impact our overall credit risk in that these entities may be similarly affected by changes in economic conditions or commodity price fluctuations. We do not require our customers to post collateral. The inability or failure of our significant purchasers to meet their obligations to us or their insolvency or liquidation may materially adversely affect our financial condition and results of operations.
We may incur losses as a result of title defects in the properties in which we invest.
It is our practice in acquiring oil and natural gas leases or interests not to incur the expense of retaining lawyers to examine the title to the mineral interest at the time of acquisition. Rather, we rely upon the judgment of lease brokers or land men who perform the fieldwork in examining records in the appropriate governmental office before attempting to acquire a lease in a specific mineral interest. The existence of a material title deficiency can render a lease worthless and can adversely affect our results of operations and financial condition. While we do typically obtain title opinions prior to commencing drilling operations on a lease or in a unit, the failure of title may not be discovered until after a well is drilled, in which case we may lose the lease and the right to produce all or a portion of the minerals under the property.
Competition in the oil and natural gas industry and from alternative energy sources is intense, making it more difficult for us to acquire properties and market oil or natural gas.
Our ability to acquire additional prospects and to find and develop reserves in the future will depend on our ability to evaluate and select suitable properties and to consummate transactions in a highly competitive environment for acquiring properties, marketing oil and natural gas and securing trained personnel. Also, there is substantial competition for capital available for investment in the oil and natural gas industry. We may not be able to compete successfully in the future in acquiring prospective reserves, developing reserves, marketing hydrocarbons, and raising additional capital, which could have a material adverse effect on our business.
50

We also face indirect competition from alternative energy sources, including wind, solar, nuclear and electric power. The proliferation of alternative energy sources and businesses that provide such alternative energy sources may decrease the demand for oil and natural gas products. Decreased demand for our products could adversely affect our business, financial condition, results of operations or cash flows.
Climate change legislation or regulations restricting emissions of GHG could result in increased operating costs and reduced demand for the oil, natural gas and NGL that we produce.
Climate change continues to attract considerable public and scientific attention. As a result, numerous proposals have been made and could continue to be made at the international, national, regional and state levels of government to monitor and limit emissions of GHG. These efforts have included consideration of cap-and-trade programs, carbon taxes and GHG reporting and tracking programs, and regulations that directly limit GHG emissions from certain sources. Additionally, growing attention to climate change risks has resulted in increased likelihood of governmental investigations and private litigation, which could increase our costs or otherwise adversely affect our business.
At the federal level, no comprehensive climate change legislation has been implemented to date. However, the EPA has adopted rules under authority of the CAA that, among other things, establish PSD construction and Title V permit reviews for GHG emissions from certain large stationary sources that are also potential major sources of certain principal pollutant emissions, which reviews could require meeting “best available control technology” standards for those emissions. In addition, the EPA has adopted rules requiring the monitoring and annual reporting of GHG emissions from certain petroleum and natural gas system sources in the United States, including, among other things, onshore producing facilities, which include certain of our operations. Federal agencies also have begun directly regulating emissions of methane from oil and natural gas operations, with the EPA publishing NSPS Subpart OOOOa standards in June 2016 that require certain new, modified or reconstructed facilities in the oil and natural gas sector to reduce these methane gas and volatile organic compound emissions and the BLM publishing requirements in November 2016 to reduce methane emissions from venting, flaring, and leaking on public lands. Both of the EPA and BLM took steps to relax or rescind certain requirements under their respective methane rules. In September 2019, EPA published proposed amendments that would rescind the methane standards and roll back other requirements of the NSPS OOOOa standards and, in September 2018, BLM issued a rule that relaxes or rescinds requirements of its November 2016 regulations. California and New Mexico have challenged BLM’s September 2018 rule in ongoing litigation. Additionally, in December 2015, the United States joined the international community at the 21st Conference of the Parties of the United Nations Framework Convention on Climate Change in Paris, France preparing an agreement requiring member countries to review and “represent a progression” in their intended nationally determined contributions, which set GHG emission reduction goals every five years beginning in 2020. This “Paris Agreement” was signed by the United States in April 2016 and entered into force in November 2016; however, this agreement does not create any binding obligations for nations to limit their GHG emissions, but rather includes pledges to voluntarily limit or reduce future emissions. In August 2017, the U.S. Department of State officially informed the United Nations of the intent of the United States to withdraw from the Paris Agreement and on November 4, 2019, the U.S. submitted formal notification of its withdrawal to the United Nations. However, during the first part of 2021, the United States, under a new presidential administration, rejoined the Paris Agreement.
The adoption and implementation of any international, federal or state legislation or regulations that require reporting of GHG or otherwise limit emissions of GHG from, our equipment and operations could result in increased costs to reduce emissions of GHG associated with our operations as well as delays or restrictions in our ability to permit GHG emissions from new or modified sources. In addition, substantial limitations on GHG emissions could adversely affect demand for the oil, natural gas and NGL we produce and lower the value of our reserves, which devaluation could be significant. One or more of these developments could have a materially adverse effect on our business, financial condition and results of operations. Finally, notwithstanding potential risks related to climate change, the International Energy Agency, an autonomous intergovernmental organization involved in international energy policy, estimates that global energy demand will continue to rise and will not peak until after 2040 and oil and gas will continue to represent a substantial percentage of global energy use over that time. However, recent activism directed at shifting funding away from companies with energy-related assets could result in limitations or restrictions on certain sources of funding for the energy sector. Please read “Business and Properties—Regulation of Environmental and Safety and Health Matters—Regulation of Greenhouse Gas (“GHG”) Emissions” for a further description of the laws and regulations relating to climate change that affect us.

Adverse weather conditions may negatively affect our ability to conduct drilling activities and our operating results.

Adverse weather conditions may cause, among other things, increases in the costs of, and delays in, drilling or completing new wells, lost or damaged facilities and equipment, power failures, and temporary shut-in of production. Such extreme weather conditions could also impact other areas of our operations, including access to our drilling and production facilities for routine operations, maintenance and repairs and the availability of, and our access to, necessary third-party services,
51

such as gathering, processing, compression and transportation services. Any decreases in production due to poor weather conditions will have an adverse effect on our revenues, which will in turn negatively affect our cash flow from operations.


Risks Related to the COVID-19 Pandemic
Outbreaks of communicable diseases, including the COVID-19 pandemic, could adversely affect our business, financial condition, results of operations and cash flows.

Global or national health concerns, including the outbreak of pandemic or contagious disease, can negatively impact the global economy and, therefore, demand and pricing for oil and natural gas products. For example, there have been recent outbreaks in many countries, including the United States, of a highly transmissible and pathogenic coronavirus, which the World Health Organization declared a pandemic in March 2020. The outbreak of communicable diseases, or the perception that such an outbreak could occur, could result in a widespread public health crisis that could adversely affect the economies and financial markets of many countries, resulting in an economic downturn that would negatively impact the demand for oil and natural gas products. Furthermore, uncertainty regarding the impact and length of any outbreak of pandemic or contagious disease, including COVID-19, could lead to increased volatility in oil and natural gas prices. The occurrence or continuation of any of these events could lead to decreased revenues and limit our ability to execute on our business plan, which could adversely affect our business, financial condition, results of operations and cash flows.

Additionally, in response to the COVID-19 pandemic, our corporate staff has begun working remotely and many of our key vendors, service suppliers and partners have similarly begun to work remotely. As a result of such remote work arrangements, certain operational, reporting, accounting and other processes may slow, which could result in longer time to execute critical business functions, higher operating costs and uncertainties regarding the quality of services and supplies. Also, in the event that there is an outbreak of COVID-19 at any of our operating locations, we could be forced to cease operations at such location. Any of the foregoing could adversely affect our business, financial condition, results of operations and cash flows.

The ongoing COVID-19 pandemic and the effects of actions by, or disputes among or between, oil and natural gas producing countries may result in transportation and storage constraints, reduced production and shut-in of our wells, any of which would adversely affect our business, financial condition and results of operations.

The recent worldwide outbreak of COVID-19, the uncertainty regarding the impact of COVID-19 and various governmental actions taken to mitigate the impact of COVID-19, have resulted in an unprecedented decline in demand for oil and natural gas. At the same time, the decision by Saudi Arabia in March 2020 to drastically reduce export prices and increase oil production followed by curtailment agreements among OPEC and other countries such as Russia further increased uncertainty and volatility around global oil supply-demand dynamics. We experienced substantial decreases in our revenues beginning in the first quarter of 2020 and lasting through the end of the year, which negatively impacted our business, financial condition, results of operations, cash flows and outlook during 2020. Due to the commodity price environment, we postponed or eliminated a portion of our developmental drilling in 2020. A sustained period of weakness in oil, natural gas and NGLs prices, and the resultant effects of such prices on our drilling economics and ability to raise capital, have required us to reevaluate and further postpone or eliminate additional drilling. Such actions resulted in the reduction of our PUDs and related PV-10 and a reduction in our ability to service our debt obligations. More recently, however, reduction in oil and gas activity as a result of the COVID-19 pandemic has resulted in a decrease of production as fewer oil wells are drilled, which has led to a contraction in domestic oil and gas supply. Lower levels of supply have pushed current and forecasted oil and gas prices higher, which we expect to have a positive impact on our results of operations and cash flows. To the extent, however, that the outbreak of COVID-19 continues to negatively impact demand and we are required to further curtail our drilling program, we may be unable to continue to hold leases that are scheduled to expire, which may further reduce our reserves. As a result, if oil, natural gas and/or NGL prices remain weak, our future business, financial condition, results of operations, liquidity, and ability to finance planned capital expenditures may be materially and adversely affected.


Risks Related to Bankruptcy
We recently emerged from bankruptcy, which may adversely affect our business and relationships.
It is possible that our having filed for bankruptcy and our recent emergence from the voluntary cases under chapter 11 of the Bankruptcy Code may adversely affect our business and relationships with customers, vendors, contractors, employees or suppliers. Due to uncertainties, many risks exist, including the following:

52

key suppliers, vendors or other contract counterparties may terminate their relationships with us, require additional financial assurances or enhanced performance from us or pursue unreasonable fee increases for their goods or services;
our ability to renew existing contracts and compete for new business may be adversely affected;
our ability to attract, motivate and/or retain key employees and executives may be adversely affected;
landowners may not be willing to lease acreage to us; and
competitors may take business away from us and our ability to attract and retain customers may be negatively impacted.

The occurrence of one or more of these events could have a material and adverse effect on our operations, financial condition and reputation. We cannot assure you that having been subject to bankruptcy protection will not adversely affect our operations in the future.

Our historical financial information may not be indicative of future financial performance.

Our capital structure was significantly impacted by the Plan. Under fresh-start accounting rules that applied to us upon the Emergence Date, assets and liabilities were adjusted to fair values. Accordingly, because fresh-start accounting rules applied, our financial condition and results of operations following emergence from the Chapter 11 Cases will not be comparable to the financial condition and results of operations reflected in our historical financial statements.
Upon our emergence from the Chapter 11 Cases, the composition of our board of directors changed significantly.

Pursuant to the Plan, the composition of our board of directors changed significantly. Upon emergence, our Board consists of seven directors, none of whom served on the Board prior to our emergence from the Chapter 11 Cases. The new directors have different backgrounds, experiences and perspectives from those individuals who previously served on our Board and, thus, may have different views on the issues that will determine our future. There is no guarantee that our new Board will pursue, or will pursue in the same manner, our current strategic plans. As a result, the future strategy and our plans may differ materially from those of the past.

The ability to attract and retain key personnel is critical to the success of our business and may be affected by our emergence from the Chapter 11 Cases.

The success of our business depends on key personnel. The ability to attract and retain these key personnel may be difficult in light of our emergence from the Chapter 11 Cases, the uncertainties currently facing the business and changes we may make to the organizational structure to adjust to changing circumstances. We may need to enter into retention or other arrangements that could be costly to maintain. If executives, managers or other key personnel resign, retire or are terminated, or their service is otherwise interrupted, we may not be able to replace them in a timely manner and we could experience significant declines in productivity.

We may be negatively impacted by litigation and legal proceedings, including ongoing claims in connection with the Chapter 11 Cases.

We are subject from time to time, and in the future may become subject, to litigation claims. These claims and legal proceedings are typically claims that arise in the normal course of business and include, without limitation, claims relating to environmental, safety and health matters, commercial or contractual disputes with suppliers and customers, claims regarding ownership of mineral interests, including from royalty owners, claims regarding acquisitions and divestitures, regulatory matters and employment and labor matters. We may also become subject to governmental or regulatory proceedings. The outcome of such claims and legal proceedings cannot be predicted with certainty and some may be disposed of unfavorably to us. In addition, the claims resolutions process in connection with the Chapter 11 Cases is ongoing and certain of these claims remain subject to the jurisdiction of the Bankruptcy Court. The Bankruptcy Code provides that the confirmation of a plan of reorganization discharges a debtor from substantially all debts arising prior to confirmation. With few exceptions, all claims that arose before confirmation of the Plan (i) would be subject to compromise and/or treatment under the Plan and/or (ii) would be discharged in accordance with the terms of the Plan. Any claims not ultimately discharged through the Plan could be asserted against the reorganized entities and may have an adverse effect on their financial condition and results of operations on a post-reorganization basis. To the extent that these legal proceedings result in claims being allowed against us, such claims will be satisfied through the issuance of shares of our common stock, except as noted herein. As a result, we have not established reserves within our liabilities in connection with these claims. However, it is possible with respect to certain claims that the ultimate outcome of the legal proceedings may result in the contracts not being treated as rejected or the amounts at issue being treated as administrative claims by the Bankruptcy Court, either of which could require us to make cash payments to resolve claims instead of issuing shares of our common stock or require us to establish reserves and accrue liabilities with respect to such claims at a future date. We also may not have insurance that covers such claims and legal proceedings. Successful claims or litigation against us for significant amounts could have a material adverse effect on our reputation, business, financial condition, results of operations and cash flows. Further, even if successful in resolving a claim or legal proceeding, such process could require the attention of members of our senior management, reducing the time they have available to devote to managing our business, and require us to incur substantial legal expenses.

ITEM 1B. UNRESOLVED STAFF COMMENTS
 
We have no unresolved comments from the SEC staff regarding our periodic or current reports under the Exchange Act.Act of 1934, as amended (the “Exchange Act”).
 
ITEM 3. LEGAL PROCEEDINGS
FromWe are involved in various legal proceedings and review the status of these proceedings on an ongoing basis and, from time to time, may settle or otherwise resolve these matters on terms and conditions that management believes are in our best interests. Although the results cannot be known with certainty, we may be involved in litigation relating to claims arising out of our business and operations in the normal course of business. As of the filing date of this report, no legal proceedings are pending against us that we believe individually or collectively could have a materially adverse effect upon our financial condition, results of operations or cash flows.

We were issued a Compliance Advisory in July 2015 from the Colorado Department of Public Health and Environment (“CDPHE”), which alleged air quality violations at certain of our facilities regarding leakages of volatile organic

compounds from storage tanks, all of which were promptly addressed. On January 31, 2018, we entered into a Compliance Order on Consent with the CDPHE that provides for a field-wide administrative settlement of these issues.

The Compliance Order provides that we will implement changes to our design, operation, maintenance and recordkeeping of many of our field-wide storage tank systems to enhance our emissions management. Agreed upon and planned efforts include, but are not limited to, vapor control system modifications and verification, increased inspection and monitoring, and installation and operation of certain emission mitigation projects at certain facilities constructed in 2018 and 2019. The two primary elements of the Compliance Order are: (i) a monetary penalty of $138,600; and (ii) injunctive relief with an estimated cost of approximately $500,000, primarily representing capital enhancements to our operations. Certain expenditures for the injunctive relief have already been incurred prior to entry of the Compliance Order, with the remainder expected to be incurred over the next few years. We do notcurrently believe that the expenditures resulting from the settlementultimate results of such proceedings will not have a material adverse effect on our business, financial position, results of operations or liquidity.

COGCC Notices of Alleged Violations (“NOAVs”). We have received NOAVs from the COGCC for alleged compliance violations that we have responded to. We do not believe penalties that could result from these NOAVs will have a material effect on our business, financial condition, results of operations or liquidity, but Extraction is in negotiations to settle all of its outstanding NOAVs with the COGCC, and the ultimate settlement amount is expected to exceed $600,000.

The information set forth in Note 16 — Commitments and Contingencies — Litigation and Legal Items, to the accompanying consolidated financial statements.statements included in this Annual Report on Form 10-K is incorporated by reference into this Item 3.

OVERVIEW
 
We are an independent oil and gas company focused on the acquisition, development and production of oil, natural gas and NGL reservesreserve in the Rocky Mountain region, primarily in the Wattenberg Field of the DJ Basin.Denver-Julesburg Basin (the “DJ Basin”) of Colorado. We have developed an oil, natural gas and NGL asset base of proved reserves, as well as a portfolio of development drilling opportunities on high resource-potential leasehold on contiguous acreage blocks in some of the most productive areas of what we consider to be the core of the DJ Basin. We are focused on growing our proved reserves

Our Properties and production primarily through the development of our large inventory of identified liquids-rich horizontal drilling locations.Operations
 
Our Properties
We have assembled, as of December 31, 2017,2020, approximately 171,400140,000 net acres of large, contiguous acreage blocks in some of the most productive areas of what we consider to be the core of the DJ Basin as indicated by the results of our horizontal drilling program and the results of offset operators. Additionally, we hold approximately 183,30096,700 net acres outside of what we consider our Core DJ Basin, which we refer to as our “Other Rockies Area,” that we believe is prospective forhas many of the same formations as our properties in the Core DJ Basin. We operated 94%99% of our horizontal production for the year ended December 31, 2017,2020, our total estimated proved reserves were approximately 292.7145.9 MMBoe, of which approximately 35%77% were classified as proved developed reserves.

Financial Overview


For the year ended December 31, 2017,2020, we had a net loss of $44.4 million$1.3 billion as compared to a net loss of $456.0 million$1.4 billion for the year ended December 31, 2016.2019. The decrease in net loss was primarily driven by an increase in production revenue of $326.2 million and a decrease in non-cash compensation expense primarily relatedoperating expenses of $1.1 billion, which includes a decrease of $1.1 billion in the impairment of long-lived assets, and a change from a loss to the IPO in 2016a gain on commodity derivatives of $134.7 million, partially$202.1 million. These were offset by an increasea decrease in depletion, depreciation, amortizationsales revenues of $348.7 million, $676.9 million in reorganization items which did not exist in 2019, and accretiona $73.1 million loss on deconsolidation of Elevation Midstream, LLC which also did not exist in 2019. Additionally, interest expense of $109.7 million, associated with an increase in production volumes.decreased $22.1 million.


For the year ended December 31, 2017,2020, crude oil, natural gas, and NGL sales and gathering and compression revenue, coupled with the impact of settled derivatives, increaseddecreased to $585.7$650.7 million as compared to $306.7$881.9 million in the same prior year period due to an increase in sales volumesa decrease of 7,954 MBoe and an increase of $2.96$7.24 in realized price per BOE, including settled derivatives.derivatives, offset by an increase in sales volumes

of approximately 155 MBoe. During June 2020, we unwound the majority of our hedges when we filed for bankruptcy and received aggregate settlement proceeds of $96.1 million.
 
Adjusted EBITDAX was $380.5$449.2 million for the year ended December 31, 2017,2020, as compared to $192.3$610.7 million in the same period in 2016,2019, reflecting a 98% increase.26% decrease. Adjusted EBITDAX is a non-GAAP financial measure. For a definition of Adjusted EBITDAX and a reconciliation to our most directly comparable financial measure calculated and presented in accordance with GAAP, please read “Adjusted EBITDAX.”


Operational Overview


During the year ended December 31, 2017,2020, we continued to focusfocused on growing production while at the same time implementingemerging from bankruptcy, improving free cash flow and implemented operational efficiencies to reduce drilling, completion and completionoperating costs. We incurred approximately $864.5$159.6 million excluding outstanding elections, in drilling 18637 gross (137.4(25.7 net) wells with an average lateral length of 1.72.3 miles and completing 19845 gross (158.9(34.1 net) wells with an average lateral length of 1.72.4 miles, all of which were horizontal wells in the DJ Basin. In addition, we incurred approximately $73.2$16.9 million of leasehold and surface acreage additions, excluding acquisitions,additions.

How We Evaluate Our Operations
We use various financial and approximately $10.9 millionoperational metrics to assess the performance of midstream additions, excludingour oil and gas operations, including:
Sources of revenue;
Sales volumes;
Realized prices on the sale of oil, natural gas and NGL, including the effect of our commodity derivative contracts;
Lease operating expenses (“LOE”);
Capital expenditures;
Adjusted EBITDAX (a Non-GAAP measure); and
Free cash flow (a Non-GAAP measure).
Sources of Revenues
Our revenues are derived from the sale of our oil and natural gas production, as well as the sale of NGL that are extracted from our natural gas during processing. Our oil, natural gas and NGL revenues do not include the effects of derivatives. For the year ended December 31, 2020, our revenues were derived 69% from oil sales, 17% from natural gas sales and 14% from NGL sales. For the year ended December 31, 2019, our revenues were derived 80% from oil sales, 12% from natural gas sales and 8% from NGL sales. Our revenues may vary significantly from period to period as a result of changes in volumes of production sold or changes in commodity prices.

Sales Volumes
The following table presents historical sales volumes for the periods indicated:

Total (MBoe)32,540 32,385 
Average net sales (BOE/d)88,907 88,728 
As reservoir pressures decline, production from a given well or formation decreases. Growth in our future production and reserves will depend on our ability to continue to add or develop proved reserves in excess of our production. Accordingly, we plan to maintain our focus on adding reserves through organic growth as well as acquisitions. Our 2018ability to add reserves through development projects and acquisitions is dependent on many factors, including takeaway capacity in our areas of operation and our ability to raise capital, budget anticipatesobtain regulatory approvals, procure contract drilling rigs and personnel and successfully identify and consummate acquisitions.  Please read Item 1A. Risk Factors — Risks Related to the Oil, Natural Gas and NGL Industry and Our Business in Part 1 of this Annual Report for a two to three operated rig drilling program. further description of the risks that affect us.

Realized Prices on the Sale of Oil, Natural Gas and NGL
 
Recent AcquisitionsOur results of operations depend upon many factors, particularly the price of oil, natural gas and Divestitures

Asset Divestitures

To date, we have received multiple agreementsNGL and our ability to divest various propertiesmarket our production effectively. Oil, natural gas and NGL prices are among the most volatile of all commodity prices. For example, during the period from January 1, 2014 to December 31, 2020, NYMEX West Texas Intermediate oil prices ranged from a high of $107.26 per Bbl to a low of negative $37.63 per Bbl. Average daily prices for approximately $70.0 million.NYMEX Henry Hub gas ranged from a high of $6.15 per MMBtu to a low of $1.48 per MMBtu during the same period. Declines in, and continued depression of, the price of oil and natural gas occurring during 2015, 2019 and 2020 are due to a combination of factors including increased U.S. supply, global economic concerns stemming from COVID-19 and the price war between Russia and Saudi Arabia. These sales are not expected toprice variations can have a material impact on our financial results and capital expenditures.
Oil pricing is predominantly driven by the physical market, supply and demand, financial markets and national and international politics. The NYMEX WTI futures price is a widely used benchmark in the pricing of domestic and imported oil in the United States. The actual prices realized from the sale of oil differ from the quoted NYMEX WTI price as a result of quality and location differentials. In the DJ Basin, oil is sold under various purchase contracts with monthly pricing provisions based on NYMEX pricing, adjusted for differentials.
Natural gas prices vary by region and locality, depending upon the distance to our previously announced 2018 guidancemarkets, availability of pipeline capacity and are projected to close during the second quartersupply and demand relationships in that region or locality. The NYMEX Henry Hub price of 2018.

November 2017 Acquisition

On November 15, 2017, we acquired an unaffiliated oil andnatural gas company's interest in approximately 36,600 net acres of leasehold and primarily non-producing properties located in Arapahoe County, Colorado, (the "November 2017 Acquisition"). Upon closing the seller received $214.3 million in cash, subject to customary purchase price adjustments. We also recordedis a liability of $12.2 millionwidely used benchmark for the final settlement payment duepricing of natural gas in April 2018the United States. Similar to oil, the actual prices realized from the sale of natural gas differ from the quoted NYMEX Henry Hub price as a result of quality and location differentials. For example, wet natural gas with a high Btu content sells at a premium to low Btu content dry natural gas because it yields a greater quantity of NGL. Location differentials to NYMEX Henry Hub prices result from variances in conjunction withtransportation costs based on the November 2017 Acquisitionnatural gas’ proximity to the major consuming markets to which it is ultimately delivered. Also affecting the differential is the processing fee deduction retained by the natural gas processing plant, generally in the form of percentage of proceeds. The price we receive for total consideration of $226.5 million. The acquisition provides new development opportunitiesour natural gas produced in the DJ Basin.

July 2017 AcquisitionBasin is based on CIG prices, adjusted for certain deductions.
 
On July 7, 2017, we acquired an unaffiliatedOur price for NGL produced in the DJ Basin is based on a combination of prices from the Conway hub in Kansas and Mont Belvieu in Texas where this production is marketed.

Derivative Arrangements
 
AmendmentsTo achieve more predictable cash flow and to Revolvingreduce our exposure to adverse fluctuations in commodity prices, from time to time, we enter into derivative arrangements for our oil and natural gas production. By removing a significant portion of price volatility associated with our oil and natural gas production, we believe we will mitigate, but not eliminate, the potential negative effects of reductions in oil and natural gas prices on our cash flow from operations for those periods. However, in a portion of our current positions, our hedging activity may also reduce our ability to benefit from increases in oil and natural gas prices. We will sustain losses to the extent our derivatives contract prices are lower than market prices and, conversely, we will realize gains to the extent our derivatives contract prices are higher than market prices. In certain circumstances we may choose to restructure existing derivative contracts or enter into new transactions to modify the terms of current contracts.
We will continue to use commodity derivative instruments to hedge our price risk in the future. Our hedging strategy and future hedging transactions will be determined at our discretion and may be different than what we have done on a historical basis. We have relied on a variety of hedging strategies and instruments to hedge our future price risk. We have utilized swaps, put options and call options, which in some instances require the payment of a premium, to reduce the effect of price changes on a portion of our future oil and natural gas production. We expect to continue to use a variety of hedging strategies and instruments for the foreseeable future.
59

The hedge prices will depend on the commodity price environment at the time those hedge transactions are entered into. Our ability to enter into derivative arrangements at favorable prices may be limited, and, under our RBL Credit Agreement (as defined in Note 8Long-Term Debt in Part II, Item 8. Financial Information and Supplementary Data of this Annual Report), we are obligated to hedge a specific portion of our oil or natural gas production. The RBL Credit Agreement requires us to maintain commodity hedges covering a minimum of 65% of our anticipated oil and gas production from PDP reserves for the succeeding twelve months and 50% of our anticipated oil and gas production from PDP reserves for the next succeeding twelve months.

Lease Operating Expenses
All direct and allocated indirect costs of lifting hydrocarbons from a producing formation to the surface constitutes part of the current operating expenses of a working interest. Such costs include labor, supplies, repairs, maintenance, water injection and disposal costs, allocated overhead charges, workover, insurance and other expenses incidental to production, but exclude lease acquisition or drilling or completion expenses.
Capital Expenditures

For the year ended December 31, 2020, we incurred approximately $159.6 million in drilling and completion capital expenditures. For the year ended December 31, 2020, we drilled 37 gross (25.7 net) wells with an average lateral length of approximately 2.3 miles and completed 45 gross (34.1 net) wells with an average lateral length of approximately 2.4 miles. We turned to sales 49 gross (36.5 net) wells with an average lateral length of approximately 2.4 miles. In addition, we incurred approximately $16.9 million of leasehold and surface acreage additions.

Our 2021 capital budget for the drilling and completion of operated and non-operated wells is approximately $140 million to $180 million, substantially all of which we intend to allocate to the Core DJ Basin. We expect to drill 34 gross operated wells, complete 49 gross operated wells and turn-in-line 44 gross operated wells. Our 2021 capital budget anticipates a one-rig drilling program we expect to operate most of the year.
The amount and timing of these capital expenditures is within our control and subject to our management’s discretion. We retain the flexibility to defer or accelerate a portion of these planned capital expenditures depending on a variety of factors, including but not limited to the success of our drilling activities, prevailing and anticipated prices for oil, natural gas and NGL, the availability of necessary equipment, infrastructure and capital, the receipt and timing of required regulatory permits and approvals, seasonal conditions, drilling and acquisition costs and the level of participation by other interest owners. Any postponement or elimination of our development drilling program could result in a reduction of proved reserve volumes and related standardized measure. These risks could materially affect our business, financial condition and results of operations.

Adjusted EBITDAX
Adjusted EBITDAX is not a measure of net income (loss) as determined by GAAP. Adjusted EBITDAX is a supplemental non-GAAP financial measure that is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. We define Adjusted EBITDAX as net loss adjusted for certain cash and non-cash items, including depletion, depreciation, amortization and accretion (DD&A), impairment of long lived assets, non-recurring charges in other operating expenses, exploration and abandonment expenses, (gain) loss on sale of property and equipment, commodity derivatives (gain) loss, settlements on commodity derivative instruments, premiums paid for derivatives that settled during the period, stock-based compensation expense, amortization of debt issuance costs, interest expense, gain on repurchase of senior notes, income tax benefit, loss on deconsolidation of Elevation Midstream, LLC and reorganization items, net. Adjusted EBITDAX is also used to evaluate the performance of reportable segments. See Note 18 — Segment Information in Part II, Item 8 of this Annual Report for more information regarding the EBITDAX of reportable segments.
Management believes Adjusted EBITDAX is useful because it allows us to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to our financing methods or capital structure. We exclude the items listed above from net income (loss) in arriving at Adjusted EBITDAX because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDAX should not be considered as an alternative to, or more meaningful than, net income (loss) as determined in accordance with GAAP or as an indicator of our operating performance. Certain items excluded from Adjusted EBITDAX are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital, hedging strategy and tax structure, as well as the historic costs of depreciable assets, none of which are components of Adjusted EBITDAX. Our computations of Adjusted EBITDAX may not be comparable to other similarly titled measure of other companies. We believe that Adjusted EBITDAX is a widely followed measure of operating performance. Additionally, our management team believes Adjusted EBITDAX is useful to an investor in evaluating our financial performance because this measure (i) is widely used by investors in the oil and natural gas industry to measure a company’s operating performance without regard to items excluded from the calculation of such term, among other factors; (ii) helps investors to more meaningfully evaluate and compare the results of our operations from period to period by removing the effect of our capital structure from our operating structure; and (iii) is used by our management team for various purposes, including as a measure of operating performance, in presentations to our board of directors, as a basis for strategic planning and forecasting.

Free Cash Flow

Our Free Cash Flow is not a measure of net income (loss) as determined by GAAP. We define Free Cash Flow as Discretionary Cash Flow (non-GAAP) less Adjusted Cash Flow used in Investing (non-GAAP) adjusted for Other Non-Recurring Adjustments (non-GAAP). Discretionary Cash Flow is defined as net cash provided by operating activities (GAAP) less changes in working capital (current assets and liabilities). Adjusted Cash Flow used in Investing is defined as cash flow used in investing activities (GAAP) adjusted for changes in accounts payable and accrued liabilities related to capital expenditures.

Free Cash Flow is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. We believe Free Cash Flow can provide additional transparency into the drivers of trends in our operating cash flows, such as production, realized sales prices and operating costs, as it disregards the timing of settlement of operating assets and liabilities. We believe Free Cash Flow provides additional information that may be useful in an analysis of our ability to generate cash to fund exploration and development activities, construct and support midstream assets, and to return capital to stockholders.

The following tables present a reconciliation of Discretionary Cash Flow and Free Cash Flow to the GAAP financial measure of net cash provided by operating activities for each of the periods indicated.

Items Affecting the Comparability of Our Financial Results
Our historical results of operations for the periods presented may not be comparable, either to each other or to our future results of operations, for the reasons described below: 

During the Chapter 11 Cases, our financial results have been volatile as restructuring activities and expenses, contract terminations and rejections and claims assessments significantly impacted our financial results. For the year ended December 31, 2020, we incurred $676.9 million of reorganization items net as compared to none in 2019. As a result, our historical financial performance is likely not indicative of financial performance after the date of the bankruptcy filing. The Company emerged from the Chapter 11 proceedings on January 20, 2021, however claim assessments will continue for months longer.

Elevation Midstream, LLC was deconsolidated as of March 16, 2020 and accounted for as an equity method investment. We elected the fair value option to remeasure the Elevation Midstream, LLC equity method investment and determined it had no fair value. We recorded a $73.1 million loss on deconsolidation of Elevation Midstream, LLC in the consolidated statements of operations for the year ended December 31, 2020. Please see Note 1 — Business and Organization — Deconsolidation of Elevation Midstream, LLC in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report for information related to the deconsolidation of Elevation Midstream, LLC.

For the years ended December 31, 2020 and 2019 we recognized $194.3 million and $1.3 billion, respectively, in impairment expense on our oil and gas properties related to assets in our Core DJ Basin field and to a much lesser extent in our northern field.

For the years ended December 31, 2020 and 2019, respectively, exploration and abandonment expenses increased primarily due to the abandonment of $253.1 million and $73.7 million of unproved properties.

Year Ended December 31, 2020 Compared to Year Ended December 31, 2019
Oil sales revenues. Crude oil sales revenues decreased by $338.9 million to $382.5 million for the year ended December 31, 2020 as compared to crude oil sales of $721.4 million for the year ended December 31, 2019. A decrease in sales volumes between these periods contributed to a $135.2 million negative impact, and a decrease in crude oil prices contributed a $203.7 million negative impact. Additionally, for the year ended December 31, 2020 crude oil revenue decreased by approximately $12.3 million as compared to a crude oil revenue decrease of approximately $24.7 million for the year ended December 31, 2019 due to a contract term impacting the amount of consideration that can be included in the transaction price which reduced oil sales revenue pursuant to ASC 606.
For the year ended December 31, 2020, our crude oil sales averaged 34.3 MBbl/d. Our crude oil sales volumes decreased 19% to 12,543 MBbl for the year ended December 31, 2020 compared to 15,436 MBbl for the year ended December 31, 2019. The volume decrease was primarily due to the natural decline of our existing producing properties, which was partially offset by an increase in production from the completion of 45 wells during the year ended December 31, 2020.
The average price we realized on the sale of crude oil was $30.50 per Bbl for the year ended December 31, 2020 compared to $46.74 per Bbl for the year ended December 31, 2019, primarily due to changes in market prices for crude oil and the $12.3 million and $24.7 million decrease of crude oil revenue explained above.
Natural gas sales revenues.  Natural gas sales revenues decreased by $12.2 million to $96.7 million for the year ended December 31, 2020 as compared to natural gas sales revenues of $108.9 million for the year ended December 31, 2019. An increase in sales volumes between these periods contributed a $12.8 million positive impact, while a decrease in natural gas prices contributed a $25.0 million negative impact.
For the year ended December 31, 2020, our natural gas sales averaged 197.6 MMcf/d. Natural gas sales volumes increased by 12% to 72,311 MMcf for the year ended December 31, 2020 as compared to 64,710 MMcf for the year ended December 31, 2019. The volume increase was primarily due to the completion of 45 gross wells for the year ended December 31, 2020. The increased production from these new wells was partially offset by the natural decline of our existing producing properties.
The average price we realized on the sale of our natural gas was $1.34 per Mcf for the year ended December 31, 2020 compared to $1.68 per Mcf for the year ended December 31, 2019, primarily due to capacity constraints in transporting the wet gas associated with crude oil production coupled with a negative commodity price environment due to oversupply and a decrease in demand.
NGL sales revenues.  NGL sales revenues increased by $2.1 million to $77.2 million for the year ended December 31, 2020 as compared to NGL sales revenues of $75.1 million for the year ended December 31, 2019. An increase in sales volumes between these periods contributed a $21.6 million positive impact, while a decrease in price contributed a $19.4 million negative impact.
For the year ended December 31, 2020, our NGL sales averaged 21.7 MBbl/d. NGL sales volumes increased by 29% to 7,945 MBbl for the year ended December 31, 2020 as compared to 6,164 MBbl for the year ended December 31, 2019. The volume increase is primarily due to the completion of 45 gross wells for the year ended December 31, 2020. The increased production from these new wells was partially offset by the natural decline of our existing producing properties. Our NGL sales are directly associated with our natural gas sales because our natural gas volumes are processed by third parties for both residue natural gas sales and NGL sales.
The average price we realized on the sale of our NGL was $9.72 per Bbl for the year ended December 31, 2020 compared to $12.18 per Bbl for the year ended December 31, 2019, primarily due to capacity constraints in transporting the wet gas associated with crude oil production coupled with a negative commodity price environment due to oversupply and a decrease in demand.
Lease operating expenses ("LOE").  Our LOE, decreased by $19.5 million to $77.8 million for the year ended December 31, 2020, from $97.3 million for the year ended December 31, 2019. The decrease in LOE was primarily the result of optimization of our field cost structure during the year ended December 31, 2020. On a per unit basis, LOE decreased to $2.39 per BOE sold for the year ended December 31, 2020 from $3.00 per BOE sold for the year ended December 31, 2019.

66

Transportation and gathering. Our T&G expense increased by $85.5 million to $138.6 million for the year ended December 31, 2020, from $53.1 million for the year ended December 31, 2019. The increase in T&G is primarily attributable to an increase of volumes on a certain gathering system and a change in oil contracts.

On a per unit basis, T&G increased to $4.26 per BOE sold for the year ended December 31, 2020 from $1.64 per BOE sold for the year ended December 31, 2019.
Production taxes.  Our production taxes decreased by $39.2 million to $29.0 million for the year ended December 31, 2020 as compared to $68.2 million for the year ended December 31, 2019. The decrease was attributable to decreased revenue as production taxes are calculated as a percentage of sales revenue. Production taxes as a percentage of sales revenue was 5.2% for the year ended December 31, 2020 as compared to 7.5% for the year ended December 31, 2019. The decrease in production taxes as a percentage of sales revenue relates to a decrease in the estimated ad valorem and severance tax rates and an adjustment to the estimated ad valorem tax payable as of December 31, 2020.
Exploration and abandonment expenses.  Our exploration and abandonment expenses were $258.9 million and $88.8 million for the years ended December 31, 2020 and 2019, respectively. We recognized $4.9 million in expense attributable to the extension of certain leases and $253.1 million in expense attributable to the abandonment of unproved properties for the year ended December 31, 2020. We recognized $12.4 million in expense attributable to the extension of certain leases and $73.7 million in expense attributable to the abandonment of unproved properties for the year ended December 31, 2019.
Depletion, depreciation, amortization and accretion expense.  Our DD&A expense decreased $192.2 million to $332.3 million for the year ended December 31, 2020 as compared to $524.5 million for the year ended December 31, 2019. This decrease was due to an impairment of $1.3 billion of proved oil and gas properties that occurred during the fourth quarter of 2019. On a per unit basis, DD&A expense decreased from $16.20 per BOE for the year ended December 31, 2019 to $10.21 per BOE for the year ended December 31, 2020.
Impairment of long lived assets.  For the year ended December 31, 2020, our impairment expense was $208.5 million, related to the impairment of other property and equipment, well equipment inventory, and the impairment of oil and gas properties in our Core DJ Basin field as the field’s fair values did not exceed the carrying amounts associated with our proved oil and gas properties. For the year ended December 31, 2019, our impairment expense was $1.3 billion. We recognized $14.5 million related to impairment of the proved oil and gas properties in our northern field and $1.3 billion of impairment expense was recognized for the year ended December 31, 2019 on proved oil and gas properties in our Core DJ Basin field.
(Gain) loss on sale of property and equipment and assets of unconsolidated subsidiary.  Our gain on the sale of insignificant property was $0.1 million for the year ended December 31, 2020, as compared to a $0.4 million loss for the year ended December 31, 2019, which was related to our March 2019 Divestiture, August 2019 Divestiture and December 2019 Divestitures.
General and administrative expenses (“G&A”).  General and administrative expenses decreased by $43.6 million to $55.2 million for the year ended December 31, 2020 as compared to $98.8 million for the year ended December 31, 2019. This decrease was primarily due to a decrease of $37.6 million in stock based compensation and a decrease in employed workforce of 61%, or 198 employees during the year ended December 31, 2020 compared to the year ended December 31, 2019. On a per unit basis, G&A expenses decreased by $1.35 per BOE from $3.05 per BOE sold for the year ended December 31, 2019 to $1.70 per BOE sold for the year ended December 31, 2020.
Our G&A expenses include the non-cash expense for stock-based compensation for equity awards granted to our employees and directors. For the year ended December 31, 2020, stock-based compensation expense was $6.4 million as compared to stock-based compensation expense of $44.0 million for the year ended December 31, 2019. On a per unit basis, stock-based compensation decreased $1.16 per BOE from $1.36 per BOE sold for the year ended December 31, 2019 to $0.20 per BOE sold for the year ended December 31, 2020.

Other operating expenses. Other operating expenses were $79.6 million for the year ended December 31, 2020. This amount is made up of a $46.8 million loss contingency related to an alleged breach in contract, $4.2 million of accrued interest related to the aforementioned breach in contract, a $13.2 million early termination fee related to the termination of our crude oil marketing contract, $7.6 million incurred due to workforce reductions, $4.1 million incurred in production tax interest expense, a $2.4 million early termination fee related to the termination of a drilling rig contract, and $1.3 million in expenses related to legal accruals and other.
67

Commodity derivative gain (loss).  Primarily due to the unwinding of trades due to the commencement of the Chapter 11 Cases, coupled with the decrease in NYMEX crude oil futures prices at December 31, 2020 as compared to December 31, 2019 and change in fair value from the execution of new positions, we incurred a net gain on our commodity derivatives of $165.0 million for the year ended December 31, 2020. Primarily due to the increase in NYMEX crude oil futures prices at December 31, 2019 as compared to December 31, 2018 and change in fair value from the execution of new positions, we incurred a net loss on our commodity derivatives of $37.1 million. These gains and losses are a result of our hedging program, which is used to mitigate our exposure to commodity price fluctuations. The fair value of the open commodity derivative instruments will continue to change in value until the transactions are settled and we will likely add to our hedging program in the future. Therefore, we expect our net income (loss) to reflect the volatility of commodity price forward markets. Our cash flow will only be affected upon settlement of the transactions at the current market prices at that time. For the years ended December 31, 2020 and 2019, we received and paid cash settlements of commodity derivatives totaling $188.8 million and $5.8 million, respectively.

Loss on deconsolidation of Elevation Midstream, LLC. On March 16, 2020, we deconsolidated Elevation Midstream, LLC. Upon deconsolidation, we elected the fair value option to remeasure the Elevation equity method investment and determined it had no fair value. The Company recorded a $73.1 million loss on deconsolidation of Elevation Midstream, LLC in the consolidated statements of operations for the year ended December 31, 2020.

Reorganization items, net. Due to the commencement of the Chapter 11 Cases during the second quarter of 2020, we have incurred and will continue to incur significant costs associated with our reorganization, primarily from damages for rejected or settled contracts and legal and professional fees. For the year ended December 31, 2020, we recognized $676.9 million in reorganization items. No reorganization items were recognized during the same period in the preceding year. Please see Note 6 — Reorganization Items, Net in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report.
Interest expense.  Interest expense consists of interest expense on our long-term debt and debt issuance costs, net of capitalized interest. For the year ended December 31, 2020, we recognized interest expense of approximately $57.1 million as compared to $79.2 million for the year ended December 31, 2019, as a result of borrowings under our Prior Credit Facility, our DIP Credit Facility, our 2024 Senior Notes, our 2026 Senior Notes, and the amortization of other debt issuance costs.
We incurred interest expense for the year ended December 31, 2020 of approximately $58.8 million related to our 2024 Senior Notes, 2026 Senior Notes, Prior Credit Facility and Capital Raise

2026DIP Credit Facility. We incurred interest expense for the year ended December 31, 2019 of approximately $91.5 million related to our 2024 Senior Notes,
On January 25, 2018, we issued at par $750.0 million principal amount of 5.625% Senior Notes due February 1, 2026 (the "2026 Senior Notes" and the offering, the "2026 Senior Notes Offering"). The 2026 Senior Notes bearand Prior Credit Facility. Also included in interest expense for the years ended December 31, 2020 and 2019 was the amortization of debt issuance costs of $3.7 million and $5.5 million, respectively, and a gain on the sale of extinguishment of debt of $10.5 million for the year ended December 31, 2019. For the years ended December 31, 2020 and 2019, we capitalized interest expense of $5.3 million and $7.2 million, respectively.

Income tax (expense) benefit.  We recorded no income tax expense (benefit) for the year ended December 31, 2020 resulting in an annual interesteffective tax rate of 5.625%approximately zero. We recorded an income tax benefit of approximately $109.2 million for the year ended December 31, 2019 resulting in an effective tax rate of approximately 7.4%. Our effective tax rate for 2020 and 2019 differs from the U.S. statutory income tax rate of 21% primarily due to the effects of state income taxes, estimated permanent taxable differences, nondeductible stock-based compensation, and the recording of a valuation allowance against deferred tax assets.

Gathering and facilities segment. Prior to March 31, 2020, we had two operating segments, (i) the exploration, development and production of oil, natural gas and NGL (the “exploration and production segment”) and (ii) the construction, operation and support of midstream assets to gather and process crude oil and gas production (the “gathering and facilities segment”). Please see Note 1 — Business and Organization — Deconsolidation of Elevation Midstream, LLC in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report for further information related to the deconsolidation of Elevation Midstream, LLC. After March 31, 2020, Extraction began reporting as a single reportable segment.

Our consolidated statements of operations for the year ended December 31, 2020 contains the following amounts, which were incurred during the first quarter of 2020. The interestgathering and facilities segment had revenues of $6.0 million and direct operating expenses of $3.9 million. General and administrative expenses were $0.7 million and depreciation expense was $1.1 million as the gathering facility was placed into service during the fourth quarter of 2019. Please see Note 18 — Segments in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report.

Our consolidated statements of operations for the year ended December 31, 2019 contains the following amounts. The gathering and facilities segment had revenues of $6.9 million and direct operating expenses of $2.3 million. General and administrative expenses were $4.6 million and depreciation expense was $1.4 million as the gathering facility was placed into service during the fourth quarter of 2019.

Liquidity and Capital Resources

Chapter 11 Cases and Effect of Automatic Stay

On June 14, 2020, we filed for relief under Chapter 11 of the Bankruptcy Code. The commencement of a voluntary proceeding in bankruptcy constituted an immediate event of default under the Prior Credit Agreement (defined below) and the indentures governing our Senior Notes, resulting in the automatic and immediate acceleration of all of our outstanding debt under the Prior Credit Agreement and the Senior Notes. Any efforts to enforce payment obligations related to the acceleration of our debt were automatically stayed as a result of the filing of the Chapter 11 Cases, and the creditors’ rights of enforcement are subject to the applicable provisions of the Bankruptcy Code. On June 14, 2020, we also entered into the Restructuring Support Agreement (“RSA”) with certain holders of our Senior Notes to support a restructuring in accordance with the terms set forth therein. As more fully disclosed in Note 1 — Business and Organization and Note 8 Long-Term Debt in Part II, Item 8. Financial Information and Supplementary Data of this Annual Report, the RSA contemplated a financial restructuring which would provide for the treatment of holders of certain claims and existing equity interests. The Plan, which included substantially all terms set forth in the RSA, was approved by the Bankruptcy Court on December 23, 2020 and we emerged from bankruptcy on January 20, 2020.

We continued operations in the ordinary course for the duration of the Chapter 11 Cases funding operations with our DIP Credit Facility (as defined in Note 8 Long-Term Debt in Part II, Item 8. Financial Information and Supplementary Data of this Annual Report along with all capitalized debt terms in this paragraph). Upon emergence from bankruptcy, our Prior Credit Facility and DIP Credit Facility were paid off and we obtained a RBL Credit Facility discussed below.

As a result of the Chapter 11 Cases, our total available liquidity as of December 31, 2020 consisted of cash on hand of $205.9 million and $11.5 million of availability on the DIP Credit Facility. With this liquidity and funds generated from ongoing operations, we funded cash requirements throughout 2020 during the Chapter 11 proceedings. As such, we paid and expect to continue paying vendor and royalty obligations according to the terms of our current contracts.

Sources of Liquidity and Capital Resources
Historically, our primary sources of liquidity have been borrowings under our Prior Credit Facility, proceeds from notes offerings and preferred stock offerings, equity provided by investors, including our management team, cash from issuance of preferred stock, and cash flows from divestitures and from the sale of oil, gas and NGL production. Our primary uses of capital have been for the acquisition of oil and gas properties to increase our acreage position, as well as development and exploration of oil and gas properties. As of December 31, 2020, our DIP Credit Facility borrowings were $106.7 million, with $75.0 million total outstanding including amounts that were rolled over from the Prior Credit Facility. Our Prior Credit Facility borrowings were $453.7 million and $470.0 million at December 31, 2020, and December 31, 2019, respectively. We had senior notes totaling $1.1 billion outstanding at December 31, 2020 and December 31, 2019. We also have other contractual commitments, which are described in Note 16 — Commitments and Contingencies in Part II, Item 8. Financial Information and Supplementary Data of this Annual Report.

Upon emergence from bankruptcy on January 20, 2021 indebtedness under our 2024 and 2026 Senior Notes was discharged in exchange for equity as is payableexplained in Note 1 Business and Organization in Part II, Item 8. Financial Information and Supplementary Data of this Annual Report. Our Prior Credit Facility and DIP Credit Facility were paid off, terminated and replaced by our RBL Credit Facility that has a maximum commitment of $1.0 billion with an initial borrowing base and current elected lending commitments of $500.0 million.

As of approximately $737.9the date of this filing, we have drawn $253.7 million on the RBL Credit Facility. Total funds available for borrowing under our RBL Credit Facility, after deducting discounts and fees. We used $534.2giving effect to an aggregate of $0.5 million of undrawn letters of credit, were $245.8 million as of the date of this filing.
We enter into hedging arrangements to reduce the impact of commodity price volatility on our cash flow from operations, or alternatively, we may decide to unwind or restructure the hedging arrangements we previously entered into. The RBL Credit Agreement requires us to maintain commodity hedges covering a minimum of 65% of our anticipated oil and gas production from PDP reserves for the succeeding twelve months and 50% of our anticipated oil and gas production from PDP reserves for the next succeeding twelve months.

Our 2021 capital budget for the drilling and completion of operated and non-operated wells is approximately $140 million to $180 million, substantially all of which we intend to allocate to the Core DJ Basin. We expect to drill 34 gross operated wells, complete 49 gross operated wells and turn-in-line 44 gross operated wells. Our 2021 capital budget anticipates a one-rig drilling program we expect to operate most of the year.

    We had a Stock Repurchase Program in place that ended in 2019. Spending under this program was $137.0 million and we repurchased 34.1 million shares during the year ended December 31, 2019. We also had a Senior Notes Repurchase Program in place. Spending under this program during the year ended December 31, 2019 was $39.3 million. No common stock or Senior Notes were repurchased during the year ended December 31, 2020.
Cash Flows
The following table summarizes our cash flows for the periods indicated (in thousands):

Net cash used in investing activities(245,101)(850,153)
Net cash provided by financing activities160,362 89,592 

Year Ended December 31, 2020 Compared to the Year Ended December 31, 2019
Net cash provided by operating activities. For the year ended December 31, 2020 as compared to the year ended December 31, 2019, our net proceedscash provided by operating activities decreased by $292.0 million primarily due to a decrease in operating revenues net of expenses of $377.3 million as a result of a decrease in commodity prices and a decrease of $126.3 million related to changes in working capital when excluding the $582.4 million change in accrued damages for rejected and settled contracts. Also, cash paid for reorganization items during 2020 increased $34.4 million. These reductions to cash inflows were partially offset by an increase of $90.5 million in commodity derivative settlement payments, a decrease of $46.1 million in cash paid for interest and a decrease of $6.1 million in cash paid for general and administrative expenses.

Net cash used in investing activities. For the year ended December 31, 2020 as compared to the year ended December 31, 2019, our net cash used in investing activities decreased by $605.1 million primarily due to decreased spending of $385.9 million on oil and gas property additions, $206.7 million on our gathering systems and facilities, $35.4 million on other property and equipment, and $20.0 million on investments in an unconsolidated subsidiary. During 2020, cash received from the 2026 Senior Notes Offering to tender for our 2021 Senior Notes, $52.7sale of property and equipment decreased $41.9 million to redeem any 2021 Senior Notes not tendered and cash received from the remainder will be used for general corporate purposes. Our borrowing base under our revolving credit facility was automatically reduced to $700.0 million in connection withsale of assets of unconsolidated subsidiary decreased $1.0 million.

Net cash provided by financing activities. For the closing of the 2026 Senior Notes Offering; however, there was no changeyear ended December 31, 2020 as compared to the current maximum lending commitments of $650.0year ended December 31, 2019, our net cash provided by financing activities increased by $70.8 million.
Tender Offer to Purchase 2021 Senior Notes

On January 25, 2018, we announced Net borrowings on the results of our cash tender offer to purchase any and all of the outstanding aggregate principal amount of the 2021 Senior Notes. An aggregate principal amount of $500.6 million (91%) was tendered and paid, in addition to a make-whole premium of $32.6Prior Credit Facility decreased $54.5 million, and accrued and unpaid interestno cash was received in 2020 from the issuance of $1.0Elevation Preferred Units compared to $99.0 million received during 2019. These decreases were offset by an increase in net borrowings on January 25, 2018. On February 17, 2018, we redeemed the approximately $49.4 million aggregate principal amount of the 2021 Senior Notes that remained outstanding after the Tender Offer and made a cash payment of approximately $52.7 million to the remaining holders of the 2021 Senior Notes, which includes a make-whole premium of $3.0 million and accrued and unpaid interest of approximately $0.3 million.


January 2018DIP Credit Facility Amendment

On January 5, 2018, we amended the revolving credit facility to (i) increase the borrowing base from $525.0of $31.7 million, to $750.0a decrease in cash spent on payroll withholding taxes of $1.7 million, subject to the current maximum lending commitments of $650.0 million, (ii) increase the maximum amount for the letter of credit issueda decrease in favor of a purchaser of our crude oil be increased from $25.0 million to $35.0 million, and (iii) amend certain provisions of the credit agreement, including the commitments and allocations of each lender. Subsequent to this amendment our borrowing base was reduced in connections with the 2026 Senior Notes Offering. See "–Liquidity and Capital Resources–Revolving Credit Facility.”

October 2017 Credit Facility Amendment

On October 11, 2017, we amended the revolving credit facility to, among other things, (i) provide for the joinder of new lenders, (ii) increase the borrowing base under the credit facility from $375.0 million to $525.0 million, and (iii) amend certain provisions of the credit agreement, including the commitments and allocations of each lender. See “–Liquidity and Capital Resources–Revolving Credit Facility.”

August 2017 Credit Facility Amendment and Restatement
On August 16, 2017, we entered into an amendment and restatement of our existing credit facility, which provides commitments of $1.5 billion with a syndicate of banks, which was subject to a borrowing base of $375.0 million. The credit facility matures on the earlier of (a) August 16, 2022, (b) January 15, 2021 if (and only if) our 2021 Senior Notes (as defined below) have not been refinanced or repaid in full on or prior to January 15, 2021, (c) April 15, 2021, if (and only if) (i) the convertible preferred equity interests issued by us has not been converted into common equity or redeemed prior to April 15, 2021, and (ii) prior to April 15, 2021, the maturity date of the Series A Preferred Stock has not been extendeddividends of $10.9 million, and a decrease of Preferred Unit Issuance costs of $2.5 million during 2020 compared to 2019. Additionally, during 2020 no cash was spent repurchasing common stock and senior notes, but during 2019 cash spent to repurchase common stock was $137.7 million, as result of our Share Repurchase Program, and senior notes was $39.3 million, as a date that is no earlier than six months after August 16, 2022 or (d) the earlier termination in wholeresult of the commitments.

2024 Senior NotesWorking Capital
 
On August 1, 2017, we issuedOur working capital deficit at par $400.0December 31, 2020 was $369.4 million principaland at December 31, 2019 was $240.8 million. However, as of December 31, 2020, many of our current liabilities in the amount of 7.375% Senior Notes due May 15, 2024 (the "2024 Senior Notes"$279.6 million were classified as liabilities subject to compromise (excluding approximately $1.8 billion of debt, accrued interest, damages for rejected and settled contracts and other). Our cash balances totaled $205.9 million and $32.4 million at December 31, 2020 and 2019, respectively.

Due to the amounts that we incur related to our drilling and completion program and the offering,timing of such expenditures, we may incur working capital deficits in the "2024 Senior Notes Offering"). Thefuture. We expect that our cash flows from operating activities and availability under our RBL Credit Facility will be sufficient to fund our working capital needs. We expect that our pace of development, production volumes, commodity prices and differentials to NYMEX prices for our oil, natural gas and NGL production will be the largest variables affecting our working capital.

Commitments, Contingencies and Contractual Obligations

The information responsive to Item 303 (a)(5) of Regulation S-K is not required of smaller reporting companies.
Off-Balance Sheet Arrangements
As of December 31, 2020, we do not have material off-balance sheet arrangements.
Impact of Inflation/Deflation and Pricing
All of our transactions are denominated in U.S. dollars. Typically, as prices for oil and natural gas increase, associated costs rise. Conversely, as prices for oil and natural gas decrease, costs decline. Cost declines tend to lag and may not adjust downward in proportion to decline commodity prices. Historically, field-level prices received for our oil and natural gas production have been volatile. During the year ended December 31, 2020, commodity prices decreased during the first and second quarters and subsequently increased in the third and fourth quarters. During the year ended December 31, 2019, commodity prices decreased during the first quarter, increased in the second quarter, and subsequently decreased in the third quarter and fourth quarter. Changes in commodity prices impact our revenues, estimates of reserves, assessments of any impairment of oil and natural gas properties, as well as values of properties being acquired or sold. Price changes have the potential to affect our ability to raise capital, borrow money, and retain personnel.

Critical Accounting Policies and Estimates
Use of Estimates in the Preparation of Financial Statements
The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of oil and gas reserves, assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant areas requiring the use of assumptions, judgments and estimates include:

(1) oil and gas reserves;
(2) depreciation, depletion, amortization and accretion;
(3) cash flow estimates used in impairment testing of oil and gas proved and unproved properties;
(4) valuation of commodity derivative instruments;
(5) assigning fair value and allocating purchase price in connection with business combinations, including the determination of any resulting goodwill;
(6) asset retirement obligations;
(7) accrued revenue and related receivables;
(8) valuation of stock-based payments,
(9) income taxes, and
(10) bankruptcy proceedings.

Although management believes these estimates are reasonable, actual results could differ from these estimates. We evaluate our estimates on an annualon-going basis and base our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances. Although actual results may differ from these estimates under different assumptions or conditions, we believe our estimates are reasonable.
71

Successful Efforts Method of Accounting
We follow the successful efforts method of accounting for oil and gas properties. Under this method of accounting, all property acquisition costs and development costs are capitalized when incurred and depleted on a units-of-production basis over the remaining life of proved reserves and proved developed reserves, respectively.
The costs of exploratory wells are initially capitalized pending a determination of whether proved reserves have been found. At the completion of drilling activities, the costs of exploratory wells remain capitalized if a determination is made that proved reserves have been found. If no proved reserves have been found, the costs of exploratory wells are charged to expense. In some cases, a determination of proved reserves cannot be made at the completion of drilling, requiring additional testing and evaluation of the wells. Cost incurred for exploratory wells that find reserves that cannot yet be classified as proved are capitalized if (a) the well has found a sufficient quantity of reserves to justify its completion as a producing well and (b) sufficient progress in assessing the reserves and the economic and operating viability of the project has been made. The status of suspended well costs is monitored continuously and reviewed quarterly. Due to the capital-intensive nature and the geographical characteristics of certain projects, it may take an extended period of time to evaluate the future potential of an exploration project and the economics associated with making a determination of its commercial viability.
Geological and geophysical costs are expensed as incurred. Costs of seismic studies that are utilized in development drilling within an area of proved reserves are capitalized as development costs. Amounts of seismic costs capitalized are based on only those blocks of data used in determining development well locations. To the extent that a seismic project covers areas of both developmental and exploratory drilling, those seismic costs are proportionately allocated between development costs and exploration expense.
We capitalize interest, rateif debt is outstanding, during drilling operations in our exploration and development activities.
Oil and Gas Reserves
Our estimates of 7.375%. The interestproved reserves are based on the 2024 Senior Notesquantities of oil, natural gas and NGL, 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 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 that renewal is payablereasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. Our independent petroleum engineers, Ryder Scott, prepare a reserve and economic evaluation of all of our properties on May 15a well-by-well basis. The accuracy of reserve estimates is a function of the: 

quality and November 15quantity of available data;
interpretation of that data;
accuracy of various mandated economic assumptions; and
judgment of the independent reserve engineer.
One of the most significant estimates we make is the estimate of oil, natural gas and NGL reserves. Oil, natural gas and NGL reserve estimates require significant judgments in the evaluation of all available geological, geophysical, engineering and economic data. The data for a given field may change substantially over time as a result of numerous factors including, but not limited to, additional development activity, production history, projected future production, economic assumptions relating to commodity prices, operating expenses, severance and other taxes, capital expenditures and remediation costs and these estimates are inherently uncertain. For example, if estimates of proved reserves decline, our DD&A rate will increase, resulting in a decrease in net income. A decline in estimates of proved reserves could also cause us to perform an impairment analysis to determine if the carrying amount of oil and gas properties exceeds fair value and could result in an impairment charge, which would reduce earnings. We cannot predict what reserve revisions may be required in future periods.
Ryder Scott estimated all of our proved reserve quantities as of December 31, 2020 and 2019. In connection with Ryder Scott performing their independent reserve estimations, we furnish them with the following information that they review: (1) technical support data, (2) technical analysis of geologic and engineering support information, (3) economic and production data and (4) our well ownership interests.
The following table presents information about proved reserve changes from period to period due to items we do not control, such as price, and from changes due to production history and well performance. These changes do not require a capital expenditure on our part, but may have resulted from capital expenditures we incurred to develop other estimated proved reserves. 
72

 For the Year Ended December 31,
 20202019
Revisions resulting from price changes (MBOE)(27,204)(18,049)
Revisions resulting from production, performance and other (MBOE)(60,105)(72,488)
Total revisions (MBOE)(87,309)(90,537)
Declines in oil, natural gas and NGL prices increase the uncertainty as to the impact of commodity prices on our estimated proved reserves. We are unable to predict future commodity prices with any greater precision than the futures market. A prolonged period of depressed commodity prices may have a significant impact on the value and volumetric quantities of our proved reserve portfolio, assuming no other changes to our development plans or costs.
Depreciation, Depletion, Amortization and Accretion
Our DD&A rate is dependent upon our estimates of total proved and proved developed reserves, which incorporate various assumptions and future projections. If our estimates of total proved or proved developed reserves decline, the rate at which we record DD&A expense increases, which in turn reduces our net income. Such a decline in reserves may result from lower commodity prices or other changes to reserve estimates, as discussed above, and we are unable to predict changes in reserve quantity estimates as such quantities are dependent on the success of our exploration and development program, as well as future economic conditions.
Impairment of Proved Oil and Gas Properties
Proved oil and gas properties are reviewed for impairment annually or when events and circumstances indicate a possible decline in the recoverability of the carrying amount of such property. We estimate the expected future cash flows of our oil and gas properties and compares these undiscounted cash flows to the carrying amount of the oil and gas properties to determine if the carrying amount is recoverable. If the carrying amount exceeds the estimated undiscounted future cash flows, we will write down the carrying amount of the oil and gas properties to fair value. The factors used to determine fair value include, but are not limited to, estimates of reserves, future commodity prices, future production estimates, estimated future capital expenditures, estimated future operating costs, and discount rates commensurate with the risk associated with realizing the projected cash flows. Impairment expense for proved oil and gas properties is reported in impairment of long lived assets and goodwill in the consolidated statements of operations, which increases accumulated depletion, depreciation and amortization.
Future commodity pricing for oil is based on five-year West Texas Intermediate strip prices, which decreased 14.0% from an average of $53.65/Bbl at December 31, 2019 to an average of $46.14/Bbl at December 31, 2020. Future commodity pricing for natural gas is based on five-year Henry Hub strip prices, which increased 4.9% from an average of $2.42/MMBtu at December 31, 2019 to an average of $2.54/MMBtu at December 31, 2020. Future commodity pricing for NGLs is based on five-year WTI strip prices, which decreased 10.7% from an average of $14.40/Bbl at December 31, 2019 to an average of $12.85/Bbl at December 31, 2020.

Our impairment analysis requires us to apply judgment in identifying impairment indicators and estimating future cash flows of our oil and gas properties. If actual results are not consistent with our assumptions and estimates or our assumptions and estimates change due to new information, we may be exposed to an impairment charge.

For the year ended December 31, 2020, our impairment expense related to oil and gas properties was $197.9 million. We recognized $3.6 million related to impairment of the proved oil and gas properties in our northern field and $194.3 million related to assets in one of our Core DJ Basin fields, as the fields’ fair values did not exceed the carrying amounts associated with our proved oil and gas properties. For the year ended December 31, 2019, our impairment expense was $1.3 billion. We recognized $14.5 million related to impairment of the proved oil and gas properties in our northern field and $1.3 billion related to assets in one of our Core DJ Basin fields as the fields’ fair values did not exceed the carrying amounts associated with our proved oil and gas properties.

Forward commodity prices and estimates of future production play a significant role in determining impairment of proved oil and gas properties. As a result of lower commodity prices and their impact on our estimated future cash flows, we will continue to review our proved oil and gas properties for impairment. After our fourth quarter 2020 impairment charges in two of our Core DJ Basin fields at December 31, 2020, the carrying value of our oil and gas properties exceeded our expected undiscounted future cash flows for proved and risk-adjusted probable and possible reserves by approximately $56.8 million and $340.3 million, in each field. After our fourth quarter 2019 impairment charges in two of our Core DJ Basin fields at
73

December 31, 2019, the carrying value of our oil and gas properties exceeded our expected undiscounted future cash flows for proved and risk-adjusted probable and possible reserves by approximately $33.8 million and $1.2 billion, in each field. At December 31, 2018, our expected undiscounted future cash flows exceeded the carrying value of our proved oil and gas properties by approximately $0.8 billion, or 30%.
Abandonment of Unproved Oil and Gas Properties
Unproved oil and gas properties consist of costs to acquire unevaluated leases as well as costs to acquire unproved reserves. We evaluate significant unproved oil and gas properties for impairment based on remaining lease term, drilling results, reservoir performance, seismic interpretation or future plans to develop acreage. When successful wells are drilled on undeveloped leaseholds, unproved property costs are reclassified to proved properties and depleted on a unit-of-production basis. Impairment expense and lease extension payments for unproved properties is reported in exploration and abandonment expenses in the consolidated statements of operations. As a result of the abandonment of unproved properties, we recognized $253.1 million and $73.7 million in abandonment expense for the years ended December 31, 2020 and 2019, respectively. To the extent we do not elect to renew current leases, we expect further abandonment charges in 2021.

Commodity Derivative Instruments
We have entered into commodity derivative instruments utilizing swaps to reduce the effect of price changes on a portion of our future oil and natural gas production. For a description of our derivative instruments that we utilize and a summary of our open commodity derivative contracts as of December 31, 2020, please see Note 9 — Commodity Derivative Instruments in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report.
The commodity derivative instruments are measured at fair value and are included in the accompanying consolidated balance sheets as commodity derivative assets or liabilities. We have not designated any of the derivative contracts as fair value or cash flow hedges. Therefore, we do not apply hedge accounting to the commodity derivative instruments. Net gains and losses on commodity derivative instruments are recorded based on the changes in the fair values of the derivative instruments. Net gains and losses on commodity derivative instruments are recorded in the commodity derivative gain (loss) line on the consolidated statements of operations. Our cash flow is only impacted when the actual settlements under the commodity derivative contracts result in making or receiving a payment to or from the counterparty. These settlements under the commodity derivative contracts are reflected as operating activities in our consolidated statements of cash flows.
Our valuation estimate takes into consideration the counterparties’ credit worthiness, our credit worthiness, and the time value of money. The consideration of the factors results in an estimated exit-price for each derivative asset or liability under a market participant’s view. We believe that this approach provides a reasonable, non-biased, verifiable, and consistent methodology for valuing commodity derivative instruments. Please see “—How We Evaluate Our Operations—Derivative Arrangements.”

Accounting for Business Combinations

We account for all of our business combinations using the acquisition method, which is the only method permitted under ASC 805, Business Combinations, and involves the use of significant judgment. In connection with a business combination, the acquiring company must allocate the cost of the acquisition to assets acquired and liabilities assumed based on fair values as of the acquisition date. Any excess or shortage of amounts assigned to assets and liabilities over or under the purchase price is recorded as a gain on bargain purchase or goodwill. The amount of goodwill or gain on bargain purchase recorded in any particular business combination can vary significantly depending upon the values attributed to assets acquired and liabilities assumed.

In estimating the fair values of assets acquired and liabilities assumed in a business combination, we make various assumptions. The most significant assumptions relate to the estimated fair values assigned to proved and unproved oil and gas properties. If sufficient market data is not available regarding the fair values of proved and unproved properties, we must prepare estimates. To estimate the fair values of these properties, we prepare estimates of gas, oil and NGL reserves. We estimate future prices to apply to the estimated reserves quantities acquired and estimate future operating and development costs to arrive at estimates of future net cash flows. For estimated proved reserves, the future net cash flows are discounted using a market-based weighted average cost of capital rate determined appropriate at the time of the acquisition. The market-based weighted average cost of capital rate is subjected to additional project-specific risking factors. To compensate for the inherent risk of estimating and valuing unproved reserves, when a discounted cash flow model is used, the discounted future net cash flows of probable and possible reserves are reduced by additional risk factors. In some instances, market comparable information of recent transactions is used to estimate fair value of unproved acreage.
74


Estimated fair values assigned to assets acquired can have a significant effect on results of operations in the future. A higher fair value assigned to a property results in higher DD&A expense, which results in lower net earnings. Fair values are based on estimates of future commodity prices, reserves quantities, operating expenses and development costs. This increases the likelihood of impairment if future commodity prices or reserves quantities are lower than those originally used to determine fair value, or if future operating expenses or development costs are higher than those originally used to determine fair value. Impairment would have no effect on cash flows but would result in a decrease in net income for the period in which the impairment is recorded.

Asset Retirement Obligations
Our asset retirement obligations (“ARO”) consist of estimated future costs associated with the plugging and abandonment of oil, natural gas and NGL wells, removal of equipment and facilities from leased acreage and land restoration in accordance with applicable local, state and federal laws, and applicable lease terms. The fair value of an ARO liability is required to be recognized in the period in which it is incurred, with the associated asset retirement cost capitalized as part of the carrying cost of the oil and gas asset. The recognition of an ARO requires that management make numerous assumptions regarding such factors as the estimated probabilities, amounts and timing of settlements; the credit-adjusted risk-free discount rate to be used; and inflation rates. In periods subsequent to the initial measurement of the ARO, we must recognize period-to-period changes in the liability resulting from the passage of time and revisions to either the timing or the amount of the original estimate of undiscounted cash flows. Increases in the ARO liability due to the passage of time impact net income as accretion expense. The related capitalized cost, including revisions thereto, is charged to expense through DD&A over the life of the oil and gas property.
Revenue Recognition
Revenue from the sale of oil, natural gas and NGLs is recognized in accordance with ASC 606 - Revenue from Contracts with Customers five-step revenue recognition model to depict the transfer of goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. To account for producer imbalances, we recognize revenues on all sales of oil, natural gas and NGLs to third party customers regardless of their ownership percentage and adjust the underlifter or overlifter’s claim on the asset’s remaining reserves. In other words, revenue is recorded based on our share of volume sold, regardless of whether we have taken our proportional share of volume produced. A receivable or liability is recognized only to the extent that we have an imbalance on a specific property greater than the expected remaining proved reserves. We receive payment one to three months after delivery. At the end of each year commencing on November 15, 2017. Wemonth, we estimate the amount of production delivered to purchasers and the price we will receive. Variances between our estimates and the actual amounts received net proceeds ofare recorded in the month payment is received. A 10% change in our revenue accrual would have impacted total operating revenues by approximately $392.6$6.3 million after deducting discounts and fees.$10.5 million for the years ended December 31, 2020 and 2019, respectively.

Stock-Based Payments
 
We granted awards under the 2016 LTIP and 2021 LTIP (as defined in Note 14 — Stock-Based Compensation in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report) to certain directors, officers and employees, including stock options, restricted stock units, performance stock awards, performance stock units, performance cash awards and cash awards which therefore required us to recognize the expense in our consolidated financial statements.

All stock-based payments to employees are measured at fair value on the grant date and expensed over the relevant service period. The fair value of stock option awards is determined by using the Black-Scholes option pricing model. The fair value of the PSAs was measured at the grant date with a stochastic process method using a Monte Carlo simulation. All stock-based payment expense is recognized using the straight-line method and is included within general and administrative expenses in the consolidated statements of operations and stock-based compensation in the consolidated statements of cash flows. Forfeitures are recorded as they occur. Please refer to Note 14 — Stock-Based Compensation in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report for additional discussion on stock-based payments.

Income TaxesCapital Expenditures

For the year ended December 31, 2020, we incurred approximately $159.6 million in drilling and completion capital expenditures. For the year ended December 31, 2020, we drilled 37 gross (25.7 net) wells with an average lateral length of approximately 2.3 miles and completed 45 gross (34.1 net) wells with an average lateral length of approximately 2.4 miles. We turned to sales 49 gross (36.5 net) wells with an average lateral length of approximately 2.4 miles. In addition, we incurred approximately $16.9 million of leasehold and surface acreage additions.

Our 2021 capital budget for the drilling and completion of operated and non-operated wells is approximately $140 million to $180 million, substantially all of which we intend to allocate to the Core DJ Basin. We expect to drill 34 gross operated wells, complete 49 gross operated wells and turn-in-line 44 gross operated wells. Our 2021 capital budget anticipates a one-rig drilling program we expect to operate most of the year.
 
On December 22, 2017,The amount and timing of these capital expenditures is within our control and subject to our management’s discretion. We retain the Tax Cuts and Jobs Act (the “TCJA”) was enacted making significant changesflexibility to defer or accelerate a portion of these planned capital expenditures depending on a variety of factors, including but not limited to the Internal Revenue Code.success of our drilling activities, prevailing and anticipated prices for oil, natural gas and NGL, the availability of necessary equipment, infrastructure and capital, the receipt and timing of required regulatory permits and approvals, seasonal conditions, drilling and acquisition costs and the level of participation by other interest owners. Any postponement or elimination of our development drilling program could result in a reduction of proved reserve volumes and related standardized measure. These risks could materially affect our business, financial condition and results of operations.

Adjusted EBITDAX
Adjusted EBITDAX is not a measure of net income (loss) as determined by GAAP. Adjusted EBITDAX is a supplemental non-GAAP financial measure that is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. We have calculated our best estimatedefine Adjusted EBITDAX as net loss adjusted for certain cash and non-cash items, including depletion, depreciation, amortization and accretion (DD&A), impairment of long lived assets, non-recurring charges in other operating expenses, exploration and abandonment expenses, (gain) loss on sale of property and equipment, commodity derivatives (gain) loss, settlements on commodity derivative instruments, premiums paid for derivatives that settled during the impactperiod, stock-based compensation expense, amortization of the TCJA in our year-enddebt issuance costs, interest expense, gain on repurchase of senior notes, income tax provisionbenefit, loss on deconsolidation of Elevation Midstream, LLC and reorganization items, net. Adjusted EBITDAX is also used to evaluate the performance of reportable segments. See Note 18 — Segment Information in Part II, Item 8 of this Annual Report for more information regarding the EBITDAX of reportable segments.
Management believes Adjusted EBITDAX is useful because it allows us to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to our financing methods or capital structure. We exclude the items listed above from net income (loss) in arriving at Adjusted EBITDAX because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDAX should not be considered as an alternative to, or more meaningful than, net income (loss) as determined in accordance with GAAP or as an indicator of our operating performance. Certain items excluded from Adjusted EBITDAX are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital, hedging strategy and tax structure, as well as the historic costs of depreciable assets, none of which are components of Adjusted EBITDAX. Our computations of Adjusted EBITDAX may not be comparable to other similarly titled measure of other companies. We believe that Adjusted EBITDAX is a widely followed measure of operating performance. Additionally, our management team believes Adjusted EBITDAX is useful to an investor in evaluating our financial performance because this measure (i) is widely used by investors in the oil and natural gas industry to measure a company’s operating performance without regard to items excluded from the calculation of such term, among other factors; (ii) helps investors to more meaningfully evaluate and compare the results of our operations from period to period by removing the effect of our capital structure from our operating structure; and (iii) is used by our management team for various purposes, including as a measure of operating performance, in presentations to our board of directors, as a basis for strategic planning and forecasting.

Free Cash Flow

Our Free Cash Flow is not a measure of net income (loss) as determined by GAAP. We define Free Cash Flow as Discretionary Cash Flow (non-GAAP) less Adjusted Cash Flow used in Investing (non-GAAP) adjusted for Other Non-Recurring Adjustments (non-GAAP). Discretionary Cash Flow is defined as net cash provided by operating activities (GAAP) less changes in working capital (current assets and guidanceliabilities). Adjusted Cash Flow used in Investing is defined as cash flow used in investing activities (GAAP) adjusted for changes in accounts payable and accrued liabilities related to capital expenditures.

Free Cash Flow is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. We believe Free Cash Flow can provide additional transparency into the drivers of trends in our operating cash flows, such as production, realized sales prices and operating costs, as it disregards the timing of settlement of operating assets and liabilities. We believe Free Cash Flow provides additional information that may be useful in an analysis of our ability to generate cash to fund exploration and development activities, construct and support midstream assets, and to return capital to stockholders.

Items Affecting the Comparability of Our Financial Results
Our historical results of operations for the periods presented may not be comparable, either to each other or to our future results of operations, for the reasons described below: 

During the Chapter 11 Cases, our financial results have been volatile as restructuring activities and expenses, contract terminations and rejections and claims assessments significantly impacted our financial results. For the year ended December 31, 2020, we incurred $676.9 million of reorganization items net as compared to none in 2019. As a result, our historical financial performance is likely not indicative of financial performance after the date of the bankruptcy filing. The Company emerged from the Chapter 11 proceedings on January 20, 2021, however claim assessments will continue for months longer.

Elevation Midstream, LLC was deconsolidated as of March 16, 2020 and accounted for as an equity method investment. We elected the fair value option to remeasure the Elevation Midstream, LLC equity method investment and determined it had no fair value. We recorded a $73.1 million loss on deconsolidation of Elevation Midstream, LLC in the consolidated statements of operations for the year ended December 31, 2020. Please see Note 1 — Business and Organization — Deconsolidation of Elevation Midstream, LLC in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report for information related to the deconsolidation of Elevation Midstream, LLC.

For the years ended December 31, 2020 and 2019 we recognized $194.3 million and $1.3 billion, respectively, in impairment expense on our oil and gas properties related to assets in our Core DJ Basin field and to a much lesser extent in our northern field.

For the years ended December 31, 2020 and 2019, respectively, exploration and abandonment expenses increased primarily due to the abandonment of $253.1 million and $73.7 million of unproved properties.

Year Ended December 31, 2020 Compared to Year Ended December 31, 2019
Oil sales revenues. Crude oil sales revenues decreased by $338.9 million to $382.5 million for the year ended December 31, 2020 as compared to crude oil sales of $721.4 million for the year ended December 31, 2019. A decrease in sales volumes between these periods contributed to a $135.2 million negative impact, and a decrease in crude oil prices contributed a $203.7 million negative impact. Additionally, for the year ended December 31, 2020 crude oil revenue decreased by approximately $12.3 million as compared to a crude oil revenue decrease of approximately $24.7 million for the year ended December 31, 2019 due to a contract term impacting the amount of consideration that can be included in the transaction price which reduced oil sales revenue pursuant to ASC 606.
For the year ended December 31, 2020, our crude oil sales averaged 34.3 MBbl/d. Our crude oil sales volumes decreased 19% to 12,543 MBbl for the year ended December 31, 2020 compared to 15,436 MBbl for the year ended December 31, 2019. The volume decrease was primarily due to the natural decline of our existing producing properties, which was partially offset by an increase in production from the completion of 45 wells during the year ended December 31, 2020.
The average price we realized on the sale of crude oil was $30.50 per Bbl for the year ended December 31, 2020 compared to $46.74 per Bbl for the year ended December 31, 2019, primarily due to changes in market prices for crude oil and the $12.3 million and $24.7 million decrease of crude oil revenue explained above.
Natural gas sales revenues.  Natural gas sales revenues decreased by $12.2 million to $96.7 million for the year ended December 31, 2020 as compared to natural gas sales revenues of $108.9 million for the year ended December 31, 2019. An increase in sales volumes between these periods contributed a $12.8 million positive impact, while a decrease in natural gas prices contributed a $25.0 million negative impact.
For the year ended December 31, 2020, our natural gas sales averaged 197.6 MMcf/d. Natural gas sales volumes increased by 12% to 72,311 MMcf for the year ended December 31, 2020 as compared to 64,710 MMcf for the year ended December 31, 2019. The volume increase was primarily due to the completion of 45 gross wells for the year ended December 31, 2020. The increased production from these new wells was partially offset by the natural decline of our existing producing properties.
The average price we realized on the sale of our natural gas was $1.34 per Mcf for the year ended December 31, 2020 compared to $1.68 per Mcf for the year ended December 31, 2019, primarily due to capacity constraints in transporting the wet gas associated with crude oil production coupled with a negative commodity price environment due to oversupply and a decrease in demand.
NGL sales revenues.  NGL sales revenues increased by $2.1 million to $77.2 million for the year ended December 31, 2020 as compared to NGL sales revenues of $75.1 million for the year ended December 31, 2019. An increase in sales volumes between these periods contributed a $21.6 million positive impact, while a decrease in price contributed a $19.4 million negative impact.
For the year ended December 31, 2020, our NGL sales averaged 21.7 MBbl/d. NGL sales volumes increased by 29% to 7,945 MBbl for the year ended December 31, 2020 as compared to 6,164 MBbl for the year ended December 31, 2019. The volume increase is primarily due to the completion of 45 gross wells for the year ended December 31, 2020. The increased production from these new wells was partially offset by the natural decline of our existing producing properties. Our NGL sales are directly associated with our natural gas sales because our natural gas volumes are processed by third parties for both residue natural gas sales and NGL sales.
The average price we realized on the sale of our NGL was $9.72 per Bbl for the year ended December 31, 2020 compared to $12.18 per Bbl for the year ended December 31, 2019, primarily due to capacity constraints in transporting the wet gas associated with crude oil production coupled with a negative commodity price environment due to oversupply and a decrease in demand.
Lease operating expenses ("LOE").  Our LOE, decreased by $19.5 million to $77.8 million for the year ended December 31, 2020, from $97.3 million for the year ended December 31, 2019. The decrease in LOE was primarily the result of optimization of our field cost structure during the year ended December 31, 2020. On a per unit basis, LOE decreased to $2.39 per BOE sold for the year ended December 31, 2020 from $3.00 per BOE sold for the year ended December 31, 2019.

66

Transportation and gathering. Our T&G expense increased by $85.5 million to $138.6 million for the year ended December 31, 2020, from $53.1 million for the year ended December 31, 2019. The increase in T&G is primarily attributable to an increase of volumes on a certain gathering system and a change in oil contracts.

On a per unit basis, T&G increased to $4.26 per BOE sold for the year ended December 31, 2020 from $1.64 per BOE sold for the year ended December 31, 2019.
Production taxes.  Our production taxes decreased by $39.2 million to $29.0 million for the year ended December 31, 2020 as compared to $68.2 million for the year ended December 31, 2019. The decrease was attributable to decreased revenue as production taxes are calculated as a percentage of sales revenue. Production taxes as a percentage of sales revenue was 5.2% for the year ended December 31, 2020 as compared to 7.5% for the year ended December 31, 2019. The decrease in production taxes as a percentage of sales revenue relates to a decrease in the estimated ad valorem and severance tax rates and an adjustment to the estimated ad valorem tax payable as of December 31, 2020.
Exploration and abandonment expenses.  Our exploration and abandonment expenses were $258.9 million and $88.8 million for the years ended December 31, 2020 and 2019, respectively. We recognized $4.9 million in expense attributable to the extension of certain leases and $253.1 million in expense attributable to the abandonment of unproved properties for the year ended December 31, 2020. We recognized $12.4 million in expense attributable to the extension of certain leases and $73.7 million in expense attributable to the abandonment of unproved properties for the year ended December 31, 2019.
Depletion, depreciation, amortization and accretion expense.  Our DD&A expense decreased $192.2 million to $332.3 million for the year ended December 31, 2020 as compared to $524.5 million for the year ended December 31, 2019. This decrease was due to an impairment of $1.3 billion of proved oil and gas properties that occurred during the fourth quarter of 2019. On a per unit basis, DD&A expense decreased from $16.20 per BOE for the year ended December 31, 2019 to $10.21 per BOE for the year ended December 31, 2020.
Impairment of long lived assets.  For the year ended December 31, 2020, our impairment expense was $208.5 million, related to the impairment of other property and equipment, well equipment inventory, and the impairment of oil and gas properties in our Core DJ Basin field as the field’s fair values did not exceed the carrying amounts associated with our proved oil and gas properties. For the year ended December 31, 2019, our impairment expense was $1.3 billion. We recognized $14.5 million related to impairment of the proved oil and gas properties in our northern field and $1.3 billion of impairment expense was recognized for the year ended December 31, 2019 on proved oil and gas properties in our Core DJ Basin field.
(Gain) loss on sale of property and equipment and assets of unconsolidated subsidiary.  Our gain on the sale of insignificant property was $0.1 million for the year ended December 31, 2020, as compared to a $0.4 million loss for the year ended December 31, 2019, which was related to our March 2019 Divestiture, August 2019 Divestiture and December 2019 Divestitures.
General and administrative expenses (“G&A”).  General and administrative expenses decreased by $43.6 million to $55.2 million for the year ended December 31, 2020 as compared to $98.8 million for the year ended December 31, 2019. This decrease was primarily due to a decrease of $37.6 million in stock based compensation and a decrease in employed workforce of 61%, or 198 employees during the year ended December 31, 2020 compared to the year ended December 31, 2019. On a per unit basis, G&A expenses decreased by $1.35 per BOE from $3.05 per BOE sold for the year ended December 31, 2019 to $1.70 per BOE sold for the year ended December 31, 2020.
Our G&A expenses include the non-cash expense for stock-based compensation for equity awards granted to our employees and directors. For the year ended December 31, 2020, stock-based compensation expense was $6.4 million as compared to stock-based compensation expense of $44.0 million for the year ended December 31, 2019. On a per unit basis, stock-based compensation decreased $1.16 per BOE from $1.36 per BOE sold for the year ended December 31, 2019 to $0.20 per BOE sold for the year ended December 31, 2020.

Other operating expenses. Other operating expenses were $79.6 million for the year ended December 31, 2020. This amount is made up of a $46.8 million loss contingency related to an alleged breach in contract, $4.2 million of accrued interest related to the aforementioned breach in contract, a $13.2 million early termination fee related to the termination of our crude oil marketing contract, $7.6 million incurred due to workforce reductions, $4.1 million incurred in production tax interest expense, a $2.4 million early termination fee related to the termination of a drilling rig contract, and $1.3 million in expenses related to legal accruals and other.
67

Commodity derivative gain (loss).  Primarily due to the unwinding of trades due to the commencement of the Chapter 11 Cases, coupled with the decrease in NYMEX crude oil futures prices at December 31, 2020 as compared to December 31, 2019 and change in fair value from the execution of new positions, we incurred a net gain on our commodity derivatives of $165.0 million for the year ended December 31, 2020. Primarily due to the increase in NYMEX crude oil futures prices at December 31, 2019 as compared to December 31, 2018 and change in fair value from the execution of new positions, we incurred a net loss on our commodity derivatives of $37.1 million. These gains and losses are a result of our hedging program, which is used to mitigate our exposure to commodity price fluctuations. The fair value of the open commodity derivative instruments will continue to change in value until the transactions are settled and we will likely add to our hedging program in the future. Therefore, we expect our net income (loss) to reflect the volatility of commodity price forward markets. Our cash flow will only be affected upon settlement of the transactions at the current market prices at that time. For the years ended December 31, 2020 and 2019, we received and paid cash settlements of commodity derivatives totaling $188.8 million and $5.8 million, respectively.

Loss on deconsolidation of Elevation Midstream, LLC. On March 16, 2020, we deconsolidated Elevation Midstream, LLC. Upon deconsolidation, we elected the fair value option to remeasure the Elevation equity method investment and determined it had no fair value. The Company recorded a $73.1 million loss on deconsolidation of Elevation Midstream, LLC in the consolidated statements of operations for the year ended December 31, 2020.

Reorganization items, net. Due to the commencement of the Chapter 11 Cases during the second quarter of 2020, we have incurred and will continue to incur significant costs associated with our reorganization, primarily from damages for rejected or settled contracts and legal and professional fees. For the year ended December 31, 2020, we recognized $676.9 million in reorganization items. No reorganization items were recognized during the same period in the preceding year. Please see Note 6 — Reorganization Items, Net in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report.
Interest expense.  Interest expense consists of interest expense on our long-term debt and debt issuance costs, net of capitalized interest. For the year ended December 31, 2020, we recognized interest expense of approximately $57.1 million as compared to $79.2 million for the year ended December 31, 2019, as a result of borrowings under our Prior Credit Facility, our DIP Credit Facility, our 2024 Senior Notes, our 2026 Senior Notes, and the amortization of other debt issuance costs.
We incurred interest expense for the year ended December 31, 2020 of approximately $58.8 million related to our 2024 Senior Notes, 2026 Senior Notes, Prior Credit Facility and DIP Credit Facility. We incurred interest expense for the year ended December 31, 2019 of approximately $91.5 million related to our 2024 Senior Notes, 2026 Senior Notes and Prior Credit Facility. Also included in interest expense for the years ended December 31, 2020 and 2019 was the amortization of debt issuance costs of $3.7 million and $5.5 million, respectively, and a gain on the sale of extinguishment of debt of $10.5 million for the year ended December 31, 2019. For the years ended December 31, 2020 and 2019, we capitalized interest expense of $5.3 million and $7.2 million, respectively.

Income tax (expense) benefit.  We recorded no income tax expense (benefit) for the year ended December 31, 2020 resulting in an effective tax rate of approximately zero. We recorded an income tax benefit of approximately $109.2 million for the year ended December 31, 2019 resulting in an effective tax rate of approximately 7.4%. Our effective tax rate for 2020 and 2019 differs from the U.S. statutory income tax rate of 21% primarily due to the effects of state income taxes, estimated permanent taxable differences, nondeductible stock-based compensation, and the recording of a valuation allowance against deferred tax assets.

Gathering and facilities segment. Prior to March 31, 2020, we had two operating segments, (i) the exploration, development and production of oil, natural gas and NGL (the “exploration and production segment”) and (ii) the construction, operation and support of midstream assets to gather and process crude oil and gas production (the “gathering and facilities segment”). Please see Note 1 — Business and Organization — Deconsolidation of Elevation Midstream, LLC in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report for further information related to the deconsolidation of Elevation Midstream, LLC. After March 31, 2020, Extraction began reporting as a single reportable segment.

Our consolidated statements of operations for the year ended December 31, 2020 contains the following amounts, which were incurred during the first quarter of 2020. The gathering and facilities segment had revenues of $6.0 million and direct operating expenses of $3.9 million. General and administrative expenses were $0.7 million and depreciation expense was $1.1 million as the gathering facility was placed into service during the fourth quarter of 2019. Please see Note 18 — Segments in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report.

Our consolidated statements of operations for the year ended December 31, 2019 contains the following amounts. The gathering and facilities segment had revenues of $6.9 million and direct operating expenses of $2.3 million. General and administrative expenses were $4.6 million and depreciation expense was $1.4 million as the gathering facility was placed into service during the fourth quarter of 2019.

Liquidity and Capital Resources

Chapter 11 Cases and Effect of Automatic Stay

On June 14, 2020, we filed for relief under Chapter 11 of the Bankruptcy Code. The commencement of a voluntary proceeding in bankruptcy constituted an immediate event of default under the Prior Credit Agreement (defined below) and the indentures governing our Senior Notes, resulting in the automatic and immediate acceleration of all of our outstanding debt under the Prior Credit Agreement and the Senior Notes. Any efforts to enforce payment obligations related to the acceleration of our debt were automatically stayed as a result of the filing of the Chapter 11 Cases, and the creditors’ rights of enforcement are subject to the applicable provisions of the Bankruptcy Code. On June 14, 2020, we also entered into the Restructuring Support Agreement (“RSA”) with certain holders of our Senior Notes to support a restructuring in accordance with the terms set forth therein. As more fully disclosed in Note 1 — Business and Organization and Note 8 Long-Term Debt in Part II, Item 8. Financial Information and Supplementary Data of this Annual Report, the RSA contemplated a financial restructuring which would provide for the treatment of holders of certain claims and existing equity interests. The Plan, which included substantially all terms set forth in the RSA, was approved by the Bankruptcy Court on December 23, 2020 and we emerged from bankruptcy on January 20, 2020.

We continued operations in the ordinary course for the duration of the Chapter 11 Cases funding operations with our DIP Credit Facility (as defined in Note 8 Long-Term Debt in Part II, Item 8. Financial Information and Supplementary Data of this Annual Report along with all capitalized debt terms in this paragraph). Upon emergence from bankruptcy, our Prior Credit Facility and DIP Credit Facility were paid off and we obtained a RBL Credit Facility discussed below.

As a result of the Chapter 11 Cases, our total available liquidity as of December 31, 2020 consisted of cash on hand of $205.9 million and $11.5 million of availability on the DIP Credit Facility. With this liquidity and funds generated from ongoing operations, we funded cash requirements throughout 2020 during the Chapter 11 proceedings. As such, we paid and expect to continue paying vendor and royalty obligations according to the terms of our current contracts.

Sources of Liquidity and Capital Resources
Historically, our primary sources of liquidity have been borrowings under our Prior Credit Facility, proceeds from notes offerings and preferred stock offerings, equity provided by investors, including our management team, cash from issuance of preferred stock, and cash flows from divestitures and from the sale of oil, gas and NGL production. Our primary uses of capital have been for the acquisition of oil and gas properties to increase our acreage position, as well as development and exploration of oil and gas properties. As of December 31, 2020, our DIP Credit Facility borrowings were $106.7 million, with $75.0 million total outstanding including amounts that were rolled over from the Prior Credit Facility. Our Prior Credit Facility borrowings were $453.7 million and $470.0 million at December 31, 2020, and December 31, 2019, respectively. We had senior notes totaling $1.1 billion outstanding at December 31, 2020 and December 31, 2019. We also have other contractual commitments, which are described in Note 16 — Commitments and Contingencies in Part II, Item 8. Financial Information and Supplementary Data of this Annual Report.

Upon emergence from bankruptcy on January 20, 2021 indebtedness under our 2024 and 2026 Senior Notes was discharged in exchange for equity as is explained in Note 1 Business and Organization in Part II, Item 8. Financial Information and Supplementary Data of this Annual Report. Our Prior Credit Facility and DIP Credit Facility were paid off, terminated and replaced by our RBL Credit Facility that has a maximum commitment of $1.0 billion with an initial borrowing base and current elected lending commitments of $500.0 million. The borrowing base will be redetermined semiannually on or around May 1 and November 1 of each year, with one interim “wildcard” redetermination available to us and our administrative agent between scheduled redeterminations during any 12-month period. The next scheduled redetermination will be on or around May 1, 2021.

As of the date of this filing, we have drawn $253.7 million on the RBL Credit Facility. Total funds available for borrowing under our RBL Credit Facility, after giving effect to an aggregate of $0.5 million of undrawn letters of credit, were $245.8 million as of the date of this filing. Many
We enter into hedging arrangements to reduce the impact of commodity price volatility on our cash flow from operations, or alternatively, we may decide to unwind or restructure the hedging arrangements we previously entered into. The RBL Credit Agreement requires us to maintain commodity hedges covering a minimum of 65% of our anticipated oil and gas production from PDP reserves for the succeeding twelve months and 50% of our anticipated oil and gas production from PDP reserves for the next succeeding twelve months.

Our 2021 capital budget for the drilling and completion of operated and non-operated wells is approximately $140 million to $180 million, substantially all of which we intend to allocate to the Core DJ Basin. We expect to drill 34 gross operated wells, complete 49 gross operated wells and turn-in-line 44 gross operated wells. Our 2021 capital budget anticipates a one-rig drilling program we expect to operate most of the provisionsyear.

    We had a Stock Repurchase Program in place that ended in 2019. Spending under this program was $137.0 million and we repurchased 34.1 million shares during the TCJA have an effective date for years beginning afteryear ended December 31, 2017, including2019. We also had a Senior Notes Repurchase Program in place. Spending under this program during the loweringyear ended December 31, 2019 was $39.3 million. No common stock or Senior Notes were repurchased during the year ended December 31, 2020.
Cash Flows
The following table summarizes our cash flows for the periods indicated (in thousands): 

 For the Year Ended December 31, 
 20202019
Net cash provided by operating activities$265,975 $557,957 
Net cash used in investing activities(245,101)(850,153)
Net cash provided by financing activities160,362 89,592 

Year Ended December 31, 2020 Compared to the Year Ended December 31, 2019
Net cash provided by operating activities. For the year ended December 31, 2020 as compared to the year ended December 31, 2019, our net cash provided by operating activities decreased by $292.0 million primarily due to a decrease in operating revenues net of the U.S. corporate rate from 35% to 21%. However,expenses of $377.3 million as a result of a decrease in commodity prices and a decrease of $126.3 million related to changes in working capital when excluding the enactment date$582.4 million change in accrued damages for rejected and settled contracts. Also, cash paid for reorganization items during 2020 increased $34.4 million. These reductions to cash inflows were partially offset by an increase of $90.5 million in commodity derivative settlement payments, a decrease of $46.1 million in cash paid for interest and a decrease of $6.1 million in cash paid for general and administrative expenses.

Net cash used in investing activities. For the year ended December 31, 2020 as compared to the year ended December 31, 2019, our net cash used in investing activities decreased by $605.1 million primarily due to decreased spending of $385.9 million on oil and gas property additions, $206.7 million on our gathering systems and facilities, $35.4 million on other property and equipment, and $20.0 million on investments in an unconsolidated subsidiary. During 2020, cash received from the sale of property and equipment decreased $41.9 million and cash received from the sale of assets of unconsolidated subsidiary decreased $1.0 million.

Net cash provided by financing activities. For the year ended December 31, 2020 as compared to the year ended December 31, 2019, our net cash provided by financing activities increased by $70.8 million. Net borrowings on the Prior Credit Facility decreased $54.5 million, and no cash was received in 2020 from the issuance of Elevation Preferred Units compared to $99.0 million received during 2019. These decreases were offset by an increase in net borrowings on the DIP Credit Facility of $31.7 million, a decrease in cash spent on payroll withholding taxes of $1.7 million, a decrease in Series A Preferred Stock dividends of $10.9 million, and a decrease of Preferred Unit Issuance costs of $2.5 million during 2020 compared to 2019. Additionally, during 2020 no cash was spent repurchasing common stock and senior notes, but during 2019 cash spent to repurchase common stock was $137.7 million, as result of our Share Repurchase Program, and senior notes was $39.3 million, as a result of our Senior Notes Repurchase Program.
Working Capital
Our working capital deficit at December 31, 2020 was $369.4 million and at December 31, 2019 was $240.8 million. However, as of December 22, 2017,31, 2020, many of our current liabilities in the amount of $279.6 million were classified as liabilities subject to compromise (excluding approximately $1.8 billion of debt, accrued interest, damages for rejected and settled contracts and other). Our cash balances totaled $205.9 million and $32.4 million at December 31, 2020 and 2019, respectively.

Due to the amounts that we incur related to our drilling and completion program and the timing of such expenditures, we may incur working capital deficits in the future. We expect that our cash flows from operating activities and availability under our RBL Credit Facility will be sufficient to fund our working capital needs. We expect that our pace of development, production volumes, commodity prices and differentials to NYMEX prices for our oil, natural gas and NGL production will be the largest variables affecting our working capital.

The information responsive to Item 303 (a)(5) of Regulation S-K is not required of smaller reporting companies.
Off-Balance Sheet Arrangements
As of December 31, 2020, we do not have material off-balance sheet arrangements.
Impact of Inflation/Deflation and Pricing
All of our transactions are requireddenominated in U.S. dollars. Typically, as prices for oil and natural gas increase, associated costs rise. Conversely, as prices for oil and natural gas decrease, costs decline. Cost declines tend to remeasurelag and may not adjust downward in proportion to decline commodity prices. Historically, field-level prices received for our oil and natural gas production have been volatile. During the deferred taxyear ended December 31, 2020, commodity prices decreased during the first and second quarters and subsequently increased in the third and fourth quarters. During the year ended December 31, 2019, commodity prices decreased during the first quarter, increased in the second quarter, and subsequently decreased in the third quarter and fourth quarter. Changes in commodity prices impact our revenues, estimates of reserves, assessments of any impairment of oil and natural gas properties, as well as values of properties being acquired or sold. Price changes have the potential to affect our ability to raise capital, borrow money, and retain personnel.

Critical Accounting Policies and Estimates
Use of Estimates in the Preparation of Financial Statements
The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of oil and gas reserves, assets and liabilities and disclosure of contingent assets and liabilities at the rate in which they are expected to reverse. We provisionally recorded an income tax benefit in the amount of $23.4 million related to the remeasurementdate of the net deferred tax liability. We are currently evaluating other potential impactsfinancial statements and the reported amounts of revenues and expenses during the TCJA.reporting period. Significant areas requiring the use of assumptions, judgments and estimates include:


In(1) oil and gas reserves;
(2) depreciation, depletion, amortization and accretion;
(3) cash flow estimates used in impairment testing of oil and gas proved and unproved properties;
(4) valuation of commodity derivative instruments;
(5) assigning fair value and allocating purchase price in connection with business combinations, including the IPO in October 2016, our accounting predecessor, Extraction Oil & Gas Holdings, LLC ("Holdings") was merged into the Company. Prior to this corporate reorganization, we were not subject to federal or state income taxes. Accordingly, the financial data attributable to us prior to such corporate reorganization contain no provision for federal or statedetermination of any resulting goodwill;
(6) asset retirement obligations;
(7) accrued revenue and related receivables;
(8) valuation of stock-based payments,
(9) income taxes, because the tax liability with respect to Holdings’ taxable income was passed through toand
(10) bankruptcy proceedings.

Although management believes these estimates are reasonable, actual results could differ from these estimates. We evaluate our members. Beginning October 12, 2016,estimates on an on-going basis and base our estimates on historical experience and on various other assumptions we beganbelieve to be taxed as a C corporationreasonable under the Code and subject to federal and state income taxes at a blended statutory rate of approximately 38% of pretax earnings.circumstances. Although actual results may differ from these estimates under different assumptions or conditions, we believe our estimates are reasonable.
 
How We Evaluate Our Operations
71

Successful Efforts Method of Accounting
 
We use a varietyfollow the successful efforts method of financial and operational metrics to assess the performance of ouraccounting for oil and gas operations, including:properties. Under this method of accounting, all property acquisition costs and development costs are capitalized when incurred and depleted on a units-of-production basis over the remaining life of proved reserves and proved developed reserves, respectively.
 
SourcesThe costs of revenue;exploratory wells are initially capitalized pending a determination of whether proved reserves have been found. At the completion of drilling activities, the costs of exploratory wells remain capitalized if a determination is made that proved reserves have been found. If no proved reserves have been found, the costs of exploratory wells are charged to expense. In some cases, a determination of proved reserves cannot be made at the completion of drilling, requiring additional testing and evaluation of the wells. Cost incurred for exploratory wells that find reserves that cannot yet be classified as proved are capitalized if (a) the well has found a sufficient quantity of reserves to justify its completion as a producing well and (b) sufficient progress in assessing the reserves and the economic and operating viability of the project has been made. The status of suspended well costs is monitored continuously and reviewed quarterly. Due to the capital-intensive nature and the geographical characteristics of certain projects, it may take an extended period of time to evaluate the future potential of an exploration project and the economics associated with making a determination of its commercial viability.

Sales volumes;Geological and geophysical costs are expensed as incurred. Costs of seismic studies that are utilized in development drilling within an area of proved reserves are capitalized as development costs. Amounts of seismic costs capitalized are based on only those blocks of data used in determining development well locations. To the extent that a seismic project covers areas of both developmental and exploratory drilling, those seismic costs are proportionately allocated between development costs and exploration expense.
Realized prices
We capitalize interest, if debt is outstanding, during drilling operations in our exploration and development activities.
Oil and Gas Reserves
Our estimates of proved reserves are based on the salequantities of oil, natural gas and NGL, includingwhich, 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 under existing economic conditions, operating methods and government regulations prior to the effecttime at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. Our independent petroleum engineers, Ryder Scott, prepare a reserve and economic evaluation of all of our commodity derivative contracts;properties on a well-by-well basis. The accuracy of reserve estimates is a function of the: 
Lease operating expenses (“LOE”);
Capital expenditures;quality and quantity of available data;
Adjusted EBITDAX (a Non-GAAP measure).interpretation of that data;
accuracy of various mandated economic assumptions; and
judgment of the independent reserve engineer.
 
SourcesOne of Our Revenues
Our revenues are derived from the salemost significant estimates we make is the estimate of our oil and natural gas production, as well as the sale of NGL that are extracted from our natural gas during processing. Our oil, natural gas and NGL revenues do not include the effects of derivatives. For the year ended December 31, 2017, our revenues were derived 70% from oil sales, 15% fromreserves. Oil, natural gas sales and 15% from NGL sales. Forreserve estimates require significant judgments in the year ended December 31, 2016, our revenues were derived 70% from oil sales, 17% from natural gas salesevaluation of all available geological, geophysical, engineering and 13% from NGL sales. For the year ended December 31, 2015, our revenues were derived 79% from oil sales, 13% from natural gas sales and 8% from NGL sales. Our revenueseconomic data. The data for a given field may vary significantly from period to periodchange substantially over time as a result of changesnumerous factors including, but not limited to, additional development activity, production history, projected future production, economic assumptions relating to commodity prices, operating expenses, severance and other taxes, capital expenditures and remediation costs and these estimates are inherently uncertain. For example, if estimates of proved reserves decline, our DD&A rate will increase, resulting in volumesa decrease in net income. A decline in estimates of proved reserves could also cause us to perform an impairment analysis to determine if the carrying amount of oil and gas properties exceeds fair value and could result in an impairment charge, which would reduce earnings. We cannot predict what reserve revisions may be required in future periods.
Ryder Scott estimated all of our proved reserve quantities as of December 31, 2020 and 2019. In connection with Ryder Scott performing their independent reserve estimations, we furnish them with the following information that they review: (1) technical support data, (2) technical analysis of geologic and engineering support information, (3) economic and production sold or changes in commodity prices.

Sales Volumesdata and (4) our well ownership interests.
 
The following table presents historical sales volumes forinformation about proved reserve changes from period to period due to items we do not control, such as price, and from changes due to production history and well performance. These changes do not require a capital expenditure on our properties for the periods indicated:part, but may have resulted from capital expenditures we incurred to develop other estimated proved reserves.

As reservoir pressures decline, production from a given well or formation decreases. GrowthDeclines in our future production and reserves will depend on our ability to continue to add or develop proved reserves in excess of our production. Accordingly, we plan to maintain our focus on adding reserves through organic growth as well as acquisitions. Our ability to add reserves through development projects and acquisitions is dependent on many factors, including takeaway capacity in our areas of operation and our ability to raise capital, obtain regulatory approvals, procure contract drilling rigs and personnel and successfully identify and consummate acquisitions. Please read “Risks Related to the Oil, Natural Gas and NGL Industry and Our Business” in Item 1A. of this Annual Report for a further description of the risks that affect us.
Realized Prices on the Sale of Oil, Natural Gas and NGL
Our results of operations depend upon many factors, particularly the price of oil, natural gas and NGL prices increase the uncertainty as to the impact of commodity prices on our estimated proved reserves. We are unable to predict future commodity prices with any greater precision than the futures market. A prolonged period of depressed commodity prices may have a significant impact on the value and volumetric quantities of our abilityproved reserve portfolio, assuming no other changes to market our development plans or costs.
Depreciation, Depletion, Amortization and Accretion
Our DD&A rate is dependent upon our estimates of total proved and proved developed reserves, which incorporate various assumptions and future projections. If our estimates of total proved or proved developed reserves decline, the rate at which we record DD&A expense increases, which in turn reduces our net income. Such a decline in reserves may result from lower commodity prices or other changes to reserve estimates, as discussed above, and we are unable to predict changes in reserve quantity estimates as such quantities are dependent on the success of our exploration and development program, as well as future economic conditions.
Impairment of Proved Oil and Gas Properties
Proved oil and gas properties are reviewed for impairment annually or when events and circumstances indicate a possible decline in the recoverability of the carrying amount of such property. We estimate the expected future cash flows of our oil and gas properties and compares these undiscounted cash flows to the carrying amount of the oil and gas properties to determine if the carrying amount is recoverable. If the carrying amount exceeds the estimated undiscounted future cash flows, we will write down the carrying amount of the oil and gas properties to fair value. The factors used to determine fair value include, but are not limited to, estimates of reserves, future commodity prices, future production effectively. Oil, naturalestimates, estimated future capital expenditures, estimated future operating costs, and discount rates commensurate with the risk associated with realizing the projected cash flows. Impairment expense for proved oil and gas properties is reported in impairment of long lived assets and NGL prices are amonggoodwill in the most volatileconsolidated statements of alloperations, which increases accumulated depletion, depreciation and amortization.
Future commodity prices. For example, during the period from January 1, 2014 to December 31, 2017, average daily pricespricing for NYMEXoil is based on five-year West Texas Intermediate oilstrip prices, rangedwhich decreased 14.0% from a highan average of $107.26 per $53.65/Bbl at December 31, 2019 to a lowan average of $26.21 per Bbl. Average daily prices$46.14/Bbl at December 31, 2020. Future commodity pricing for NYMEX Henry Hub gas ranged from a high of $6.15 per MMBtu to a low of $1.64 per MMBtu during the same period. Declines in, and continued depression of, the price of oil and natural gas occurring during 2015 and continuing during 2017 are due to a combination of factors including increased U.S. supply, global economic concerns and geopolitical risks. These price variations can have a material impact on our financial results and capital expenditures.
Oil pricing is predominately driven by the physical market, supply and demand, financial markets and national and international politics. The NYMEX WTI futures price is a widely used benchmark in the pricing of domestic and imported oil in the United States. The actual prices realized from the sale of oil differ from the quoted NYMEX WTI price as a result of quality and location differentials. In the DJ Basin, oil is sold under various purchase contracts with monthly pricing provisions based on NYMEX pricing, adjusted for differentials.

Natural gas prices vary by region and locality, depending upon the distance to markets, availability of pipeline capacity and supply and demand relationships in that region or locality. The NYMEX Henry Hub price of natural gas is a widely used benchmark for the pricing of natural gas in the United States. Similar to oil, the actual prices realized from the sale of natural gas differ from the quoted NYMEXbased on five-year Henry Hub price as a resultstrip prices, which increased 4.9% from an average of quality and location differentials. For example, wet natural gas with a high Btu content sells$2.42/MMBtu at a premiumDecember 31, 2019 to low Btu content dry natural gas because it yields a greater quantityan average of NGL. Location differentials to NYMEX Henry Hub prices result from variances in transportation costs based on the natural gas’ proximity to the major consuming markets to which it is ultimately delivered. Also affecting the differential is the processing fee deduction retained by the natural gas processing plant, generally in the form of percentage of proceeds. The price we receive$2.54/MMBtu at December 31, 2020. Future commodity pricing for our natural gas produced in the DJ BasinNGLs is based on CIGfive-year WTI strip prices, adjusted for certain deductions.which decreased 10.7% from an average of $14.40/Bbl at December 31, 2019 to an average of $12.85/Bbl at December 31, 2020.

Our price for NGL producedimpairment analysis requires us to apply judgment in the DJ Basin is based on a combinationidentifying impairment indicators and estimating future cash flows of prices from the Conway hub in Kansas and Mont Belvieu in Texas where this production is marketed.
The following table provides the high and low prices for NYMEX WTI and NYMEX Henry Hub prompt month contract prices and our differential to the average of those benchmark prices for the periods indicated. The differential varies, but our oil, natural gas and NGL normally sells at a discount to the NYMEX WTI and NYMEX Henry Hub price, as applicable.

Derivative Arrangements
To achieve more predictable cash flow and to reduce our exposure to adverse fluctuations in commodity prices, from time to time we enter into derivative arrangements for our oil and natural gas production. By removing a significant portionproperties. If actual results are not consistent with our assumptions and estimates or our assumptions and estimates change due to new information, we may be exposed to an impairment charge.

For the year ended December 31, 2020, our impairment expense related to oil and gas properties was $197.9 million. We recognized $3.6 million related to impairment of price volatilitythe proved oil and gas properties in our northern field and $194.3 million related to assets in one of our Core DJ Basin fields, as the fields’ fair values did not exceed the carrying amounts associated with our proved oil production, we believe we will mitigate, but not eliminate,and gas properties. For the potential negative effectsyear ended December 31, 2019, our impairment expense was $1.3 billion.

However,northern field and $1.3 billion related to assets in a portionone of our current positions,Core DJ Basin fields as the fields’ fair values did not exceed the carrying amounts associated with our hedging activity may also reduce our ability to benefit from increases inproved oil and natural gas prices. We will sustain losses toproperties.


the extent our derivatives contract prices are lower than market prices and, conversely, we will realize gains to the extent our derivatives contract prices are higher than market prices. In certain circumstances, where we have unrealized gains in our derivative portfolio, we may choose to restructure existing derivative contracts or enter into new transactions to modify the terms of current contracts in order to realize the current value of our existing positions. See “—Quantitative and Qualitative Disclosure About Market Risk—Commodity Price Risk” for information regarding our exposure to market risk, including the effects of changes inForward commodity prices and our commodity derivative contracts.
We will continue to use commodity derivative instruments to hedge our price riskestimates of future production play a significant role in the future. Our hedging strategydetermining impairment of proved oil and future hedging transactions will be determined at our discretion and may be different than what we have done on a historical basis.gas properties. As a result of recent volatilitylower commodity prices and their impact on our estimated future cash flows, we will continue to review our proved oil and gas properties for impairment. After our fourth quarter 2020 impairment charges in two of our Core DJ Basin fields at December 31, 2020, the carrying value of our oil and gas properties exceeded our expected undiscounted future cash flows for proved and risk-adjusted probable and possible reserves by approximately $56.8 million and $340.3 million, in each field. After our fourth quarter 2019 impairment charges in two of our Core DJ Basin fields at

December 31, 2019, the carrying value of our oil and gas properties exceeded our expected undiscounted future cash flows for proved and risk-adjusted probable and possible reserves by approximately $33.8 million and $1.2 billion, in each field. At December 31, 2018, our expected undiscounted future cash flows exceeded the carrying value of our proved oil and gas properties by approximately $0.8 billion, or 30%.
Abandonment of Unproved Oil and Gas Properties
Unproved oil and gas properties consist of costs to acquire unevaluated leases as well as costs to acquire unproved reserves. We evaluate significant unproved oil and gas properties for impairment based on remaining lease term, drilling results, reservoir performance, seismic interpretation or future plans to develop acreage. When successful wells are drilled on undeveloped leaseholds, unproved property costs are reclassified to proved properties and depleted on a unit-of-production basis. Impairment expense and lease extension payments for unproved properties is reported in exploration and abandonment expenses in the priceconsolidated statements of oiloperations. As a result of the abandonment of unproved properties, we recognized $253.1 million and natural gas,$73.7 million in abandonment expense for the years ended December 31, 2020 and 2019, respectively. To the extent we have relied on a variety of hedging strategies and instrumentsdo not elect to hedge our future price risk. renew current leases, we expect further abandonment charges in 2021.

Commodity Derivative Instruments
We have utilizedentered into commodity derivative instruments utilizing swaps put options, and call options, which in some instances require the payment of a premium, to reduce the effect of price changes on a portion of our future oil and natural gas production. We expect to continue to useFor a varietydescription of hedging strategiesour derivative instruments that we utilize and instruments for the foreseeable future.a summary of our open commodity derivative contracts as of December 31, 2020, please see Note 9 — Commodity Derivative Instruments in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report.
 
A swap hasThe commodity derivative instruments are measured at fair value and are included in the accompanying consolidated balance sheets as commodity derivative assets or liabilities. We have not designated any of the derivative contracts as fair value or cash flow hedges. Therefore, we do not apply hedge accounting to the commodity derivative instruments. Net gains and losses on commodity derivative instruments are recorded based on the changes in the fair values of the derivative instruments. Net gains and losses on commodity derivative instruments are recorded in the commodity derivative gain (loss) line on the consolidated statements of operations. Our cash flow is only impacted when the actual settlements under the commodity derivative contracts result in making or receiving a payment to or from the counterparty. These settlements under the commodity derivative contracts are reflected as operating activities in our consolidated statements of cash flows.
Our valuation estimate takes into consideration the counterparties’ credit worthiness, our credit worthiness, and the time value of money. The consideration of the factors results in an established fixed price. Whenestimated exit-price for each derivative asset or liability under a market participant’s view. We believe that this approach provides a reasonable, non-biased, verifiable, and consistent methodology for valuing commodity derivative instruments. Please see “—How We Evaluate Our Operations—Derivative Arrangements.”

Accounting for Business Combinations

We account for all of our business combinations using the settlementacquisition method, which is the only method permitted under ASC 805, Business Combinations, and involves the use of significant judgment. In connection with a business combination, the acquiring company must allocate the cost of the acquisition to assets acquired and liabilities assumed based on fair values as of the acquisition date. Any excess or shortage of amounts assigned to assets and liabilities over or under the purchase price is belowrecorded as a gain on bargain purchase or goodwill. The amount of goodwill or gain on bargain purchase recorded in any particular business combination can vary significantly depending upon the fixed price,values attributed to assets acquired and liabilities assumed.

In estimating the counterparty pays us an amount equalfair values of assets acquired and liabilities assumed in a business combination, we make various assumptions. The most significant assumptions relate to the difference betweenestimated fair values assigned to proved and unproved oil and gas properties. If sufficient market data is not available regarding the settlement pricefair values of proved and unproved properties, we must prepare estimates. To estimate the fixed price multiplied by the hedged contract volume. When the settlement price is above the fixed price,fair values of these properties, we pay our counterparty an amount equalprepare estimates of gas, oil and NGL reserves. We estimate future prices to apply to the difference betweenestimated reserves quantities acquired and estimate future operating and development costs to arrive at estimates of future net cash flows. For estimated proved reserves, the settlement price and the fixed price multiplied by the hedged contract volume.

A put option has an established floor price. The buyerfuture net cash flows are discounted using a market-based weighted average cost of the put option pays the seller a premium to enter into the put option. When the settlement price is below the floor price, the seller pays the buyer an amount equal to the difference between the settlement price and the strike price multiplied by the hedged contract volume. When the settlement price is above the floor price, the put option expires worthless. Some of our purchased put options have deferred premiums. For the deferred premium puts, we agreed to pay a premium to the counterpartycapital rate determined appropriate at the time of settlement.the acquisition. The market-based weighted average cost of capital rate is subjected to additional project-specific risking factors. To compensate for the inherent risk of estimating and valuing unproved reserves, when a discounted cash flow model is used, the discounted future net cash flows of probable and possible reserves are reduced by additional risk factors. In some instances, market comparable information of recent transactions is used to estimate fair value of unproved acreage.

Estimated fair values assigned to assets acquired can have a significant effect on results of operations in the future. A higher fair value assigned to a property results in higher DD&A expense, which results in lower net earnings. Fair values are based on estimates of future commodity prices, reserves quantities, operating expenses and development costs. This increases the likelihood of impairment if future commodity prices or reserves quantities are lower than those originally used to determine fair value, or if future operating expenses or development costs are higher than those originally used to determine fair value. Impairment would have no effect on cash flows but would result in a decrease in net income for the period in which the impairment is recorded.

Asset Retirement Obligations
 
A call option hasOur asset retirement obligations (“ARO”) consist of estimated future costs associated with the plugging and abandonment of oil, natural gas and NGL wells, removal of equipment and facilities from leased acreage and land restoration in accordance with applicable local, state and federal laws, and applicable lease terms. The fair value of an established ceiling price. The buyer ofARO liability is required to be recognized in the call option pays the seller a premium to enter into the call option. When the settlement priceperiod in which it is above the ceiling price, the seller pays the buyer an amount equal to the difference between the settlement price and the strike price multiplied by the hedged contract volume. When the settlement price is below the ceiling price, the call option expires worthless.
We combine swaps, purchased put options, sold put options, and sold call options in order to achieve various hedging strategies. Some examples of our hedging strategies are collars which include purchased put options and sold call options, three-way collars which include purchased put options, sold put options, and sold call options, and enhanced swaps, which include either sold put options or sold call optionsincurred, with the associated premiums rolled into an enhanced fixed price swap. We have historically relied on commodity derivative contracts to mitigate our exposure to lower commodity prices.

We have historically been able to hedge our oil and natural gas production at prices that are significantly higher than current strip prices. However, in the current commodity price environment, our ability to enter into comparable derivative arrangements at favorable prices may be limited, and we are not obligated to hedge a specific portion of our oil or natural gas production. The following summarizes our derivative positions related to crude oil and natural gas sales in effectasset retirement cost capitalized as of December 31, 2017:

Lease Operating Expenses
All direct and allocated indirect costs of lifting hydrocarbons from a producing formation to the surface constituting part of the current operating expensescarrying cost of a working interest. Such costs include labor, superintendence, supplies, repairs, maintenance, water injectionthe oil and disposal costs, allocated overhead charges, workover, insurancegas asset. The recognition of an ARO requires that management make numerous assumptions regarding such factors as the estimated probabilities, amounts and other expenses incidentaltiming of settlements; the credit-adjusted risk-free discount rate to production, but exclude lease acquisitionbe used; and inflation rates. In periods subsequent to the initial measurement of the ARO, we must recognize period-to-period changes in the liability resulting from the passage of time and revisions to either the timing or drilling or completion expenses. LOE also includes expenses incurredthe amount of the original estimate of undiscounted cash flows. Increases in the ARO liability due to gatherthe passage of time impact net income as accretion expense. The related capitalized cost, including revisions thereto, is charged to expense through DD&A over the life of the oil and delivergas property.
Revenue Recognition
Revenue from the sale of oil, natural gas and NGLs is recognized in accordance with ASC 606 - Revenue from Contracts with Customers five-step revenue recognition model to depict the transfer of goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. To account for producer imbalances, we recognize revenues on all sales of oil, natural gas and NGLs to third party customers regardless of their ownership percentage and adjust the underlifter or overlifter’s claim on the asset’s remaining reserves. In other words, revenue is recorded based on our share of volume sold, regardless of whether we have taken our proportional share of volume produced. A receivable or liability is recognized only to the processing plant and/or selling point.extent that we have an imbalance on a specific property greater than the expected remaining proved reserves. We receive payment one to three months after delivery. At the end of each month, we estimate the amount of production delivered to purchasers and the price we will receive. Variances between our estimates and the actual amounts received are recorded in the month payment is received. A 10% change in our revenue accrual would have impacted total operating revenues by approximately $6.3 million and $10.5 million for the years ended December 31, 2020 and 2019, respectively.

Stock-Based Payments
 
We granted awards under the 2016 LTIP and 2021 LTIP (as defined in Note 14 — Stock-Based Compensation in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report) to certain directors, officers and employees, including stock options, restricted stock units, performance stock awards, performance stock units, performance cash awards and cash awards which therefore required us to recognize the expense in our consolidated financial statements.

All stock-based payments to employees are measured at fair value on the grant date and expensed over the relevant service period. The fair value of stock option awards is determined by using the Black-Scholes option pricing model. The fair value of the PSAs was measured at the grant date with a stochastic process method using a Monte Carlo simulation. All stock-based payment expense is recognized using the straight-line method and is included within general and administrative expenses in the consolidated statements of operations and stock-based compensation in the consolidated statements of cash flows. Forfeitures are recorded as they occur. Please refer to Note 14 — Stock-Based Compensation in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report for additional discussion on stock-based payments.

Capital Expenditures


For the year ended December 31, 2017,2020, we incurred approximately $864.5$159.6 million excluding outstanding elections, in drilling 186and completion capital expenditures. For the year ended December 31, 2020, we drilled 37 gross (137.4(25.7 net) wells with an average lateral length of 1.7approximately 2.3 miles and completing 198completed 45 gross (158.9(34.1 net) wells with an average lateral length of 1.7approximately 2.4 miles. We turned to sales 49 gross (36.5 net) wells with an average lateral length of approximately 2.4 miles. In addition, we incurred approximately $73.2$16.9 million of leasehold and surface acreage additions, excluding acquisitions,additions.

Our 2021 capital budget for the drilling and completion of operated and non-operated wells is approximately $10.9 million of midstream, excluding acquisitions. Our 2017 revised budget allocated approximately $865$140 million to $885 million to the drilling of 185 to 190 gross operated wells and the completion of 190 to 195 gross operated wells, approximately $60.0 million to $80.0 million to undeveloped leasehold, midstream and other capital expenditures, excluding amounts that were paid for acquisitions.

Our 2018 capital budget is approximately $890 million to $990$180 million, substantially all of which we intend to allocate to the Core DJ Basin. We intend to allocate approximately $770 million to $840 million of our 2018 capital budget to operated and non-operated drilling and completion of new wells. We expect to drill 170 to 17534 gross operated wells, complete 49 gross operated wells and complete 185 to

190turn-in-line 44 gross operated wells. Approximately $120 million to $150 million is expected to be allocated to organic undeveloped acreage leasing, midstream, and other capital expenditures. Our 2021 capital budget anticipates a two to three operated rigone-rig drilling program and excludes any amounts that were or may be paid for potential acquisitions.we expect to operate most of the year.
 
The amount and timing of these capital expenditures is within our control and subject to our management’s discretion. We retain the flexibility to defer or accelerate a portion of these planned capital expenditures depending on a variety of factors, including but not limited to the success of our drilling activities, prevailing and anticipated prices for oil, natural gas and NGL, the availability of necessary equipment, infrastructure and capital, the receipt and timing of required regulatory permits and approvals, seasonal conditions, drilling and acquisition costs and the level of participation by other interest owners. Any postponement or elimination of our development drilling program could result in a reduction of proved reserve volumes and related standardized measure. These risks could materially affect our business, financial condition and results of operations.

Adjusted EBITDAX
 
Adjusted EBITDAX is not a measure of net income (loss) as determined by United States generally accepted accounting principles ("GAAP").GAAP. Adjusted EBITDAX is a supplemental non-GAAP financial measure that is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. We define Adjusted EBITDAX as net income (loss)loss adjusted for certain cash and non-cash items, including depletion, depreciation, amortization and accretion ("DD&A")(DD&A), impairment of long lived assets, non-recurring charges in other operating expenses, exploration and abandonment expenses, rig termination fees, acquisition transaction expenses,(gain) loss on sale of property and equipment, commodity derivativederivatives (gain) loss, settlements on commodity derivatives,derivative instruments, premiums paid for derivatives that settled during the period, unit and stock-based compensation expense, amortization of debt discount and debt issuance costs, interest expense, gain on repurchase of senior notes, income taxestax benefit, loss on deconsolidation of Elevation Midstream, LLC and non-recurring charges.reorganization items, net. Adjusted EBITDAX is also used to evaluate the performance of reportable segments. See Note 18 — Segment Information in Part II, Item 8 of this Annual Report for more information regarding the EBITDAX of reportable segments.
 
Management believes Adjusted EBITDAX is useful because it allows us to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to our financing methods or capital structure. We exclude the items listed above from net income (loss) in arriving at Adjusted EBITDAX because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDAX should not be considered as an alternative to, or more meaningful than, net income (loss) as determined in accordance with GAAP or as an indicator of our operating performance. Certain items excluded from Adjusted EBITDAX are significant components in understanding and assessing a company'scompany’s financial performance, such as a company'scompany’s cost of capital, hedging strategy and tax structure, as well as the historic costs of depreciable assets, none of which are components of Adjusted EBITDAX. Our computations of Adjusted EBITDAX may not be comparable to other similarly titled measure of other companies. We believe that Adjusted EBITDAX is a widely followed measure of operating performance. Additionally, our management team believes Adjusted EBITDAX is useful to an investor in evaluating our financial performance because this measure: 
measure (i) is widely used by investors in the oil and natural gas industry to measure a company’s operating performance without regard to items excluded from the calculation of such term, among other factors;
(ii) helps investors to more meaningfully evaluate and compare the results of our operations from period to period by removing the effect of our capital structure from our operating structure; and
(iii) is used by our management team for various purposes, including as a measure of operating performance, in presentations to our board of directors, as a basis for strategic planning and forecasting. Adjusted EBITDAX is also used by our Board of Directors as a performance measure in determining executive compensation.

Free Cash Flow

Our Free Cash Flow is not a measure of net income (loss) as determined by GAAP. We define Free Cash Flow as Discretionary Cash Flow (non-GAAP) less Adjusted Cash Flow used in Investing (non-GAAP) adjusted for Other Non-Recurring Adjustments (non-GAAP). Discretionary Cash Flow is defined as net cash provided by operating activities (GAAP) less changes in working capital (current assets and liabilities). Adjusted Cash Flow used in Investing is defined as cash flow used in investing activities (GAAP) adjusted for changes in accounts payable and accrued liabilities related to capital expenditures.

Free Cash Flow is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. We believe Free Cash Flow can provide additional transparency into the drivers of trends in our operating cash flows, such as production, realized sales prices and operating costs, as it disregards the timing of settlement of operating assets and liabilities. We believe Free Cash Flow provides additional information that may be useful in an analysis of our ability to generate cash to fund exploration and development activities, construct and support midstream assets, and to return capital to stockholders.

Items Affecting the Comparability of Our Financial Results
 
Our historical results of operations for the periods presented may not be comparable, either to each other or to our future results of operations, for the reasons described below: 


On December 22, 2017,During the TCJA was enacted making significant changes to the Internal Revenue Code. WeChapter 11 Cases, our financial results have calculatedbeen volatile as restructuring activities and expenses, contract terminations and rejections and claims assessments significantly impacted our best estimate of the impact of the TCJA in our year-end income tax provision in accordance with our understanding of the TCJA and guidance available as of the date of this filing. Many of the provisions in the TCJA have an effective date for years beginning after December 31, 2017, including the lowering of the U.S. corporate rate from 35% to 21%. However, as a result of the enactment date of December 22, 2017, we are required to remeasure the deferred tax assets and liabilities at the rate in which they are expected to reverse. We provisionally recorded an income tax benefit in the amount of $23.4 million related to the remeasurement of the net deferred tax liability.

In connection with the consummation of the IPO, we issued 185,280 shares of our Series A Preferred Stock to the holders of Holdings’ Series B Preferred Units in conversion of such units. The Series A Preferred Stock are entitled to receive a cash dividend of 5.875% per year, payable quarterly in arrears, and we have the ability to pay such quarterly dividends in kind at a dividend rate of 10% per year (decreased proportionately to the extent such quarterly dividends are paid in cash).

We incur additional general and administrative expenses related to being a public company, including Exchange Act reporting expenses; expenses associated with Sarbanes-Oxley Act compliance; expenses associated with listing on the NASDAQ Global Select Market; incremental independent auditor fees; incremental legal fees; investor relations expenses; registrar and transfer agent fees; incremental director and officer liability insurance costs; and directors compensation.

Prior to our initial public offering, we were not subject to federal or state income taxes. Accordingly, the financial data attributable to us prior to such corporate reorganization contain no provision for federal or state income taxes

because the tax liability with respect to Holdings’ taxable income was passed through to its members. Beginning October 12, 2016, we began to be taxed as a C corporation under the Code and subject to federal and state income taxes at a blended statutory rate of approximately 38% of pretax earnings.

In October 2016, our board of directors adopted the Extraction Oil & Gas, Inc. 2016 Long Term Incentive Plan ("LTIP") and subsequently granted awards to certain directors, officers and employees, including stock options, restricted stock units and performance stock awards. We recognized $48.3 million and $8.5 million of stock-based compensation expense for years ended December 31, 2017 and 2016, respectively, related to these awards.

On October 3, 2016, we acquired additional oil and gas properties primarily located in the Wattenberg Field located primarily around our existing Greeley and Windsor areas. The October 2016 Acquisition consisted of working interest in approximately 6,400 net acres and 31 gross (19 net) drilled but uncompleted wells, as of the date of acquisition. The October 2016 Acquisition provided net daily production of approximately 6,900 BOE/d.

In 2015, we granted certain members of management incentive units pursuant to Holdings’ 2014 Membership Unit Incentive Plan and its limited liability company agreement. These equity-based awards are subject to time-based vesting requirements, as well as accelerated vesting upon the occurrence of a change of control. In connection with the IPO, the Board of Managers of Holdings accelerated the vesting of the Holdings’ Incentive Units. Our IPO and change of control triggered the conversion of these units into approximately 9.1 million of our common shares based on the 10-day volume weighted average price of our common stock following its IPO as set forth in the 2014 Plan and the Holdings LLC Agreement.results. For the year ended December 31, 2016,2020, we incurred $676.9 million of reorganization items net as compared to none in 2019. As a result, our historical financial performance is likely not indicative of financial performance after the date of the bankruptcy filing. The Company emerged from the Chapter 11 proceedings on January 20, 2021, however claim assessments will continue for months longer.

Elevation Midstream, LLC was deconsolidated as of March 16, 2020 and accounted for as an equity method investment. We elected the fair value option to remeasure the Elevation Midstream, LLC equity method investment and determined it had no fair value. We recorded a $73.1 million loss on deconsolidation of Elevation Midstream, LLC in the consolidated statements of operations for the year ended December 31, 2020. Please see Note 1 — Business and Organization — Deconsolidation of Elevation Midstream, LLC in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report for information related to the deconsolidation of Elevation Midstream, LLC.

For the years ended December 31, 2020 and 2019 we recognized approximately $172.1$194.3 million and $1.3 billion, respectively, in non-cash, share-based compensationimpairment expense on our oil and gas properties related to assets in connection withour Core DJ Basin field and to a much lesser extent in our northern field.

For the conversionyears ended December 31, 2020 and 2019, respectively, exploration and abandonment expenses increased primarily due to the abandonment of the Holdings’ Incentive Units into our common stock.$253.1 million and $73.7 million of unproved properties.


On March 10, 2015, we acquired interests in approximately 39,000 net acres

Oil sales revenues. Crude oil sales revenues increaseddecreased by $225.8$338.9 million to $419.9$382.5 million for the year ended December 31, 20172020 as compared to crude oil sales of $194.1$721.4 million for the year ended December 31, 2016. An increase2019. A decrease in sales volumes between these periods contributed to a $158.0$135.2 million positivenegative impact, while an increaseand a decrease in crude oil prices contributed a $67.8$203.7 million positivenegative impact. Additionally, for the year ended December 31, 2020 crude oil revenue decreased by approximately $12.3 million as compared to a crude oil revenue decrease of approximately $24.7 million for the year ended December 31, 2019 due to a contract term impacting the amount of consideration that can be included in the transaction price which reduced oil sales revenue pursuant to ASC 606.
 
For the year ended December 31, 2017,2020, our crude oil sales averaged 26.334.3 MBbl/d. Our crude oil sales volumes increased 81%decreased 19% to 9,593.7 MBbl in the year ended December 31, 2017 compared to 5,287.412,543 MBbl for the year ended December 31, 2016.2020 compared to 15,436 MBbl for the year ended December 31, 2019. The volume increasedecrease was primarily due to the developmentnatural decline of our properties. Forexisting producing properties, which was partially offset by an increase in production from the completion of 45 wells during the year ended December 31, 2017, we completed 198 gross wells. The increased production from these new wells was offset by the normal decline on the existing producing properties.2020.
 
The average price we realized on the sale of crude oil was $43.77$30.50 per Bbl for the year ended December 31, 20172020 compared to $36.70$46.74 per Bbl for the year ended December 31, 2016.2019, primarily due to changes in market prices for crude oil and the $12.3 million and $24.7 million decrease of crude oil revenue explained above.
 
Natural gas sales revenues.  Natural gas sales revenues increaseddecreased by $43.6$12.2 million to $92.3$96.7 million for the year ended December 31, 20172020 as compared to natural gas sales revenues of $48.7$108.9 million for the year ended December 31, 2016.2019. An increase in sales volumes between these periods contributed a $29.3$12.8 million positive impact, while an increasea decrease in natural gas prices contributed a $14.3$25.0 million positivenegative impact.
 
For the year ended December 31, 2017,2020, our natural gas sales averaged 88.8197.6 MMcf/d. Natural gas sales volumes increased by 60%12% to 32,395.272,311 MMcf for the year ended December 31, 20172020 as compared to 20,211.564,710 MMcf for the year ended December 31, 2016.2019. The volume increase was primarily due to the developmentcompletion of our properties. For45 gross wells for the year ended December 31, 2017, we completed 198 gross wells.2020. The increased production from these new wells was partially offset by the normalnatural decline on theof our existing producing properties.
 
The average price we realized on the sale of our natural gas was $2.85$1.34 per Mcf for the year ended December 31, 20172020 compared to $2.41$1.68 per Mcf for the year ended December 31, 2016.2019, primarily due to capacity constraints in transporting the wet gas associated with crude oil production coupled with a negative commodity price environment due to oversupply and a decrease in demand.
 
NGL sales revenues.  NGL sales revenues increased by $56.7$2.1 million to $92.1$77.2 million for the year ended December 31, 20172020 as compared to NGL sales revenues of $35.4$75.1 million for the year ended December 31, 2016.2019. An increase in sales volumes between these periods contributed a $25.0$21.6 million positive impact, while an increasea decrease in price contributed a $31.7$19.4 million positivenegative impact.
 
For the year ended December 31, 2017,2020, our NGL sales averaged 10.721.7 MBbl/d. NGL sales volumes increased by 70%29% to 3,900.97,945 MBbl for the year ended December 31, 20172020 as compared to 2,284.06,164 MBbl for the year ended December 31, 2016.2019. The volume increase wasis primarily due to the developmentcompletion of 45 gross wells for the year ended December 31, 2020. The increased production from these new wells was partially offset by the natural decline of our existing producing properties. Our NGL sales are directly associated with our natural gas sales since the majority ofbecause our natural gas volumes are processed by third parties which return a percentage of the proceeds fromfor both residue natural gas sales and NGL sales.
 
The average price we realized on the sale of our NGL was $23.60$9.72 per Bbl for the year ended December 31, 20172020 compared to $15.49$12.18 per Bbl for the year ended December 31, 2016.2019, primarily due to capacity constraints in transporting the wet gas associated with crude oil production coupled with a negative commodity price environment due to oversupply and a decrease in demand.
 
Lease operating expenses ("LOE").  Our LOE, increaseddecreased by $49.3$19.5 million to $111.3$77.8 million for the year ended December 31, 2017,2020, from $62.0$97.3 million for the year ended December 31, 2016.2019. The increasedecrease in LOE was comprisedprimarily the result of an increase in transportation and gathering (“T&G”) expenseoptimization of $25.6 million forour field cost structure during the year ended December 31, 2017 compared to the year ended December 31, 2016 and an increase in operating expenses of $23.7 million for the year ended December 31, 2017 compared to the year ended December 31, 2016. These increases were primarily due to the development of our properties. For the year ended December 31, 2017, we completed 198 gross wells.
2020. On a per unit basis, LOE increased $0.22 per BOE from $5.67decreased to $2.39 per BOE sold for the year ended December 31, 2016 to $5.892020 from $3.00 per BOE sold for the year ended December 31, 2017. The increase was comprised2019.

Transportation and gathering. Our T&G expense of $0.39 per BOE from $2.31 per BOE for the year ended December 31, 2016 to $2.70 per BOE for the year ended December 31, 2017 and a decrease in operating expenses of $0.17 per BOE from $3.36 per BOE for the year ended December 31, 2016 to $3.19 per BOE for the year ended December 31, 2017. The increase in LOE was primarily the result of an increase in both residue natural gas and NGL sales volumes and realized prices, resulting in collectively higher T&G expense. As a result of the January 1, 2018 adoption of Accounting Standard Update 2014-09, Revenue from Contracts with Customers (Topic 606), we expect T&G expense to decrease as a result of a change in accounting methodology for certain contracts where title of

production transfers to customers at the wellhead, in these circumstances T&G expense will be netted against the associated sales revenue.
Production taxes.  Our production taxes increased by $30.7$85.5 million to $51.4$138.6 million for the year ended December 31, 2017 as compared to $20.72020, from $53.1 million for the year ended December 31, 2016.2019. The increase in T&G is primarily attributable to an increase of volumes on a certain gathering system and a change in oil contracts.

On a per unit basis, T&G increased to $4.26 per BOE sold for the year ended December 31, 2020 from $1.64 per BOE sold for the year ended December 31, 2019.
Production taxes.  Our production taxes decreased by $39.2 million to $29.0 million for the year ended December 31, 2020 as compared to $68.2 million for the year ended December 31, 2019. The decrease was attributable to increaseddecreased revenue as State of Colorado production taxes are calculated as a percentage of sales revenue. Production taxes as a percentage of sales revenue was 8.5%5.2% for the year ended December 31, 20172020 as compared to 7.5% for the year ended December 31, 2016.2019. The increasedecrease in production taxes as a percentage of sales revenue relates to an increasea decrease in the estimated ad valorem and severance tax rates forand an adjustment to the year endedestimated ad valorem tax payable as of December 31, 2017.2020.
 
Exploration and abandonment expenses.  Our exploration and abandonment expenses were $36.3$258.9 million and $36.4$88.8 million for the years ended December 31, 20172020 and 2016,2019, respectively. We recognized $18.7$4.9 million in expense attributable to the extension of certain leases $15.8and $253.1 million in expense attributable to the abandonment and impairment of unproved properties and $1.4 million of costs associated with exploratory geological and geophysical costs for the year ended December 31, 2017. We recognized $14.1 million in expense attributable to the extension of leases and $22.3 million in expense attributable to the abandonment and impairment of unproved properties for the year ended December 31, 2016.2020. We recognized $12.4 million in expense attributable to the extension of certain leases and $73.7 million in expense attributable to the abandonment of unproved properties for the year ended December 31, 2019.
 
Depletion, depreciation, amortization and accretion expense (“DD&A”).expense.  Our DD&A expense increased $109.7decreased $192.2 million to $315.0$332.3 million for the year ended December 31, 20172020 as compared to $205.3$524.5 million for the year ended December 31, 2016.2019. This increasedecrease was due to higher volumes sold foran impairment of $1.3 billion of proved oil and gas properties that occurred during the year ended December 31, 2017 as sales increased by approximately 7,954.0 MBoe.fourth quarter of 2019. On a per unit basis, DD&A expense decreased from $18.77$16.20 per BOE for the year ended December 31, 20162019 to $16.67$10.21 per BOE for the year ended December 31, 2017. The decrease in DD&A per BOE is due to an increase in reserves related to an increase in prices and extensions, slightly offset by increased production for the year ended December 31, 2017.2020.
 
Impairment of long lived assets.  For the year ended December 31, 2017,2020, our impairment expense was $1.6$208.5 million, associated withrelated to the impairment onof other property and equipment, and certain well equipment inventory, evaluated to have a net realizable value less thanand the impairment of oil and gas properties in our Core DJ Basin field as the field’s fair values did not exceed the carrying value, as the equipment was determined to no longer be useful inamounts associated with our current drilling operations.proved oil and gas properties. For the year ended December 31, 2016, we recognized $22.5 million in2019, our impairment expense on proved oil and gas properties in our northern field. The future undiscounted cash flows did not exceed its carrying amount associated with itswas $1.3 billion. We recognized $14.5 million related to impairment of the proved oil and gas properties in our northern field and it$1.3 billion of impairment expense was determined that the proved oil and gas properties had no remaining fair value. Therefore, the full net book value of these proved oil and gas properties were impaired at June 30, 2016. Additionally,recognized for the year ended December 31, 2016 we recognized $0.9 million2019 on proved oil and gas properties in our Core DJ Basin field.
(Gain) loss on sale of impairment on other property and equipment. 
Other operating expenses.    Other operating expenses for the year ended December 31, 2017 is comprisedequipment and assets of a $0.5 million lossunconsolidated subsidiary.  Our gain on the sale of insignificant property and equipment. Other operating expenses for the year ended December 31, 2016 includes $10.0 million on the write off of a non-refundable payment related to an option to acquire additional acreage. In March 2017, we entered into an amendment to this agreement with Bayswater to terminate both our and Bayswater’s options for no further consideration. Also included in other operating expenses for the year ended December 31, 2016 is a $0.9 million rig termination fee related to the early termination of a rig in February 2016.
Acquisition transaction expenses.  There were no significant acquisition transaction expenses for the year ended December 31, 2017. As part of the acquisition of properties in August 2016 and October 2016, we incurred $2.7 million of transaction costs associated with a finder’s fee, legal expenses and due diligence for the year ended December 31, 2016.
General and administrative expenses (“G&A”).  General and administrative expenses decreased by $122.2 million to $110.2was $0.1 million for the year ended December 31, 20172020, as compared to $232.4a $0.4 million loss for the year ended December 31, 2019, which was related to our March 2019 Divestiture, August 2019 Divestiture and December 2019 Divestitures.

Commodity derivative gain (loss).  Primarily due to the unwinding of trades due to the commencement of the Chapter 11 Cases, coupled with the decrease in NYMEX crude oil futures prices at December 31, 2020 as compared to December 31, 2019 and change in fair value from the execution of new positions, we incurred a net gain on our commodity derivatives of $165.0 million for the year ended December 31, 2017. The decrease in other G&A expenses on a per BOE basis is due to higher production volumes for the year ended December 31, 2017.
Commodity derivative gain (loss).2020. Primarily due to the increase in NYMEX crude oil futures prices at December 31, 20172019 as compared to December 31, 2016 and change in fair value from the execution of new positions during each period, we incurred a net loss on our commodity derivatives of $36.3 million and $100.9 million for the years ended December 31, 2017 and 2016, respectively. These losses are a result of our hedging program, which is used to mitigate our exposure to commodity price fluctuations. The fair value of the open commodity derivative instruments will continue to change in value until the transactions are settled. Therefore, we expect our net income (loss) to reflect the volatility of commodity price forward markets. Our cash flow will only be affected upon settlement of the transactions at the current market prices at that time. For the year ended December 31, 2017, we distributed cash settlements of commodity derivatives totaling $18.0 million. For the year ended December 31, 2016, we received cash settlements of commodity derivatives totaling $34.2 million.
Interest expense.  Interest expense consists of interest paid and accrued on our long term debt, amortization of debt discount and debt issuance costs, net of capitalized interest. For the year ended December 31, 2017, we recognized interest expense of approximately $51.9 million as compared to $68.8 million for the year ended December 31, 2016, as a result of borrowings under our revolving credit facility, our Second Lien Notes in 2016, our 2021 Senior Notes, our 2024 Senior Notes in 2017 and the amortization of debt issuance costs and debt discount.
We incurred interest expense for the year ended December 31, 2017 of approximately $58.7 million related to our 2024 Senior Notes, 2021 Senior Notes and credit facility. We incurred interest expense for the year ended December 31, 2016 of approximately $50.4 million related to our Second Lien Notes, our 2021 Senior Notes and credit facility. Also included in interest expense for the years ended December 31, 2017 and 2016 was the amortization of debt issuance costs and debt discount of $4.3 million and $4.2 million, respectively. For the years ended December 31, 2017 and 2016, we capitalized interest expense of $11.1 million and $5.2 million, respectively. Also included in interest expense for the year ended December 31, 2016 is a prepayment penalty of $4.3 million and the accelerated amortization of our remaining unamortized debt discount and debt issuance costs of $15.1 million related to the our repayment of the Second Lien Notes in July 2016.

Income tax benefit.  We recorded an income tax benefit of approximately $63.7 million and $29.3 million resulting in an effective tax rate of approximately 58.9% and 6.0% for the years ended December 31, 2017 and 2016, respectively. Our effective tax rate for 2017 differs from the U.S. statutory income tax rate of 38.0% primarily due to the effects of state income taxes, estimated permanent taxable differences and a one-time remeasurement of net deferred tax liabilities from 38.0% to 24.7% due to the Tax Cuts and Jobs Act. During the year ended December 31, 2017, our income tax benefit increased $34.4 million compared to the same period in 2016, which was primarily due to the one-time remeasurement of net deferred tax liabilities in 2017 and our corporate reorganization to a C-Corp in 2016. Excluding the impact of the one-time remeasurement of net deferred tax liabilities required in 2017, our overall effective tax rate was 37.3% for the year ended December 31, 2017.
Year Ended December 31, 2016 Compared to Year Ended December 31, 2015
Oil sales revenues. Crude oil sales revenues increased by $37.1 million to $194.1 million for the year ended December 31, 2016 as compared to crude oil sales of $157.0 million for the year ended December 31, 2015. An increase in sales volumes between these periods contributed a $53.4 million positive impact, while a decrease in crude oil prices contributed a $16.3 million negative impact.
For the year ended December 31, 2016, our crude oil sales averaged 14.4 MBbl/d. Our crude oil sales volume increased 34% to 5,287.4 MBbl in the year ended December 31, 2016 compared to 3,945.6 MBbl for the year ended December 31, 2015. The volume increase was primarily due to the development of our properties. For the year ended December 31, 2016, we completed 72 gross wells. The increased production from these new wells was offset by the normal decline on the existing producing properties.

The average price we realized on the sale of crude oil was $36.70 per Bbl for the year ended December 31, 2016 compared to $39.80 per Bbl for the year ended December 31, 2015.
Natural gas sales revenues.  Natural gas sales revenues increased by $22.7 million to $48.7 million for the year ended December 31, 2016 as compared to natural gas sales revenues of $26.0 million for the year ended December 31, 2015. An increase in sales volumes between these periods contributed $22.7 million positive impact, while the change in natural gas prices had a de minimis impact.
For the year ended December 31, 2016, our natural gas sales averaged 55.2 MMcf/d. Natural gas sales volumes increased by 87% to 20,211.5 MMcf for the year ended December 31, 2016 as compared to 10,823.0 MMcf for the year ended December 31, 2015. The volume increase was primarily due to the development of our properties. For the year ended December 31, 2016, we completed 72 gross wells. The increased production from these new wells was offset by the normal decline on the existing producing properties.
The average price we realized on the sale of our natural gas was $2.41 per Mcf for the year ended December 31, 2016 compared to $2.40 per Mcf for the year ended December 31, 2015.
NGL sales revenues.  NGL revenues increased by $20.7 million to $35.4 million for the year ended December 31, 2016 as compared to NGL revenues of $14.7 million for the year ended December 31, 2015. An increase in sales volumes between these periods contributed a $10.5 million positive impact, while an increase in price contributed a $10.2 million positive impact.
For the year ended December 31, 2016, our NGL sales averaged 6.2 MBbl/d. NGL sales volumes increased by 71% to 2,284.0 MBbl for the year ended December 31, 2016 as compared to 1,334.6 MBbl for the year ended December 31, 2015. The volume increase was due to the development of our properties. Our NGL sales are directly associated with our natural gas sales since the majority of our natural gas volumes are processed by third parties which return a percentage of the proceeds from both residue natural gas sales and NGL sales.
The average price we realized on the sale of our NGL was $15.49 per Bbl for the year ended December 31, 2016 compared to $11.02 per Bbl for the year ended December 31, 2015.
Lease operating expenses.  Our LOE, increased by $31.4 million to $62.0 million for the year ended December 31, 2016, from $30.6 million for the year ended December 31, 2015. The increase in LOE was comprised of an increase in transportation and gathering (“T&G”) expense of $18.7 million for the year ended December 31, 2016 compared to the year ended December 31, 2015 and an increase in operating expenses of $12.7 million for the year ended December 31, 2016 compared to the year ended December 31, 2015.
On a per unit basis, LOE, increased $1.35 per BOE from $4.32 per BOE sold for the year ended December 31, 2015 to $5.67 per BOE sold for the year ended December 31, 2016. The increase was comprised of an increase in T&G expense of $1.38 per BOE from $0.93 per BOE for the year ended December 31, 2015 to $2.31 per BOE for the year ended December 31, 2016. The increase in T&G per BOE was offset by a decrease in operating expenses of $0.03 per BOE from $3.39 per BOE for the year ended December 31, 2015 to $3.36 per BOE for the year ended December 31, 2016. The increase in LOE was primarily the result of an increase in T&G fees on gas sales as a result of us entering into more fee-type gas transportation contracts versus percent of proceeds gas transportation contracts.
Production taxes.  Our production taxes increased by $3.7 million to $20.7 million for the year ended December 31, 2016 as compared to $17.0 million for the year ended December 31, 2015. The increase was attributable to increased revenue as State of Colorado production taxes are calculated as a percentage of sales revenue. Production taxes as a percentage of sales revenue was 7.5% for the year ended December 31, 2016 as compared to 8.6% for the year ended December 31, 2015. Production tax rates can vary depending on the location and the volumes produced from our properties.
Exploration expenses.    Our exploration expenses were $36.4 million and $18.6 million for the years ended December 31, 2016 and 2015. We recognized $14.1 million in expense attributable to the extension of leases and $22.3 million in expense attributable to the abandonment and impairment of unproved properties for the year ended December 31, 2016. We recognized $2.2 million in expense attributable to the extension of leases and $16.4 million in expense attributable to the abandonment and impairment of unproved properties for the year ended December 31, 2015.
Depletion, depreciation, amortization and accretion expense (“DD&A”).  Our DD&A expense increased $58.8 million to $205.3 million for the year ended December 31, 2016 as compared to $146.5 million for the year ended

December 31, 2015. This increase was due to higher volumes sold for the year ended December 31, 2016 as sales increased by approximately 3,856.0 MBoe. On a per unit basis, DD&A expense decreased from $20.69 per BOE for the year ended December 31, 2015 to $18.77 per BOE for the year ended December 31, 2016.
Impairment of long lived assets.    For the year ended December 31, 2016, we recognized $22.5 million in impairment expense on proved oil and gas properties in our northern field. The future undiscounted cash flows did not exceed its carrying amount associated with its proved oil and gas properties in our northern field and it was determined that the proved oil and gas properties had no remaining fair value. Therefore, the full net book value of these proved oil and gas properties were impaired at June 30, 2016.  Additionally, for the year ended December 31, 2016 we recognized $0.9 million of impairment on other property and equipment. During 2015, we sold proved oil and gas properties for proceeds of $4.7 million. In connection with the sale, we determined that assets’ net book value exceeded the fair value of such properties by $2.7 million. We recognized that amount as an impairment expense for the year ended December 31, 2015. During 2015, we also recorded impairment expense of $9.5 million related to impairment of a subsidiary. Our subsidiary had negative future undiscounted cash flows associated with its proved oil and gas properties as of December 31, 2015, and it was determined that our subsidiary’s proved oil and gas properties had no remaining fair value. Therefore, our subsidiary’s full net book value of proved oil and gas properties were impaired. Additionally, we recognized $3.6 million in impairment expense related to a specifically proposed gas processing plant that is no longer being pursued.
Other operating expenses.    Other operating expenses for the year ended December 31, 2016 includes $10.0 million on the write off of a non-refundable payment related to an option to acquire additional acreage. In March 2017, we entered into an amendment to this agreement with Bayswater to terminate both our and Bayswater’s options for no further consideration. Also included in other operating expenses for the year ended December 31, 2016 is a $0.9 million rig termination fee related to the early termination of a rig in February 2016. Other operating expenses for the year ended December 31, 2015 were comprised of a $1.7 million rig termination fee related to the early termination of a rig in March 2015 and a rig standby fee of $0.7 million in September 2015. 
Acquisition transaction expenses.  As part of the acquisition of properties in August 2016 and October 2016, respectively, we incurred $2.7 million of transaction costs associated with a finder’s fee, legal expense and due diligence for the year ended December 31, 2016. For the year ended December 31, 2015, we incurred $6.0 million of non-cash transaction costs associated with a finder’s fee to an unaffiliated third-party as part of the acquisition of properties in March 2015. We assigned an overriding royalty interest in the proved and unproved oil and gas properties acquired in March 2015, which had a fair value of $6.0 million on the measurement date, as payment for the finder’s fee.
General and administrative expenses (“G&A”).  General and administrative expenses increased by $195.3 million to $232.4 million for the year ended December 31, 2016 as compared to $37.1 million for the year ended December 31, 2015. This increase was comprised of an increase in unit and stock-based compensation of $194.3 million and an increase in other general and administrative expenses of $1.0 million. On a per unit basis, G&A expenses increased from $5.24 per BOE sold for the year ended December 31, 2015 to $21.24 per BOE sold for the year ended December 31, 2016.
Our G&A expenses includes the non-cash expense for unit and stock-based compensation for equity awards granted to our employees and non-employee consultants. For the year ended December 31, 2016, unit and stock-based compensation expense was $200.3 million as compared to $6.0 million for the year ended December 31, 2015. On a per unit basis, unit and stock-based compensation increased $17.47 per BOE from $0.84 per BOE sold for the year ended December 31, 2015 to $18.31 per BOE sold for the year ended December 31, 2016. The increase in unit and stock-based compensation expense was due to accelerated vesting of outstanding Holdings RUAs in connection with our Corporate Reorganization and IPO. Additionally, as a result of the IPO, Holdings incentive units were converted to common stock resulting in $172.1 million of stock-based compensation expense. Also, we created a Long Term Incentive Plan, which resulted in the granting of RSUs and stock options to certain board members, officers, and employees.

Our other G&A expenses increased by $1.0 million during the year ended December 31, 2016 compared to the year ended December 31, 2015, primarily due to the growth of the Company, however on a per BOE basis, other G&A expenses per BOE sold decreased $1.47 per BOE sold from $4.40 per BOE sold for the year ended December 31, 2015 to $2.93 per BOE sold for the year ended December 31, 2016. The decrease in other G&A expenses on a per BOE basis is due to increases in production volumes for the year ended December 31, 2016.
Commodity derivative gain (loss).  Primarily due to the increase in NYMEX crude oil futures prices at December 31, 2016 as compared to December 31, 20152018 and change in fair value from the execution of new positions, we incurred a net loss on our commodity derivatives of $100.9 million for the year ended December 31, 2016. Primarily due to the decrease in NYMEX crude oil futures prices at December 31, 2015 as compared to December 31, 2014$37.1 million. These gains and change in fair value

from the execution of new positions, we incurred a net gain on our commodity derivatives of $79.9 million for the year ended December 31, 2015. These losses and gains are a result of our hedging program, which is used to mitigate our exposure to commodity price fluctuations. The fair value of the open commodity derivative instruments will continue to change in value until the transactions are settled and we will likely add to our hedging program.program in the future. Therefore, we expect our net income (loss) to reflect the volatility of commodity price forward markets. Our cash flow will only be affected upon settlement of the transactions at the current market prices at that time. For the years ended December 31, 20162020 and 2015,2019, we received and paid cash settlements of commodity derivatives totaling $34.2$188.8 million and $59.8$5.8 million, respectively.

Loss on deconsolidation of Elevation Midstream, LLC. On March 16, 2020, we deconsolidated Elevation Midstream, LLC.

Liquidity and Capital Resources

Chapter 11 Cases and Effect of Automatic Stay

On June 14, 2020, we filed for relief under Chapter 11 of the Bankruptcy Code. The commencement of a voluntary proceeding in bankruptcy constituted an immediate event of default under the Prior Credit Agreement (defined below) and the indentures governing our Senior Notes, resulting in the automatic and immediate acceleration of all of our outstanding debt under the Prior Credit Agreement and the Senior Notes. Any efforts to enforce payment obligations related to the acceleration of our debt were automatically stayed as a result of the filing of the Chapter 11 Cases, and the creditors’ rights of enforcement are subject to the applicable provisions of the Bankruptcy Code. On June 14, 2020, we also entered into the Restructuring Support Agreement (“RSA”) with certain holders of our Senior Notes to support a restructuring in accordance with the terms set forth therein. As more fully disclosed in Note 1 — Business and Organization and Note 8 Long-Term Debt in Part II, Item 8. Financial Information and Supplementary Data of this Annual Report, the RSA contemplated a financial restructuring which would provide for the treatment of holders of certain claims and existing equity interests. The Plan, which included substantially all terms set forth in the RSA, was approved by the Bankruptcy Court on December 23, 2020 and we emerged from bankruptcy on January 20, 2020.

We continued operations in the ordinary course for the duration of the Chapter 11 Cases funding operations with our DIP Credit Facility (as defined in Note 8 Long-Term Debt in Part II, Item 8. Financial Information and Supplementary Data of this Annual Report along with all capitalized debt terms in this paragraph). Upon emergence from bankruptcy, our Prior Credit Facility and DIP Credit Facility were paid off and we obtained a RBL Credit Facility discussed below.

As a result of the Chapter 11 Cases, our total available liquidity as of December 31, 2020 consisted of cash on hand of $205.9 million and $11.5 million of availability on the DIP Credit Facility. With this liquidity and funds generated from ongoing operations, we funded cash requirements throughout 2020 during the Chapter 11 proceedings. As such, we paid and expect to continue paying vendor and royalty obligations according to the terms of our current contracts.

Sources of Liquidity and Capital Resources
  
Our primary sources of liquidity and capital resources are cash flows generated by operating activities and borrowings under our revolving credit facility. Depending upon market conditions and other factors, we may also issue equity and debt securities if needed.
Historically, our primary sources of liquidity have been borrowings under our revolving credit facility, our Second Lien Notes, our 2021 Senior Notes, our 2024 Senior Notes (please refer to Note 5 — Long Term Debt),Prior Credit Facility, proceeds from notes offerings and preferred stock offerings, equity provided by investors, including our management team, cash from the IPO and Private Placementissuance of preferred stock, and cash flows from operations. To date, ourdivestitures and from the sale of oil, gas and NGL production. Our primary useuses of capital hashave been for the acquisition of oil and gas properties to increase our acreage position, as well as development and exploration of oil and gas properties. As of December 31, 2020, our DIP Credit Facility borrowings were $106.7 million, with $75.0 million total outstanding including amounts that were rolled over from the Prior Credit Facility. Our Prior Credit Facility borrowings net of unamortized debt issuance costs, were approximately $1,023.4$453.7 million and $538.1$470.0 million at December 31, 2017,2020, and December 31, 2016,2019, respectively. We had senior notes totaling $1.1 billion outstanding at December 31, 2020 and December 31, 2019. We also have other contractual commitments, which are described in Note 1316 — Commitments and Contingencies.Contingencies in Part II, Item 8. Financial Information and Supplementary Data of this Annual Report.

Upon emergence from bankruptcy on January 20, 2021 indebtedness under our 2024 and 2026 Senior Notes was discharged in exchange for equity as is explained in Note 1 Business and Organization in Part II, Item 8. Financial Information and Supplementary Data of this Annual Report. Our Prior Credit Facility and DIP Credit Facility were paid off, terminated and replaced by our RBL Credit Facility that has a maximum commitment of $1.0 billion with an initial borrowing base and current elected lending commitments of $500.0 million. The borrowing base will be redetermined semiannually on or around May 1 and November 1 of each year, with one interim “wildcard” redetermination available to us and our administrative agent between scheduled redeterminations during any 12-month period. The next scheduled redetermination will be on or around May 1, 2021.

As of the date of this filing, we have drawn $253.7 million on the RBL Credit Facility. Total funds available for borrowing under our RBL Credit Facility, after giving effect to an aggregate of $0.5 million of undrawn letters of credit, were $245.8 million as of the date of this filing.
 
We plan to continue our practice of enteringenter into hedging arrangements to reduce the impact of commodity price volatility on our cash flow from operations. Under this strategy,operations, or alternatively, we intendmay decide to enter into commodity derivative contracts at times and on terms desiredunwind or restructure the hedging arrangements we previously entered into. The RBL Credit Agreement requires us to maintain commodity hedges covering a portfoliominimum of commodity derivative contracts covering approximately 50% to 70%65% of our projectedanticipated oil and natural gas production over a one to two year period at a given point in time, although we may from time to time hedge more or less than this approximate range.
Based on current expectations, we believe we have sufficient liquidity through our existing cash balances, cash flow from operationsPDP reserves for the succeeding twelve months and available borrowings under our revolving credit facility to execute our current capital program, excluding

any acquisitions we may consummate, make our interest payments on the 2024 Senior Notes and 2026 Senior Notes, and pay dividends on our Series A Preferred Stock.
If cash flow from operations does not meet our expectations, we may reduce our expected level of capital expenditures and/or fund a portion50% of our capital expenditures using borrowings under our revolving credit facility, issuancesanticipated oil and gas production from PDP reserves for the next succeeding twelve months.

Our 20182021 capital budget for the drilling and completion of operated and non-operated wells is approximately $890$140 million to $990$180 million, substantially all of which we intend to allocate to the Core DJ Basin. We intend to allocate approximately $770 million to $840 million of our 2018 capital budget to operated and non-operated drilling and completion of new wells. We expect to drill 170 to 17534 gross operated wells, complete 49 gross operated wells and complete 185 to 190turn-in-line 44 gross operated wells. Approximately $120 million to $150 million is expected to be allocated to acreage leasing, midstream, and other capital expenditures. Our 2021 capital budget anticipates a two to three operated rigone-rig drilling program we expect to operate most of the year.

    We had a Stock Repurchase Program in place that ended in 2019. Spending under this program was $137.0 million and excludes any amounts thatwe repurchased 34.1 million shares during the year ended December 31, 2019. We also had a Senior Notes Repurchase Program in place. Spending under this program during the year ended December 31, 2019 was $39.3 million. No common stock or Senior Notes were or may be paid for potential acquisitions.repurchased during the year ended December 31, 2020.

Net cash provided by operating activitiesactivities.For the year ended December 31, 20172020 as compared to the year ended December 31, 2016, our net cash provided by operating activities increased by $200.6 million, primarily driven by an increase in sales volume of 7,953.8 MBoe and increase in realized price of $6.56 per BOE resulting in a reduction in net loss of $411.6 million. An increase in deferred income tax benefit of $34.4 million and increase in changes in current assets and liabilities of $14.7 million also contributed to this increase. This increase was offset by a decrease of stock-based compensation of $134.7 million and settlements on commodity derivatives of $54.8 million.
Net cash used in investing activitiesFor the year ended December 31, 2017 as compared to the year ended December 31, 2017, our net cash used in investing activities increased by $446.5 million primarily due to an increase of $935.7 million in cash expended for drilling and completion activities and other property and equipment. This increase was offset by a decrease in acquired oil and gas properties of $401.8 million and decrease of $84.4 million in cash held in escrow for acquisitions.
Net cash provided by financing activitiesFor the year ended December 31, 2017 as compared to the year ended December 31, 2016, our net cash provided by financing activities decreased by $827.7 million, primarily as a result of a decrease of $1,243.1 million in proceeds from the issuance of common stock and members units, net of issuance costs, and a decrease of $171.6 million in proceeds from the issuance of preferred units and stock in the year ended December 31, 2016. This decrease was offset by an increase of $315.0 million in borrowings under the credit facility and an increase of $274.0 million in net proceeds and repayments of 2021 Senior Notes, 2026 Senior Notes and Second Lien Notes.

Working Capital
 
Our working capital surplus (deficit)deficit at December 31, 2020 was $(236.7)$369.4 million and $379.1at December 31, 2019 was $240.8 million. However, as of December 31, 2020, many of our current liabilities in the amount of $279.6 million were classified as liabilities subject to compromise (excluding approximately $1.8 billion of debt, accrued interest, damages for rejected and settled contracts and other). Our cash balances totaled $205.9 million and $32.4 million at December 31, 20172020 and 2016, respectively. Our cash balances totaled $6.8 million and $588.7 million at December 31, 2017 and December 31, 2016,2019, respectively.

Due to the amounts that we incur related to our drilling and completion program and the timing of such expenditures, we may incur working capital deficits in the future. We expect that our cash flows from operating activities and availability under our revolving credit facility after application of the net proceeds from the 2026 Senior NotesRBL Credit Facility will be sufficient to fund our working capital needs. We expect that our pace of development, production volumes, commodity prices and differentials to NYMEX prices for our oil, natural gas and NGL production will be the largest variables affecting our working capital.

Revolving Credit Facility
The amount available to be borrowed under our revolving credit facility is subject to a borrowing base that is redetermined semiannually on each May 1 and November 1, and will depend on the volumes of our proved oil and gas reserves and estimated cash flows from these reserves and other information deemed relevant by the administrative agent under our revolving credit facility. As of December 31, 2017, the borrowing base was $525.0 million, and we had $90.0 million of borrowings outstanding under our revolving credit facility. In January 2018, we completed the November 1, 2017 borrowing base redetermination. As a result of the redetermination, the borrowing base increased to $750.0 million. The borrowing base was automatically reduced to $700.0 million in connection with the issuance of the 2026 Senior Notes and is subject to current maximum lending commitments of $650.0 million.
Principal amounts borrowed will be payable on the maturity date, and interest will be payable quarterly for alternate base rate loans and at the end of the applicable interest period for Eurodollar loans. We have a choice of borrowing in Eurodollars or at the alternate base rate. Eurodollar loans bear interest at a rate per annum equal to an adjusted LIBOR rate (equal to the product of: (a) the LIBOR rate, multiplied by (b) a fraction (expressed as a decimal), the numerator of which is the number one and the denominator of which is the number one minus the reserve percentages (expressed as a decimal) on such date at which the administrative agent under our revolving credit facility is required to maintain reserves on ‘Eurocurrency Liabilities’ as defined in and pursuant to Regulation D of the Board of Governors of the Federal Reserve System) plus an applicable margin ranging from 200 to 300 basis points, depending on the percentage of our borrowing base utilized. Alternate base rate loans bear interest at a rate per annum equal to the greatest of (i) the agent bank’s reference rate, (ii) the federal funds effective rate plus 50 basis points and (iii) the adjusted one-month LIBOR rate (as calculated above) plus 100 basis points, plus an applicable margin ranging from 100 to 200 basis points, depending on the percentage of our borrowing base utilized. As of December 31, 2017, we had $90.0 million of outstanding borrowings under our revolving credit facility. We may repay any amounts borrowed prior to the maturity date without any premium or penalty other than customary LIBOR breakage costs.
The revolving credit facility is secured by liens on substantially all of our properties and guarantees from us and our current and future subsidiaries, with the exception of Elevation Midstream, LLC. The revolving credit facility contains restrictive covenants that may limit our ability to, among other things:

incur additional indebtedness;
sell assets;
make loans to others;
make investments;
make certain changes to our capital structure;
make or declare dividends;
hedge future production or interest rates;
enter into transactions with our affiliates;
incur liens; and
engage in certain other transactions without the prior consent of the lenders.
The revolving credit facility requires us to maintain the following financial ratios:
a current ratio, which is the ratio of our consolidated current assets (includes unused commitments under our revolving credit facility and unrestricted cash and excludes derivative assets) to our consolidated current liabilities (excludes obligations under our revolving credit facility, the senior notes and certain derivative liabilities), of not less than 1.0 to 1.0 as of the last day of any fiscal quarter; and
a net leverage ratio, which is the ratio of (i) consolidated debt less cash balances to (ii) our consolidated EBITDAX for the four fiscal quarter period most recently ended, not to exceed 4.0 to 1.0 as of the last day of such fiscal quarter; provided that (a) for the quarter ending December 31, 2017, consolidated EBITDAX will be based on the last nine months' consolidated EBITDAX multiplied by 4/3 and (b) for the quarters ending on or after March 31, 2018, consolidated EBITDAX will be based on the last twelve months’ consolidated EBITDAX.

2021 Senior Notes
In July 2016, we closed a private offering of our 2021 Senior Notes that resulted in net proceeds of approximately $537.2 million. Our 2021 Senior Notes bore interest at an annual rate of 7.875% and matured on July 15, 2021.

As a result, on January 25, 2018 we made a cash payment of approximately $534.2 million, which included principal of approximately $500.6 million, a make-whole premium of approximately $32.6 million and accrued and unpaid interest of approximately $1.0 million.

On February 17, 2018, we redeemed the approximately $49.4 million aggregate principal amount of the 2021 Senior Notes that remained outstanding after the Tender Offer and made a cash payment of approximately $52.7 million to the remaining holders of the 2021 Senior Notes, which includes a make-whole premium of $3.0 million and accrued and unpaid interest of approximately $0.3 million.

Convertible Preferred Securities
We previously issued to affiliates of Apollo $75.0 million in Series A Preferred Units to fund a portion of the purchase price for the Bayswater Acquisition. The Series A Preferred Units were entitled to receive a cash dividend of 10% per year, payable quarterly in arrears. We used $90.0 million of the net proceeds from the IPO to redeem the Series A Preferred Units in full, which included a premium of $15.0 million.
In addition, we issued to, among others, investment funds affiliated with OZ Management LP and Yorktown $185.3 million in Series B Preferred Units to fund a portion of the purchase price for the Bayswater Acquisition. The Series B Preferred Units were entitled to receive a cash dividend of 10% per year, payable quarterly in arrears, and we had the ability to pay up to 50% of the quarterly dividend in kind. The Series B Preferred Units were converted in connection with the closing of the IPO into shares ofarrangements including our Series A Preferred Stock that are entitled to receive a cash dividend of 5.875% per year, payable quarterlyand Elevation Preferred Units, please see Note 12 — Equity in arrears, and we have the ability to pay such quarterly dividends in kind at a dividend rate of 10% per year (decreased proportionately to the extent such quarterly dividends are partially paid in cash).

(1)We lease two office spaces in Denver, Colorado, two office spaces in Greeley, Colorado and one office space in Houston, Texas under four separate operating lease agreements. The Denver, Colorado leases expire on February 29, 2020 and May 31, 2028. The Greeley, Colorado and Houston, Texas leases expire on August 19, 2019, June 30, 2019 and January 31, 2022, respectively. Total rental commitments under non-cancelable leases for office space were $35.7 million at December 31, 2017.

(2)As of December 31, 2017, we were subject to commitments on three drilling rigs. The three drilling rigs are under contract and are set to expire on February 15, 2018, August 21, 2018 and November 23, 2018.
(3)As of December 31, 2017, our oil marketer is subject to a firm transportation agreement that commenced in November 2016 and has a ten-year term with a monthly minimum delivery commitment of 45,000 Bbl/d in year one, 55,800 Bbl/d in year two, 61,800 Bbl/d in years three through seven and 58,000 Bbl/d in years eight through ten. In May 2017, we amended our agreement with our oil marketer that requires us to sell all of our crude oil from an area of mutual interest in exchange for a make-whole provision that allows us to satisfy any minimum volume commitment deficiencies incurred by our oil marketer with future barrels of crude oil in excess of their minimum volume commitment through October 31, 2018. In December 2017, we extended the term of this agreement through October 31, 2019 and posted a letter of credit in the amount of $35.0 million. We evaluate our contracts for loss contingencies and accrue for such losses, if the loss can be reasonably estimated and deemed probable. We also have one long-term crude oil gathering commitment with an unconsolidated subsidiary, in which we have a minority ownership interest. It has a term of ten years with a minimum volume commitment of an average 9,167 Bbl/d in year one, 17,967 Bbl/d in year two, 18,800 Bbl/d for years three through five and 10,000 Bbl/d for years six through ten. The remaining aggregate amount of estimated payments under these agreements is approximately $927.3 million.
(4)In collaboration with several other producers and a midstream provider, on December 15, 2016 and August 7, 2017, we agreed to participate in expansions of natural gas gathering and processing capacity in the DJ Basin. The plan includes two new processing plants as well as the expansion of related gathering systems, which are currently expected to be completed by mid-2018 and mid-2019, respectively, although the exact start-up dates are undetermined at this time. Our share of these commitments will require 51.5 MMcf and 20.6 MMcf per day, respectively, to be delivered after the plants' in-service dates for a period of seven years thereafter. We may be required to pay a shortfall fee for any volumes under these commitments. These contractual obligations can be reduced by our proportionate share of the collective volumes delivered to the plants by other third party incremental volumes available to the midstream provider at the new facilities that are in excess of the total commitments. We are also required for the first three years of each contract to guarantee a certain target profit margin on these volumes sold. Under its current drilling plans, we expect to meet these volume commitments and they have therefore not been reflected in the table above.
(5)Calculated based on balance of $90.0 million outstanding borrowings under our revolving credit facility as of December 31, 2017 and paid during the first quarter of 2018 and assumes no borrowings until the maturity date of the notes. Interest on our revolving credit facility is payable at one of the following two variable rates as selected by us: a base rate based on the Prime Rate or the Eurodollar rate based in LIBOR. Either rate is adjusted upward by an applicable margin, based on the utilization percentage of the facility as outlined in the Pricing Grid. Additionally, our revolving credit facility provides for a commitment fee of 0.375% to 0.50%, depending on borrowing base usage.
(6)Calculated based on the December 31, 2017 outstanding aggregate principal amount on our 2021 Senior Notes of $550.0 million outstanding, at a fixed interest rate of 7.875%, and outstanding principal amount on our 2024 Senior Notes of $400.0 million outstanding, at a fixed rate of 7.375%. Interest is payable on our 2021 Senior Notes and 2024 Senior Notes on a semi-annual basis through the maturity dates of July 15, 2021 and May 15, 2024, respectively. The 2026 Senior Notes are not included in the table above, as they were issued in January 2018.
The above contractual obligations schedule does not include the Series A Preferred Stock, future anticipated settlement of derivative contracts or estimated amounts expected to be incurred in the future associated with the abandonment of our oil and gas properties, as we cannot determine with accuracy the timing of such payments. For further discussion regarding our derivative contracts and estimated future costs associated with the abandonment of our oil and gas properties, please refer to Note 9 — Equity, Note 6  — Commodity Derivative Instruments and Note 7  — Asset Retirement Obligations of our historical audited financial statements for the years ended December 31, 2017 and 2016. Additionally, for further information regarding our contractual obligations as of December 31, 2017, please refer to Note 13  — Commitments and Contingencies to our historical unaudited financial statements for the year ended December 31, 2017 and 2016.
As is customary in the oil and gas industry, we may at times have commitments in place to reserve or earn certain acreage positions or wells. If we do not meet such commitments, the acreage positions or wells may be lost or we may be required to pay damages if certain performance conditions are not met.
Off‑BalanceOff-Balance Sheet Arrangements
 
As of December 31, 2017,2020, we do not have material off-balance sheet arrangements, except for our agreement with our oil marketer. Our oil marketer is subject to a firm transportation agreement with a make-whole provision that allows us to satisfy any minimum volume commitment deficiencies incurred by our oil marketer with future barrels of crude oil in excess of their minimum volume commitment through October 31, 2019. Please see Note 13 - Commitments and Contingencies in Part II, Item 8 of this Annual Report.arrangements.
 

Impact of Inflation/Deflation and Pricing
 
All of our transactions are denominated in U.S. dollars. Typically, as prices for oil and natural gas increase, associated costs rise. Conversely, as prices for oil and natural gas decrease, costs decline. Cost declines tend to lag and may not adjust downward in proportion to decline commodity prices. Historically, field-level prices received for our oil and natural gas production have been volatile. During the year ended December 31, 2015,2020, commodity prices decreased while during the yearsfirst and second quarters and subsequently increased in the third and fourth quarters. During the year ended December 31, 2017 and 2016,2019, commodity prices increased.decreased during the first quarter, increased in the second quarter, and subsequently decreased in the third quarter and fourth quarter. Changes in commodity prices impact our revenues, estimates of reserves, assessments of any impairment of oil and natural gas properties, as well as values of properties being acquired or sold. Price changes have the potential to affect our ability to raise capital, borrow money, and retain personnel.


Critical Accounting Policies and Estimates
 
Use of Estimates in the Preparation of Financial Statements
 
The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of oil and gas reserves, assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant areas requiring the use of assumptions, judgments and estimates include include:

(1) oil and gas reserves;
(2) depreciation, depletion, amortization and accretion;
(3) cash flow estimates used in impairment testing of oil and gas propertiesproved and goodwill; (3) depreciation, depletion, amortization and accretion; unproved properties;
(4) asset retirement obligations; valuation of commodity derivative instruments;
(5) assigning fair value and allocating purchase price in connection with business combinations, including the determination of any resulting goodwill;
(6) asset retirement obligations;
(7) accrued revenue and related receivables; (7)

Although management believes these estimates are reasonable, actual results could differ from these estimates. We evaluate our estimates on an on-going basis and base our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances. Although actual results may differ from these estimates under different assumptions or conditions, we believe our estimates are reasonable.

Successful Efforts Method of Accounting
 
We follow the successful efforts method of accounting for oil and gas properties. Under this method of accounting, all property acquisition costs and development costs are capitalized when incurred and depleted on a units-of-production basis over the remaining life of proved reserves and proved developed reserves, respectively.
 
The costs of exploratory wells are initially capitalized pending a determination of whether proved reserves have been found. At the completion of drilling activities, the costs of exploratory wells remain capitalized if a determination is made that proved reserves have been found. If no proved reserves have been found, the costs of exploratory wells are charged to expense. In some cases, a determination of proved reserves cannot be made at the completion of drilling, requiring additional testing and evaluation of the wells. Cost incurred for exploratory wells that find reserves that cannot yet be classified as proved are capitalized if (a) the well has found a sufficient quantity of reserves to justify its completion as a producing well and (b) sufficient progress in assessing the reserves and the economic and operating viability of the project has been made. The status of suspended well costs is monitored continuously and reviewed quarterly. Due to the capital-intensive nature and the geographical characteristics of certain projects, it may take an extended period of time to evaluate the future potential of an exploration project and the economics associated with making a determination of its commercial viability.
 
Geological and geophysical costs are expensed as incurred. Costs of seismic studies that are utilized in development drilling within an area of proved reserves are capitalized as development costs. Amounts of seismic costs capitalized are based on only those blocks of data used in determining development well locations. To the extent that a seismic project covers areas of both developmental and exploratory drilling, those seismic costs are proportionately allocated between development costs and exploration expense.
 
We capitalize interest, if debt is outstanding, during drilling operations in our exploration and development activities.
 
Oil and Gas Reserves
 
Our estimates of proved reserves are based on the quantities of oil, natural gas and NGL, 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 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 that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. Our independent petroleum

engineers, Ryder Scott, prepare a reserve and economic evaluation of all of our properties on a well-by-well basis. The accuracy of reserve estimates is a function of the: 

quality and quantity of available data;
interpretation of that data;
accuracy of various mandated economic assumptions; and
judgment of the independent reserve engineer.
 
One of the most significant estimates we make is the estimate of oil, natural gas and NGL reserves. Oil, natural gas and NGL reserve estimates require significant judgments in the evaluation of all available geological, geophysical, engineering and economic data. The data for a given field may change substantially over time as a result of numerous factors including, but not limited to, additional development activity, production history, projected future production, economic assumptions relating to commodity prices, operating expenses, severance and other taxes, capital expenditures and remediation costs and these estimates are inherently uncertain. For example, if estimates of proved reserves decline, our DD&A rate will increase, resulting in a decrease in net income. A decline in estimates of proved reserves could also cause us to perform an impairment analysis to determine if the carrying amount of oil and gas properties exceeds fair value and could result in an impairment charge, which would reduce earnings. We cannot predict what reserve revisions may be required in future periods.
 
Ryder Scott estimated all of our proved reserve quantities as of December 31, 2017, 20162020 and 2015.2019. In connection with Ryder Scott performing their independent reserve estimations, we furnish them with the following information that they review: (1) technical support data, (2) technical analysis of geologic and engineering support information, (3) economic and production data and (4) our well ownership interests.
 
The following table presents information about proved reserve changes from period to period due to items we do not control, such as price, and from changes due to production history and well performance. These changes do not require a capital expenditure on our part, but may have resulted from capital expenditures we incurred to develop other estimated proved reserves.

The recent significant declineDeclines in oil, natural gas and NGL prices increasesincrease the uncertainty as to the impact of commodity prices on our estimated proved reserves. We are unable to predict future commodity prices with any greater precision than the futures market. A prolonged period of depressed commodity prices may have a significant impact on the value and volumetric quantities of our proved reserve portfolio, assuming no other changes to our development plans or costs.
 
Depreciation, Depletion, Amortization and Accretion.Accretion
 
Our DD&A rate is dependent upon our estimates of total proved and proved developed reserves, which incorporate various assumptions and future projections. If our estimates of total proved or proved developed reserves decline, the rate at which we record DD&A expense increases, which in turn reduces our net income. Such a decline in reserves may result from lower commodity prices or other changes to reserve estimates, as discussed above, and we are unable to predict changes in reserve quantity estimates as such quantities are dependent on the success of our exploration and development program, as well as future economic conditions.
 
Impairment of Proved Oil and Gas Properties
 
Proved oil and gas properties are reviewed for impairment annually or when events and circumstances indicate a possible decline in the recoverability of the carrying amount of such property. We estimate the expected future cash flows of itsour oil and gas properties and compares these undiscounted cash flows to the carrying amount of the oil and gas properties to determine if the carrying amount is recoverable. If the carrying amount exceeds the estimated undiscounted future cash flows, we will write down the carrying amount of the oil and gas properties to fair value. The factors used to determine fair value include, but are not limited to, estimates of reserves, future commodity prices, future production estimates, estimated future

capital expenditures, estimated future operating costs, and discount rates commensurate with the risk associated with realizing the projected cash flows. Impairment expense for proved oil and gas properties is reported in impairment of long lived assets and goodwill in the consolidated statements of operations, which increases accumulated depletion, depreciation and amortization.
 
For the year endedFuture commodity pricing for oil is based on five-year West Texas Intermediate strip prices, which decreased 14.0% from an average of $53.65/Bbl at December 31, 2017, we recognized no impairment expense on proved oil and gas properties. For the years ended2019 to an average of $46.14/Bbl at December 31, 2016 and 2015, we recognized $22.5 million and $9.5 million, respectively, in impairment expense2020. Future commodity pricing for natural gas is based on proved oil and gas properties in our northern field. The future undiscounted cash flows did not exceed its carrying amount associated with its proved oil and gas properties in its northern field and it was determined that the proved oil and gas properties had no remaining fair value. Therefore, the full net book valuefive-year Henry Hub strip prices, which increased 4.9% from an average of these proved oil and gas properties were impaired$2.42/MMBtu at June 30, 2016 and 2015. In December 2015, we sold proved oil and gas properties for proceeds of $4.7 million. As a result, these assets were fair valued on the date of the transaction in accordance with ASC 360, Property, Plant and Equipment. The net book value of these assets exceeded the fair value by $2.7 million, which we recognized as impairment expense. We recognized $12.2 million in impairment expense that was attributable to proved oil and gas properties for the year ended December 31, 2015.2019 to an average of $2.54/MMBtu at December 31, 2020. Future commodity pricing for NGLs is based on five-year WTI strip prices, which decreased 10.7% from an average of $14.40/Bbl at December 31, 2019 to an average of $12.85/Bbl at December 31, 2020.

Our impairment analysesanalysis requires us to apply judgment in identifying impairment indicators and estimating future cash flows of our oil and gas properties. If actual results are not consistent with our assumptions and estimates or our assumptions and estimates change due to new information, we may be exposed to an impairment charge.

For the year ended December 31, 2020, our impairment expense related to oil and gas properties was $197.9 million. We recognized $3.6 million related to impairment of the proved oil and gas properties in our northern field and $194.3 million related to assets in one of our Core DJ Basin fields, as the fields’ fair values did not exceed the carrying amounts associated with our proved oil and gas properties. For the year ended December 31, 2019, our impairment expense was $1.3 billion. We recognized $14.5 million related to impairment of the proved oil and gas properties in our northern field and $1.3 billion related to assets in one of our Core DJ Basin fields as the fields’ fair values did not exceed the carrying amounts associated with our proved oil and gas properties.

Forward commodity prices and estimates of future production also play a significant role in determining impairment of proved oil and gas properties. As a result of lower commodity prices and their impact on our estimated future cash flows, we have continuedwill continue to review our proved oil and gas properties for impairment. After our fourth quarter 2020 impairment charges in two of our Core DJ Basin fields at December 31, 2020, the carrying value of our oil and gas properties exceeded our expected undiscounted future cash flows for proved and risk-adjusted probable and possible reserves by approximately $56.8 million and $340.3 million, in each field. After our fourth quarter 2019 impairment charges in two of our Core DJ Basin fields at
73

December 31, 2019, the carrying value of our oil and gas properties exceeded our expected undiscounted future cash flows for proved and risk-adjusted probable and possible reserves by approximately $33.8 million and $1.2 billion, in each field. At December 31, 2017,2018, our expected undiscounted future cash flows exceeded the carrying value of our proved oil and gas properties by approximately $1.6$0.8 billion, or 68%30%. At December 31, 2016, our expected undiscounted future cash flows exceeded the carrying value of our proved oil and gas properties by approximately $1.7 billion, or 108%. The key assumptions used to determine the undiscounted future cash flows include estimates of future production, future commodity pricing, differentials, net estimated operating costs, anticipated capital expenditures and new wells on production. Future commodity pricing for oil and NGL is based on five-year West Texas Intermediate strip prices, which decreased 3% from an average of $56.23/Bbl at December 31, 2016 to an average of $54.66/Bbl at December 31, 2017, and on five-year Henry Hub strip prices, which increased 1.9% from an average of $3.08/MMBtu at December 31, 2016 to an average of $3.14/MMBtu at December 31, 2017.
 
ImpairmentAbandonment of Unproved Oil and Gas Properties
 
Unproved oil and gas properties consist of costs to acquire unevaluated leases as well as costs to acquire unproved reserves. We evaluate significant unproved oil and gas properties for impairment based on remaining lease term, drilling results, reservoir performance, seismic interpretation or future plans to develop acreage. When successful wells are drilled on undeveloped leaseholds, unproved property costs are reclassified to proved properties and depleted on a unit-of-production basis. Impairment expense and lease extension payments for unproved properties is reported in exploration and abandonment expenses in the consolidated statements of operations. As a result of the abandonment and impairment of unproved properties, we recognized $15.8 million, $22.3$253.1 million and $16.4$73.7 million in impairmentabandonment expense for the years ended December 31, 2017, 20162020 and 2015,2019, respectively. To the extent we do not elect to renew current leases, we expect further abandonment charges in 2021.
Goodwill and Other Intangible Assets
We apply the provisions of ASC 350, Intangibles-Goodwill and Other. Goodwill represents the excess of the purchase price over the estimated value of the net assets acquired in business combinations. We test goodwill for impairment annually on September 30, or whenever other circumstances or events indicate that the carrying amount of goodwill may not be recoverable. The goodwill test is performed at the reporting unit level, which represents our oil and gas operations in its core DJ Basin field. If indicators of impairment are determined to exist, an impairment charge is recognized if the carrying value of goodwill exceeds its implied fair value. Any sharp prolonged decreases in the prices of oil and natural gas as well as continued declines in the quoted market price of our common shares could change the estimates of the fair value of the reporting unit and could result in an impairment charge. We performed an assessment as of September 30, 2017, which concluded the fair value of the reporting unit was greater than its carrying amount.

We performed a qualitative assessment as of December 31, 2017 and 2016, which concluded the fair value of the reporting unit was more-likely-than-not greater than its carrying amount.
Costs relating to the acquisition of internal-use software licenses are capitalized when incurred and amortized over the estimated useful life of the license.


Commodity Derivative Instruments
 
We have entered into commodity derivative instruments as described below. We have utilizedutilizing swaps put options, and call options to reduce the effect of price changes on a portion of our future oil and natural gas production. A swap has an established fixed price. When the settlement price is below the fixed price, the counterparty pays us an amount equal to the difference between the settlement price and the fixed price multiplied by the hedged contract volume. When the settlement price is above the fixed price, we pay our counterparty an amount equal to the difference between the settlement price and the fixed price multiplied by the hedged contract volume. A put option has an established floor price. The buyer of the put option pays the sellerFor a premium to enter into the put option. When the settlement price is below the floor price, the seller pays the buyer an amount equal to the difference between the settlement price and the strike price multiplied by the hedged contract volume. When the settlement price is above the floor price, the put option expires worthless. Somedescription of our purchased put options have deferred premiums. For the deferred premium puts,derivative instruments that we agree to payutilize and a premium to the counterparty at the time of settlement.
A call option has an established ceiling price. The buyer of the call option pays the seller a premium to enter into the call option. When the settlement price is above the ceiling price, the seller pays the buyer an amount equal to the difference between the settlement price and the strike price multiplied by the hedged contract volume. When the settlement price is below the ceiling price, the call option expires worthless.
We combine swaps, purchased put options, sold put options, and sold call options in order to achieve various hedging strategies. Some examplessummary of our hedging strategies are collars which include purchased put options and sold call options, three-way collars which include purchased put options, sold put options, and sold call options, and enhanced swaps, which include either sold put options or sold call options with the associated premiums rolled into an enhanced fixed price swap.
The objective of our use ofopen commodity derivative instruments is to achieve more predictable cash flows contracts as of December 31, 2020, please see Note 9 — Commodity Derivative Instruments in an environmentPart II, Item 8. Financial Statements and Supplementary Data of volatile oil and gas prices and to manage its exposure to commodity price risk. While the use of these commodity derivative instruments limits the downside risk of adverse price movements, such use may also limit our ability to benefit from favorable price movements. We may, from time to time, add incremental derivatives to hedge additional production, restructure existing derivative contracts or enter into new transactions to modify the terms of current contracts in order to realize the current value of our existing positions. We do not enter into derivative contracts for speculative purposes.this Annual Report.
 
The commodity derivative instruments are measured at fair value and are included in the accompanying consolidated balance sheets as commodity derivative assets.assets or liabilities. We have not designated any of the derivative contracts as fair value or cash flow hedges. Therefore, we do not apply hedge accounting to the commodity derivative instruments. Net gains and losses on commodity derivative instruments are recorded based on the changes in the fair values of the derivative instruments. Net gains and losses on commodity derivative instruments are recorded in the commodity derivative gain (loss) line on the consolidated statements of operations. Our cash flow is only impacted when the actual settlements under the commodity derivative contracts result in making or receiving a payment to or from the counterparty. These settlements under the commodity derivative contracts are reflected as operating activities in our consolidated statements of cash flows.
 
Our valuation estimate takes into consideration the counterparties’ credit worthiness, our credit worthiness, and the time value of money. The consideration of the factors resultresults in an estimated exit-price for each derivative asset or liability under a market place participant’s view. Management believesWe believe that this approach provides a reasonable, non-biased, verifiable, and consistent methodology for valuing commodity derivative instruments. Please see “—How We Evaluate Our Operations—Derivative Arrangements.”


Accounting for Business Combinations

We account for all of our business combinations using the purchaseacquisition method, which is the only method permitted under FASB ASC 805,, Business Combinations,, and involves the use of significant judgment. In connection with a business combination, the acquiring company must allocate the cost of the acquisition to assets acquired and liabilities assumed based on fair values as of the acquisition date. Any excess or shortage of amounts assigned to assets and liabilities over or under the purchase price is recorded as a gain on bargain purchase or goodwill. The amount of goodwill or gain on bargain purchase recorded in any particular business combination can vary significantly depending upon the values attributed to assets acquired and liabilities assumed.

In estimating the fair values of assets acquired and liabilities assumed in a business combination, we make various assumptions. The most significant assumptions relate to the estimated fair values assigned to proved and unproved oil and gas

properties. If sufficient market data is not available regarding the fair values of proved and unproved properties, we must prepare estimates. To estimate the fair values of these properties, we prepare estimates of gas, oil and NGL reserves. We estimate future prices to apply to the estimated reserves quantities acquired and estimate future operating and development costs to arrive at estimates of future net cash flows. For estimated proved reserves, the future net cash flows are discounted using a market-based weighted average cost of capital rate determined appropriate at the time of the acquisition. The market-based weighted average cost of capital rate is subjected to additional project-specific risking factors. To compensate for the inherent risk of estimating and valuing unproved reserves, when a discounted cash flow model is used, the discounted future net cash flows of probable and possible reserves are reduced by additional risk factors. In some instances, market comparable information of recent transactions is used to estimate fair value of unproved acreage.
74


Estimated fair values assigned to assets acquired can have a significant effect on results of operations in the future. A higher fair value assigned to a property results in higher DD&A expense, which results in lower net earnings. Fair values are based on estimates of future commodity prices, reserves quantities, operating expenses and development costs. This increases the likelihood of impairment if future commodity prices or reserves quantities are lower than those originally used to determine fair value, or if future operating expenses or development costs are higher than those originally used to determine fair value. Impairment would have no effect on cash flows but would result in a decrease in net income for the period in which the impairment is recorded.

Asset Retirement Obligations
 
Our asset retirement obligations (“ARO”) consist of estimated future costs associated with the plugging and abandonment of oil, natural gas and NGL wells, removal of equipment and facilities from leased acreage and land restoration in accordance with applicable local, state and federal laws, and applicable lease terms. The fair value of an ARO liability is required to be recognized in the period in which it is incurred, with the associated asset retirement cost capitalized as part of the carrying cost of the oil and gas asset. The recognition of an ARO requires that management make numerous assumptions regarding such factors as the estimated probabilities, amounts and timing of settlements; the credit-adjusted risk-free discount rate to be used; and inflation rates. In periods subsequent to the initial measurement of the ARO, we must recognize period-to-period changes in the liability resulting from the passage of time and revisions to either the timing or the amount of the original estimate of undiscounted cash flows. Increases in the ARO liability due to the passage of time impact net income as accretion expense. The related capitalized cost, including revisions thereto, is charged to expense through DD&A over the life of the oil and gas property.
 
Revenue Recognition
 
RevenuesRevenue from the sale of oil, natural gas and NGL areNGLs is recognized whenin accordance with ASC 606 - Revenue from Contracts with Customers five-step revenue recognition model to depict the product is delivered at a fixedtransfer of goods or determinable price, title has transferred, and collectability is reasonably assured and evidenced by a contract. Weservices to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. To account for producer imbalances, we recognize revenues from the saleon all sales of oil, natural gas and NGL usingNGLs to third party customers regardless of their ownership percentage and adjust the sales method of accounting, wherebyunderlifter or overlifter’s claim on the asset’s remaining reserves. In other words, revenue is recorded based on our share of volume sold, regardless of whether we have taken our proportional share of volume produced. A receivable or liability is recognized only to the extent that we have an imbalance on a specific property greater than the expected remaining proved reserves. We receive payment one to three months after delivery. At the end of each month, we estimate the amount of production delivered to purchasers and the price we will receive. Variances between our estimates and the actual amounts received are recorded in the month payment is received. A 10% change in our revenue accrual would have impacted total operating revenues by approximately $9.3$6.3 million and $3.4$10.5 million for the years ended December 31, 20172020 and 2016,2019, respectively.


Unit and Stock‑BasedStock-Based Payments
 
The CompanyWe granted awards under the 2016 LTIP and its predecessor, Holdings, has granted restricted unit awards (“RUAs”)2021 LTIP (as defined in Note 14 — Stock-Based Compensation in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report) to certain directors, officers and employees, and nonemployee consultants of the Company,including stock options, restricted stock units, (“RSUs”), stock option awards and performance stock awards, ("PSAs) to certain employees of the Company,performance stock units, performance cash awards and cash awards which therefore required the Companyus to recognize the expense in itsour consolidated financial statements.


All unit and stock‑basedstock-based payments to employees are measured at fair value on the grant date and expensed over the relevant service period. Unit‑based payments to nonemployees are measured at fair value at each financial reporting date and expensed over the period of performance, such that aggregate expense recognized is equal to the fair value of the restricted units on the date performance is completed. The fair value of stock option awards is determined by using the Black-Scholes option pricing model. The fair value of the PSAs was measured at the grant date with a stochastic process method using a Monte Carlo simulation. All unit and stock‑basedstock-based payment expense is recognized using the straight‑linestraight-line method and is included within general and administrative expenses in the consolidated statements of operations and unit and stock-based compensation

in the consolidated statements of cash flows. Forfeitures are recorded as they occur. Please refer to Note 1114 — UnitStock-Based Compensation in Part II, Item 8. Financial Statements and Stock‑Based CompensationSupplementary Data of this Annual Report for additional discussion on unit and stock‑basedstock-based payments.

Income Taxes
 
We account for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis, and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are calculated by applying existing tax laws and the rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The tax returns and the amount of taxable income or loss are subject to examination by deferralfederal and state taxing authorities.

We periodically assess whether it is more likely than not that itthe Company will generate sufficient taxable income to realize its deferred income tax assets, including net operating losses.NOLs. In making this determination, we consider all the available positive and negative evidence and makesmake certain assumptions. We consider, among other things, our deferred tax liabilities, the overall business environment, its historical earnings and losses, current industry trends, and its outlook for future years. We believe it is more likely than not that certain net operating losses canthe benefit from NOL carryforwards will not be carried forward and utilized.fully realized. In recognition of this risk, we have provided a valuation allowance on the deferred tax assets.

We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. We do not currently have uncertain tax positions.


On December 22, 2017, United States legislation referredThe CARES Act provides relief to corporate taxpayers by permitting a five year carryback of 2018-2020 NOLs, removing the 80% limitation on the carryback of those NOLs, increasing the Section 163(j) 30% limitation on interest expense deductibility to 50% of adjusted taxable income for 2019 and 2020 as the "Tax Cutswell as allowing 2019 adjusted taxable income to be utilized for 2020 limitation purposes, and Jobs Act" (the "TCJA") was signed into law. Many of the provisions of the TCJA are effectiveaccelerating refunds for taxable years beginning after December 31, 2017. The TCJA includes changes to the Internal Revenue Code of 1986 (as amended, the "Code"). The most significant change included in the TCJA isminimum tax credit carryforwards, along with a reduction in the corporate federal income tax rate from 35% to 21%. Asfew other provisions.

Bankruptcy Proceedings

Effective June 14, 2020, as a result of the enactment datefiling of December 22, 2017,the Chapter 11 Cases, we began accounting and reporting according to ASC Topic 852 — Reorganizations in preparing our consolidated financial statements. ASC 852 requires that the financial statements, for periods subsequent to the Chapter 11 Cases, distinguish transactions and events that are required to remeasuredirectly associated with the deferred tax assetsreorganization from the ongoing operations of the business. Accordingly, certain professional fees, damages from rejected and liabilities at the rate in which they are expected to reverse. This re-measurement of deferred tax assets and liabilities will require us to analyze and record a one-time adjustment to reduce the overall deferred tax liabilitysettled contracts incurred in the bankruptcy proceedings, including losses related to executory contracts that were approved for rejection by the Bankruptcy Court, and unamortized deferred financing costs associated with debt classified as liabilities subject to compromise, are recorded in reorganization items, net on our accompanying consolidated statements of operations. In addition, pre-petition obligations that may be impacted by the bankruptcy reorganization process have been classified on our consolidated balance sheets and affect a corresponding income tax benefit in the consolidated statementsas of operations for the year ended December 31, 2017.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
We are exposed to market risk, including the effects of adverse changes in commodity prices and interest rates as described below. The primary objective of the following information is to provide quantitative and qualitative information about our potential exposure to market risks. The term “market risk” refers to the risk of loss arising from adverse changes in oil, natural gas and NGL prices and interest rates. The disclosures are not meant to be precise indicators of expected future losses, but rather indicators of reasonably possible losses. All of our market risk sensitive instruments were entered into for purposes other than speculative trading.
Commodity Price Risk
Our major market risk exposure is in the pricing that we receive for our oil, natural gas and NGL production. Pricing for oil, natural gas and NGL has been volatile and unpredictable for several years, and this volatility is expected to continue in the future. The prices we receive for our oil, natural gas and NGL production depend on many factors outside of our control, such as the strength of the global economy and global supply and demand for the commodities we produce.
To reduce the impact of fluctuations in oil prices on our revenues, we have periodically entered into commodity derivative contracts with respect to certain of our oil and natural gas production through various transactions that limit the downside of future prices received. We plan to continue our practice of entering into such transactions to reduce the impact of commodity price volatility on our cash flow from operations. Future transactions may include price swaps whereby we will receive a fixed price for our production and pay a variable market price to the contract counterparty. Additionally, we may enter into collars, whereby we receive the excess, if any, of the fixed floor over the floating rate or pay the excess, if any, of the floating rate over the fixed ceiling price. These hedging activities are intended to support oil prices at targeted levels and to manage our exposure to oil price fluctuations.

AsTable of December 31, 2017, the fair market value of our oil derivative contracts was a net liability of $92.3 million. Based on our open oil derivative positions at December 31, 2017, a 10% increase in the NYMEX WTI price would increase our net oil derivative liability by approximately $90.9 million, while a 10% decrease in the NYMEX WTI price would decrease our net oil derivative liability by approximately $81.8 million. As of December 31, 2017, the fair market value of our natural gas derivative contracts was a net asset of $11.7 million. Based upon our open commodity derivative positions at December 31, 2017, a 10% increase in the NYMEX Henry Hub price would decrease our net natural gas derivative asset by approximately $11.8 million, while a 10% decrease in the NYMEX Henry Hub price would increase our net natural gas derivate asset by approximately $11.8 million. Please see “—Derivative Arrangements.”Contents
Counterparty and Customer Credit Risk
Our cash and cash equivalents are exposed to concentrations of credit risk. We manage and control this risk by investing these funds with major financial institutions. We often have balances in excess of the federally insured limits.
We sell oil, natural gas and NGL to various types of customers, including oil marketers, pipelines and refineries. Credit is extended based on an evaluation of the customer’s financial conditions and historical payment record. The future availability of a ready market for oil, natural gas and NGL depends on numerous factors outside of our control, none of which can be predicted with certainty. For the year ended December 31, 2017, we had certain major customers that exceeded 10% of total oil, natural gas and NGL revenues. We do not believe the loss of any single purchaser would materially impact its operating results because oil, natural gas and NGL are fungible products with well‑established markets and numerous purchasers.
At December 31, 2017, we had commodity derivative contracts with seven counterparties, all of whom are lenders under our credit agreement. We do not require collateral or other security from counterparties to support derivative instruments; however, to minimize the credit risk in derivative instruments, it is our policy to enter into derivative contracts only with counterparties that are creditworthy financial institutions deemed by management as competent and competitive market‑makers. Additionally, we use master netting agreements to minimize credit‑risk exposure. The creditworthiness of our counterparties is subject to periodic review. Three of the seven counterparties to the derivative instruments are highly rated entities with corporate ratings at A3 classifications or above by Moody’s. Three additional counterparties have a corporate rating of Baa1 by Moody’s. One counterparty is a private entity and has a corporate rating of NAIC-2 by the National Association of Insurance Commissioners. For the years ended December 31, 2017, 2016 and 2015, we did not incur any losses with respect to counterparty contracts. None of our existing derivative instrument contracts contains credit‑risk related contingent features.
Interest Rate Risk
At December 31, 2017, we had $90.0 million of variable‑rate debt outstanding. The impact on interest expense of a 1% increase or decrease in the average interest rate would be approximately $0.9 million. We may begin entering into interest rate swap arrangements on a portion of our outstanding debt to mitigate the risk of fluctuations in LIBOR if we have variable-rate debt outstanding in the future.

DefinitionCritical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and Limitationsthat (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of Internal Control over Financial Reportingcritical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.


A company’s internal control overThe Impact of Proved Oil, Natural Gas, and Natural Gas Liquids (NGL) Reserves on Net Oil and Gas Properties

As described in Note 3 to the consolidated financial reportingstatements, the Company’s consolidated proved oil and gas properties balance was $4,743.5 million as of December 31, 2020, and depletion, depreciation, amortization and accretion expense was $332.3 million for the year ended December 31, 2020. As disclosed by management, estimates of proved reserves are based on the quantities of oil, natural gas and NGL, 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 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 that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The accuracy of reserve estimates is a process designedfunction of the quality and quantity of available data; interpretation of that data; accuracy of various mandated economic assumptions; and judgment of the independent reserve engineer. The Company follows the successful efforts method of accounting for oil and gas properties. Under this method of accounting, all property acquisition costs and development costs are capitalized when incurred and depleted on a units-of-production basis over the remaining life of proved reserves and proved developed reserves, respectively. Oil, natural gas and NGL reserve estimates require significant judgments in the evaluation of all available geological, geophysical, engineering and economic data. The data for a given field may change substantially over time as a result of numerous factors including, but not limited to, provide reasonable assurance regardingadditional development activity, production history, projected future production, economic assumptions relating to commodity prices, operating expenses, severance and other taxes, capital expenditures and remediation costs and these estimates are inherently uncertain. Independent petroleum engineers prepare a reserve and economic evaluation of all of the reliabilityCompany’s properties on a well-by-well basis.

78

The principal considerations for our determination that performing procedures relating to the impact of proved oil, natural gas, and NGL reserves on net oil and gas properties is a critical audit matter are (i) the significant judgment by management, including the use of specialists, when developing the estimates of proved oil, natural gas and NGL reserves, which in turn led to (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating audit evidence related to the data, methods, and assumptions used by management and its specialists in developing the estimates of proved oil, natural gas, and NGL reserves and the preparationassumptions applied to the data related to the projected future production, commodity prices, future development costs, and operating expenses.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. The work of management’s specialists was used in performing the procedures to evaluate the reasonableness of proved oil, natural gas, and NGL reserves. As a basis for using this work, the specialists’ qualifications were understood and the Company’s relationship with the specialists was assessed. The procedures performed also included evaluation of the methods and assumptions used by the specialists, tests of the data used by the specialists, and an evaluation of the specialists’ findings. These procedures also included, among others, testing the completeness and accuracy of data related to commodity prices, future development costs, and operating expenses. Additionally, these procedures included evaluating whether the assumptions applied to the data related to projected future production, commodity prices, future development costs, and operating costs were reasonable considering the past performance of the Company.

Impairment Assessments of Certain Net Oil and Gas Properties

As described in Notes 2, 3, and 11 to the consolidated financial statements, as of December 31, 2020, the Company’s proved crude oil and gas properties were approximately $4,743.5 million, which includes impairment expense related to oil and gas properties of $197.9 million for external purposesthe year then ended. Proved oil and gas properties are reviewed for impairment annually or when events and circumstances indicate a possible decline in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policiesthe recoverability of the carrying amount of such property. For all of its fields, the Company estimates the expected future cash flows of its oil and procedures that (i) pertaingas properties and compares these undiscounted cash flows to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositionscarrying amount of the assetsoil and gas properties to determine if the carrying amount is recoverable. If the carrying amount exceeds the estimated undiscounted future cash flows, the Company will write down the carrying amount of the company;oil and gas properties to fair value. To determine fair value, the Company uses an income approach analysis based on the net discounted future cash flows of proved property. The Company calculates the estimated fair values of its proved property oil and gas assets using a discounted future cash flow model. Significant inputs associated with the calculation of discounted future net cash flows include estimates of (i) recoverable reserves, (ii) provide reasonable assurance that transactions are recorded as necessaryfuture operating and development costs, (iii) future commodity prices, and (iv) a market-based weighted average cost of capital. The Company recognized $3.6 million related to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expendituresimpairment of the company are being made onlyproved oil and gas properties in accordance with authorizations of managementthe Company’s northern field and directors$194.3 million related to assets in one of the company;Company’s Core DJ Basin fields, as the fields’ fair values did not exceed the carrying amounts associated with the proved oil and gas properties.

The principal considerations for our determination that performing procedures relating to the impairment assessments of certain net oil and gas properties is a critical audit matter are (i) the significant judgment by management when developing the undiscounted and net discounted future cash flow analyses for the impairment assessments, (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s assumptions related to recoverable reserves, future operating and development costs, future commodity prices, and the market-based weighted average cost of capital, and (iii) provide reasonable assurance regarding prevention or timely detectionthe audit effort involved the use of unauthorized acquisition, use, or dispositionprofessionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included, among others (i) testing management’s process for developing the undiscounted and net discounted future cash flow analyses; (ii) evaluating the appropriateness of the company’s assets that could haveundiscounted and net discounted cash flow analyses; (iii) testing the completeness and accuracy of the underlying data used in the models; and (iv) evaluating the significant assumptions used by management related to recoverable reserves, future operating and development costs, future commodity prices, and the market-based weighted average cost of capital. Evaluating the reasonableness of management’s assumptions related to (i) future operating and development costs involved consideration of the past and anticipated performance of the Company and (ii) future commodity prices involved consideration of observable market data. The work of specialists was used in performing the procedures to evaluate the reasonableness of the recoverable reserves, as stated in the Critical Audit Matter titled “The Impact of Proved Oil, Natural Gas, and Natural Gas Liquids (NGL) Reserves on Net Oil and Gas Properties”. As a material effect onbasis for using this work, the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of anyspecialists’ qualifications were understood and the Company’s relationship with the specialists was assessed. The procedures performed also included evaluation of effectivenessthe methods and assumptions used by the specialists, tests of the data used by the specialists and an evaluation of the specialists’ findings. Professionals with specialized skill and knowledge were used to future periods are subject toassist in evaluating the risk that controls may become inadequate becausereasonableness of changes in conditions, or that the degreemarket-based weighted average cost of compliance with the policies or procedures may deteriorate.capital.

As previously disclosed, on June 14, 2020 (the “Petition Date”), Extraction and its wholly owned subsidiaries (collectively, the “Debtors”), filed voluntary petitions for relief under chapter 11 (“Chapter 11”) of title 11 of the United States Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the period January 1, 2016 through October 12, 2016 and forDistrict of Delaware (the “Bankruptcy Court”). The Debtors’ Chapter 11 cases (the “Chapter 11 Cases”) were jointly administered under the year ended December 31, 2015 are based on the financial statements of the Company's accounting predecessor,caption In re Extraction Oil & Gas Holdings, LLC ("Holdings"Gas., et al. Case No. 20-11548 (CSS).

While in Chapter 11, the Debtors continued to operate their businesses and manage their properties as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.

The commencement of a voluntary proceeding in bankruptcy constituted an immediate event of default under the Predecessor Credit Agreement (as defined in Note 8—Long-Term Debt) and the indentures governing the Company’s Senior Notes (as defined in Note 2—Basis of Presentation and Significant Accounting Policies), resulting in the automatic and immediate acceleration of all of the Company’s debt outstanding under the Predecessor Credit Agreement and Senior Notes. Accordingly, the Company has classified its outstanding Senior Notes debt as liabilities subject to compromise on its consolidated balance sheet as of December 31, 2020. The Prior Credit Facility (as defined in Note 8—Long-Term Debt) was not classified as liabilities subject to compromise because it was fully secured and unimpaired before being paid off as part of the Company’s emergence from bankruptcy described below. Please refer to Note 5—Liabilities Subject to Compromise for more information. Pursuant to the Bankruptcy Code and as described in Note 8—Long-TermDebt, the filing of the Chapter 11 Cases automatically stayed most actions against the Debtors, including most actions to collect indebtedness incurred prior to the corporate reorganization (the "Corporate Reorganization"), pursuantPetition Date or to which, in connection withexercise control over the initial public offeringDebtors’ property.

Plan, Disclosure Statement, and Backstop Commitment Agreement

On July 30, 2020, the Debtors filed a proposed Plan of Reorganization (as amended, modified, or supplemented from time to time, the “Plan”) and related Disclosure Statement (as amended or modified, the “Disclosure Statement”) describing the Plan and the solicitation of votes to approve the same from certain of the Company (the "Offering" or "IPO"), (i)Debtors’ creditors with respect to the Chapter 11 Cases. Subsequently on October 22, 2020 and November 5, 2020, the Debtors filed first and second amendments, respectively, to the Disclosure Statement. The hearing to consider approval of the Disclosure Statement was held on November 6, 2020. On November 6, 2020, the Bankruptcy Court approved the adequacy of the Disclosure Statement and the Debtors commenced a solicitation process to receive votes on the Plan. Pursuant to the terms of the Plan and as described in the Disclosure Statement, the Debtors also commenced a rights offering (the “Equity Rights Offering”), which was backstopped by certain holders of the Senior Notes. On November 6, 2020, the Bankruptcy Court approved the Backstop Commitment Agreement (the “Backstop Commitment Agreement”), which provided a commitment of $200 million. The hearing on the confirmation of the Plan was held on December 23, 2020, in which the Plan was approved.

Emergence from Chapter 11 2016, a former subsidiaryBankruptcy

On December 23, 2020, the Company filed the Sixth Amended Joint Plan of Reorganization of Extraction Oil & Gas, Holdings, LLC, Extraction Oil & Gas, LLC, convertedInc. pursuant to Chapter 11 of the Bankruptcy Code. Also on December 23, 2020, the Bankruptcy Court entered an order (the “Confirmation Order”) confirming the Plan. The Plan is attached to the Confirmation Order as Exhibit A. The sixth-amended Plan and the Confirmation Order were previously filed as Exhibits 2.1 and 99.1 to the Company’s Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission on December 30, 2020. On January 20, 2021 (the “Emergence Date”) the Plan became effective in accordance with its terms and the Company emerged from the Chapter 11 Cases. On the Emergence Date and pursuant to the Plan:

The Company amended and restated its certificate of incorporation and bylaws;

The Company constituted a new board of directors;

The Company appointed a new Chief Executive Officer, President and Chief Operating Officer, and Chief Financial Officer;

The Company issued new common stock in the Successor Company (the “New Common Stock”) and New Warrants (as defined in Note 12—Equity):

2,832,833 shares of New Common Stock pro rata to holders of the 2024 Notes;

4,854,017 shares of New Common Stock pro rata to holders of the 2026 Notes;

179,472 shares of New Common Stock, 1,454,832 Tranche A Warrants to purchase 1,454,832 shares of New Common Stock and 727,420 Tranche B Warrants to purchase 727,420 shares of New Common Stock pro rata to holders of the Predecessor Company’s Series A Preferred Stock (the “Predecessor Preferred Stock”) outstanding prior to the Emergence Date;

179,496 shares of New Common Stock, 1,454,854 Tranche A Warrants to purchase 1,454,854 shares of New Common Stock and 727,443 Tranche B Warrants to purchase 727,443 shares of New Common Stock pro rata to holders of the Predecessor Company’s existing common stock (the “Predecessor Common Stock”) outstanding prior to the Emergence Date;

1,169,322 shares of New Common Stock to commitment parties under the Backstop Commitment Agreement in respect of the commitment premium due thereunder;

844,760 shares of New Common Stock to the commitment parties under the Backstop Commitment Agreement in connection with their backstop obligation thereunder to purchase unsubscribed shares of New Common Stock;

11,478,670 shares of New Common Stock were issued to participants in the Equity Rights Offering extended by the Company to the applicable classes under the Plan (including to the commitment parties party to the Backstop Commitment Agreement); and

13,392 shares of New Common Stock were issued to participants in rights offering extended by the Company to certain holders of general unsecured claims.

The Company entered into the RBL Credit Facility (as defined in Note 8—Long-Term Debt—RBL Credit Facility);

The Company terminated the Prior Credit Facility (as defined in Note 8—Long-Term Debt—Prior Credit Facility), and the holders of claims under the Prior Credit Facility each received its ratable portion of the RBL Credit Facility for its allowed claims. All liens and security interests granted to secure such obligations were automatically terminated and are of no further force and effect;

The Company terminated the DIP Credit Facility (as defined in Note 8—Long-Term Debt—DIP Credit Facility), and the holders of claims under the DIP Credit Facility received payment in full, in cash, for allowed claims. All liens and security interests granted to secure such obligations were automatically terminated and are of no further force and effect;

The holders of certain trade claims, administrative claims, other secured claims and other priority claims that were allowed by the Bankruptcy Court received payment in full in cash upon emergence or through the ordinary course of business after the Emergence Date.

Tax Attributes and Net Operating Loss (“NOL”) Carryforwards

As of December 31, 2020, the Company had substantial tax NOL carryforwards and other tax attributes. Under the U.S. Internal Revenue Code of 1986, as amended (the “Code”), our ability to use these NOLs and other tax attributes may be limited if the Company experiences an “ownership change,” as determined under Section 382 of the Code. Accordingly, on July 13, 2020, the Company obtained a final order from the Bankruptcy Court that was intended to prevent an ownership change during the pendency of the Chapter 11 Cases and therefore protect the Company’s ability to use its tax attributes by imposing certain notice procedures and transfer restrictions on the trading of the Company’s Predecessor Common Stock and Predecessor Preferred Stock.

In general, the order applied to any person or entity that, directly or indirectly, beneficially owned (or would beneficially own as a result of a proposed transfer) at least 4.5% of the Company’s common stock or preferred stock. Such persons were required to notify the Company and (ii) on October 17, 2016, Holdings merged withthe Bankruptcy Court before effecting a transaction involving the Company’s Predecessor Common Stock and intoPredecessor Preferred Stock, and the Company had the right to seek an injunction to prevent the transaction if it might have adversely affected the Company’s ability to use its tax attributes. The order also required any person or entity that, directly or indirectly, beneficially owned at least 50% of the Company’s Predecessor Common Stock and Predecessor Preferred Stock to notify the Company and the Bankruptcy Court prior to claiming any deduction for worthlessness of the Company’s Predecessor Common Stock and Predecessor Preferred Stock for a tax year ending before the Company’s emergence from chapter 11 protection and the Company had the right to seek an injunction to prevent the transaction if it might have adversely affected the Company’s ability to use its tax attributes.

Any purchase, sale or other transfer of, or any claim of a deduction for worthlessness with respect to, the Company’s Predecessor Common Stock and Predecessor Preferred Stock in violation of the restrictions of the order would have been null and void ab initio as an act in violation of a Bankruptcy Court order and would therefore have conferred no rights on a proposed transferee or such holder, as applicable.

However, the Company expects that it will be required to substantially reduce or eliminate certain of its tax attributes, including NOL carryforwards, as a result of cancellation of indebtedness income realized in connection with the ExtractionChapter 11 Cases. Additionally, the consummation of the Plan on the Emergence Date resulted in an “ownership change” under Section 382 of the Code. Absent an applicable exception, if a corporation undergoes an “ownership change,” the amount of its pre-ownership change NOLs that may be utilized to offset future taxable income generally will be subject to an annual limitation equal to the value of its stock immediately prior to the ownership change multiplied by the long-term tax-exempt rate, plus an additional amount calculated based on certain “built in gains” in its assets that may be deemed to be realized within a 5-year period following any ownership change. This limitation, in the case of the ownership change that occurred as a result of the consummation of the Plan, will be subject to additional rules under Sections 382(l)(5) or (l)(6) of the Code, depending upon whether we are eligible for the application of Section 382(l)(5) of the Code and, if so eligible, whether we affirmatively elect not to apply Section 382(l)(5) of the Code. As a result of such limitation, the Company’s ability to utilize any NOLs or other tax attributes that are not eliminated as a result of cancellation of indebtedness income arising from the consummation of the Plan may be materially limited in the future.

Fresh-Start Reporting

Upon the Emergence Date, we began our assessment of our qualifications for fresh-start reporting. In order to qualify for fresh-start reporting, under Accounting Standards Codification (“ASC”) Topic 852 — Reorganizations, (i) the holders of existing voting shares of the Company prior to its emergence must receive less than 50% of the voting shares of the Company outstanding following its emergence from bankruptcy and (ii) the reorganization value of our assets immediately prior to confirmation of the plan of reorganization must be less than the post-petition liabilities and allowed claims. If we qualify for fresh-start reporting, a new reporting entity will be considered to have been created, and, as a result, the Company will allocate the reorganization value of the Company to its individual assets, including property, plant and equipment, based on their estimated fair values. The process of estimating the fair value of the Company’s assets, liabilities and equity upon emergence is currently ongoing and, therefore, neither the amounts nor the qualification for this accounting treatment have been finalized. In support of the Plan, the enterprise value of the Successor Company was estimated and approved by the Bankruptcy Court to be in the range of $875 million to $1.275 billion. On the Emergence Date, pursuant to the terms of the Plan, the Successor Company entered into a $1.0 billion reserve-based credit agreement with an initial borrowing base of $500.0 million. Please see Note 8—Long-Term Debt for discussion of the Successor Company’s debt.

Deconsolidation of Elevation Midstream, LLC

Elevation Midstream, LLC (“Elevation”), a Delaware limited liability company, is focused on the construction and operation of gathering systems and facilities to serve the development of acreage in the Company’s Hawkeye and Southwest Wattenberg areas. Midstream assets of Elevation are represented as the survivinggathering systems and facilities line item within the consolidated balance sheets for any periods ended on or prior to December 31, 2019.

During the first quarter of 2020, Elevation’s then non-controlling interest owner, which owned 100% of Elevation’s preferred stock, per contractual agreement, expanded Elevation’s then five member board of managers by four seats and filled them with managers of their choosing (the “Board Expansion”). Because Extraction had the right to appoint only three of the managers of Elevation before and after Board Expansion, Extraction determined the Company had lost voting control of Elevation, and on March 16, 2020 deconsolidated Elevation and began accounting for the entity as an equity method investment. Though Extraction determined control of Elevation was lost under the voting interest model of consolidation, the Company also determined significant influence was not lost due to (1) Extraction owning 100% of the common stock, (2) Extraction appointing three of the nine managers of Elevation and (3) Extraction’s continuing involvement in the day-to-day operation of Elevation through a management services agreement. Because Extraction also determined the Company is not the primary beneficiary, Elevation Midstream, LLC is not a variable interest entity.


Extraction elected the fair value option to remeasure the Elevation equity method investment and determined it had no fair value. The Company recorded a $73.1 million loss on deconsolidation of the investment in the consolidated statements of operations for the three months ended March 31, 2020. Also during the three months ended March 31, 2020, Elevation determined certain gathering systems and facilities were impaired by $50.3 million as a result of the abandonment of certain projects. In accordance with ASC Topic 323-10-35-20: Investments—equity method and joint ventures, Extraction discontinued applying the equity method for Elevation as the impairment charge would have reduced the investment below zero.

On May 1, 2020, Elevation’s board of managers issued 1,530,000,000 common units at a price of $0.01 per unit to certain of Elevation’s members other than Extraction (the “Capital Raise”). The Capital Raise caused Extraction’s ownership of Elevation to be diluted to less than 0.01%. As a result of the Capital Raise, beginning in May 2020 Extraction began accounting for Elevation under the cost method of accounting. In December 2020, the Company reached a settlement with Elevation (as discussed in Note 16—Commitments and Contingencies — Elevation Gathering Agreements) which was approved by the Bankruptcy Court. As part of the settlement, the Company relinquished its remaining ownership in Elevation and has no more interest in Elevation as of December 31, 2020.

Note 2—Basis of Presentation and Significant Accounting Policies
 
Basis of Presentation
 
The consolidated financial statements include the accounts of the Company, including its wholly‑owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The financial statements included herein were prepared from the records of the Company in accordance with accounting principles generally accepted accounting principles in the United States of America (“GAAP”). In the opinion of management, all adjustments, consisting primarily of normal recurring accruals that are considered necessary for a fair statement of the consolidated financial information, have been included.


Use of Estimates in the Preparation of Financial Statements
 
The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of oil and gas reserves, assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant areas requiring the use of assumptions, judgments and estimates include (1) oil and gas reserves; (2) cash flow estimates used in impairment testing of oil and gas properties and goodwill; (3) depreciation, depletion, amortization and accretion; (4) asset retirement obligations; (5) assigning fair value and allocating purchase price in connection with business combinations, including the determination of any resulting goodwill; (6) accrued revenue and related receivables; (7) valuation of commodity derivative instruments; (8) accrued liabilities; (9) valuation of unit and stock-based payments, and (10) income taxes. Although management believes these estimates are reasonable, actual results could differ from these estimates. The Company evaluates its estimates on an on‑goingon-going basis and bases its estimates on historical experience and on various other assumptions the Company believes to be reasonable under the circumstances.

87

Significant Accounting Policies

Beginning after the Petition Date, the Company has applied ASC Topic 852 — Reorganizations in preparing the consolidated financial statements. ASC 852 requires the financial statements, for periods subsequent to the Chapter 11 Cases’ filing date, to distinguish transactions and events that are directly associated with the reorganization from the ongoing operations of the business. Accordingly, certain expenses incurred during the bankruptcy proceedings, including unamortized debt issuance costs associated with debt classified as liabilities subject to compromise, are recorded as reorganization items. In addition, pre-petition obligations that may be impacted by the chapter 11 process have been classified on the consolidated balance sheets as liabilities subject to compromise. These liabilities are reported at the amounts the Company anticipates will be allowed by the Bankruptcy Court, even if they may be settled for lesser amounts.

GAAP requires certain additional reporting for financial statements prepared between the Petition Date and the date that the Company emerges from bankruptcy, including:

Reclassification of pre-petition liabilities that are unsecured, under-secured or where it cannot be determined that the liabilities are fully secured to a separate line item in the consolidated balance sheets called liabilities subject to compromise; and

Segregation of reorganization items as a separate line in the consolidated statements of operations outside of income from continuing operations.

Debtor-In-Possession

As of December 31, 2020, the Debtors operated as debtors in possession in accordance with the applicable provisions of the Bankruptcy Code. The Bankruptcy Court approved motions filed by the Debtors that were designed primarily to mitigate the impact of the Chapter 11 Cases on the Company’s operations, customers and employees. As a result, the Company conducted normal business activities during 2020 and paid all associated obligations for the period following its bankruptcy filing in the ordinary course of business and was authorized to pay and have paid certain pre-petition obligations, including, among other things, for employee wages and benefits and certain goods and services provided. During the Chapter 11 Cases, transactions outside the ordinary course of business required prior approval of the Bankruptcy Court.

Automatic Stay

Subject to certain specific exceptions under the Bankruptcy Code, the Chapter 11 Cases automatically stayed most judicial or administrative actions against the Debtors and efforts by creditors to collect on or otherwise exercise rights or remedies with respect to pre-petition claims. Absent an order from the Bankruptcy Court, substantially all of the Debtors’ pre-petition liabilities are subject to settlement under the Bankruptcy Code.

Executory Contracts

Subject to certain exceptions, under the Bankruptcy Code, the Debtors may assume, assign, or reject certain executory contracts and unexpired leases subject to the approval of the Bankruptcy Court and certain other conditions. Generally, the rejection of an executory contract or unexpired lease is treated as a pre-petition breach of such executory contract or unexpired lease and, subject to certain exceptions, relieves the Debtors from performing their future obligations under such executory contract or unexpired lease but entitles the contract counterparty or lessor to a pre-petition general unsecured claim for damages caused by such deemed breach. Generally, the assumption of an executory contract or unexpired lease requires the Debtors to cure existing monetary defaults under such executory contract or unexpired lease and provide adequate assurance of future performance. Please refer to Note 5—Liabilities Subject to Compromise and Note 16—Commitments and Contingencies — Delivery Commitments for more information.

Potential Claims

The Debtors have filed with the Bankruptcy Court schedules and statements setting forth, among other things, the assets and liabilities of each of the Debtors, subject to the assumptions filed in connection therewith. These schedules and statements may be subject to further amendment or modification after filing. Certain holders of pre-petition claims that are not governmental units were required to file proofs of claim by the bar date of August 14, 2020. As of March 9, 2021, the Debtors’ have received approximately 2,600 proofs of claim, primarily representing general unsecured claims, for an amount of approximately $5.8 billion. The Bankruptcy Court does not allow for claims that have been acknowledged as duplicates. Approximately 1,100 claims totaling approximately $4.2 billion have been withdrawn, disallowed or are pending approval to be
88

disallowed. These claims will be reconciled to amounts recorded in liabilities subject to compromise in the consolidated balance sheet. Differences in amounts recorded and claims filed by creditors will be investigated and resolved, including through the filing of objections with the Bankruptcy Court, where appropriate. The Company may ask the Bankruptcy Court to disallow claims that the Company believes are duplicative, have been later amended or superseded, are without merit, are overstated or should be disallowed for other reasons. In light of the substantial number of claims filed, the claims resolution process may take considerable time to complete and is continuing even after the Debtors emerged from bankruptcy.

Financial Statement Classification of Liabilities Subject to Compromise

The accompanying consolidated balance sheets as of December 31, 2020 includes amounts classified as liabilities subject to compromise, which represent liabilities the Company anticipates will be allowed as claims in the Chapter 11 Cases. These amounts represent the Debtors’ current estimate of known or potential obligations to be resolved in connection with the Chapter 11 Cases, and may differ from actual future settlement amounts paid. Differences between liabilities estimated and claims filed, or to be filed, will be investigated and resolved in connection with the claims resolution process. The Company will continue to evaluate these liabilities throughout the chapter 11 process and adjust amounts as necessary. Such adjustments may be material. Please refer to Note 5Liabilities Subject to Compromise for more information.

Reorganization Items, Net

The Debtors have incurred and will continue to incur significant costs associated with the reorganization, primarily from damages for rejected or settled contracts and legal and professional fees. The amount of these costs, which since the Petition Date, are being expensed as incurred, are expected to significantly affect the Company’s results of operations. In accordance with applicable guidance, costs associated with the bankruptcy proceedings have been recorded as reorganization items within the Company’s accompanying consolidated statements of operations for the year ended December 31, 2020. Please refer to Note 6—Reorganization Items, Net for more information.

Other Operating Expenses

Other operating expenses were $79.6 million for the year ended December 31, 2020, respectively. There were no other operating expenses for the years ended December 31, 2019 and 2018. The total amount in the current year is made up of the following:

$46.8 million loss contingency from an alleged breach in contract stemming from a purported failure to complete the pipeline extensions connecting certain wells to the Badger central gathering facility prior to April 1, 2020. Please see Note 16—Commitments and Contingencies for further details.
$4.2 million of accrued interest related to the aforementioned alleged breach in contract.
$13.2 million early termination penalty for the revenue contract terminated in June 2020. Please see the section Contract Balance below for further details.
$7.6 million of expenses related to workforce reductions in February and May 2020.
$4.1 million of interest expense on unpaid production taxes recorded in the last half of 2020.
$2.4 million of expenses related to drilling rig standby charges during the second quarter of 2020.
$1.3 million of expenses related to legal accruals and other.
 
Cash and Cash Equivalents
 
Cash and cash equivalents consist of all highly liquid investments that are readily convertible into cash and have original maturities of three months or less when purchased.
Cash Held in Escrow
Cash held in escrow includes deposits for the purchase of certain oil and gas properties as required under the related purchase and sale agreements.

Accounts Receivable
 
The Company records estimated oil and gas revenue receivable from third parties at its net revenue interest. The Company also reflects costs incurred on behalf of joint interest partners in accounts receivable. The Company generally has the ability to withhold future revenue disbursements to recover non‑paymentnon-payment of joint interest billings. On an on‑goingon-going basis, management reviews accounts receivable amounts for collectability and records its allowance for uncollectible receivables

under the specific identification method. based on expected losses. The Company did not0t record any allowance for uncollectible receivables as of or for the years ended December 31, 20172020 and 2016.2019.
 
89

Credit Risk and Other Concentrations
 
The Company’s cash and cash equivalents are exposed to concentrations of credit risk. The Company manages and controls this risk by investing these funds with major financial institutions. The Company often has balances in excess of the federally insured limits.


The Company sells oil, natural gas and NGL to various types of customers, including oil marketers, pipelines and refineries. Credit is extended based on an evaluation of the customer’s financial conditions and historical payment record. The future availability of a ready market for oil, natural gas and NGL depends on numerous factors outside the Company’s control, none of which can be predicted with certainty. For the three-yearsyears ended December 31, 2017,2020, 2019 and 2018, respectively, the Company had the following customers that exceeded 10% of total oil, natural gas and NGL revenues. The Company does not believe the loss of any single purchaser would materially impact its operating results because crude oil, natural gas and NGL are fungible products with well‑establishedwell-established markets and numerous purchasers.

Oil and Gas Properties
 
The Company follows the successful efforts method of accounting for oil and gas properties. Under this method of accounting, all property acquisition costs and development costs are capitalized when incurred and depleted on a units‑of‑productionunits-of-production basis over the remaining life of proved reserves and proved developed reserves, respectively. For the years ended
December 31, 2017, 20162020, 2019 and 2015,2018, the Company excluded $127.4$129.1 million, $98.7$149.7 million and $59.4$144.3 million, respectively, of capitalized costs from depletion related to wells in progress, respectively.progress. For the years ended December 31, 2017, 20162020, 2019 and 2015,2018, the
90

Company recorded depletion expense on capitalized oil and gas properties of $306.7$321.0 million, $197.4$513.7 million and $140.2$426.8 million, respectively.
 
The costs of exploratory wells are initially capitalized pending a determination of whether proved reserves have been found. At the completion of drilling activities, the costs of exploratory wells remain capitalized if a determination is made that proved reserves have been found. If no proved reserves have been found, the costs of exploratory wells are charged to expense. In some cases, a determination of proved reserves cannot be made at the completion of drilling, requiring additional testing and evaluation of the wells. Costs incurred for exploratory wells that find reserves that cannot yet be classified as proved are capitalized if (a) the well has found a sufficient quantity of reserves to justify its completion as a producing well and (b) sufficient progress in assessing the reserves and the economic and operating viability of the project has been made. The status of suspended well costs is monitored continuously and reviewed at each period end. Due to the capital‑intensivecapital-intensive nature and the geological characteristics of certain projects, it may take an extended period of time to evaluate the future potential of an exploration project and the economics associated with making a determination of its commercial viability. As of December 31, 2017,2020 and 2019, the Company had approximately $15.7 million of0 suspended well costs, all capitalized less than one year. The suspended well costs are included in wells in progress at December 31, 2017. These exploratory well costs are pending further engineering evaluation and analysis to determine if economic quantities of oil and gas reserves have been discovered. the Company expects its analysis to be complete in the second half of 2018. As of December 31, 2016, the Company did not have any suspended well costs as the analysis on economic and operating viability of the 2015 project was complete. As of December 31, 2015, the Company had approximately $17.3 million in suspended well costs recorded, all capitalized less than one year, related to four exploratory wells in the northern field. The suspended well costs were included in wells in progress at December 31, 2015. These exploratory well costs were pending further engineering evaluation and analysis to determine if economic quantities of oil and gas reserves had been discovered. At June 30, 2016, the Company completed its evaluation and moved $21.8 million of these suspended well costs to proved oil and gas properties based on the determination of proved reserves.costs.
 
Geological and geophysical costs are expensed as incurred. Costs of seismic studies that are utilized in development drilling within an area of proved reserves are capitalized as development costs. Amounts of seismic costs capitalized are based on only those blocks of data used in determining development well locations. To the extent that a seismic project covers areas of both developmental and exploratory drilling, those seismic costs are proportionately allocated between development costs and exploration expense. The Company expensed $1.4$0.2 million, $0.2 million and $0.4 million of costs associated with exploratory geological and geophysical costs for the year ended December 31, 2017. There were no exploratory geological and geophysical costs incurred for the years ended December 31, 20162020, 2019 and 2015.2018, respectively.
 
The Company capitalizes interest, if debt is outstanding, during drilling operations in its exploration and development activities. For the years ended December 31, 2017, 20162020, 2019 and 2015,2018, the Company capitalized interest of approximately $11.1$5.3 million, $5.2$7.2 million and $5.3$8.2 million, respectively.
 
Net carrying values of retired, sold or abandoned properties that constitute less than a complete unit of depreciable property are charged or credited, net of proceeds, to accumulateaccumulated depreciation, depletion and amortization unless doing so significantly affects the unit-of-production amortization rate, in which case a gain or loss is recognized in income. Gains or losses from the disposal of complete units of depreciable property are recognized to earnings.
 
For sales of entire working interests in unproved properties, gain or loss is recognized to the extent of the difference between the proceeds received and the net carrying value of the property. Proceeds from sales of partial interests in unproved properties are accounted for as a recovery of costs unless the proceeds exceed the entire cost of the property.
 
Impairment of Oil and Gas Properties
 
Proved oil and gas properties are reviewed for impairment annually or when events and circumstances indicate a possible decline in the recoverability of the carrying amount of such property. For all of its fields, the Company estimates the expected future cash flows of its oil and gas properties and compares these undiscounted cash flows to the carrying amount of the oil and gas properties to determine if the carrying amount is recoverable. If the carrying amount exceeds the estimated

undiscounted future cash flows, the Company will write down the carrying amount of the oil and gas properties to fair value. The factors used to determine fair value include, but are not limited to, estimates of reserves, future commodity prices, future production estimates, estimated future capital expenditures, estimated future operating costs, and discount rates commensurate with the risk associated with realizing the projected cash flows. Impairment expense for proved oil and gas properties is reported in impairment of long lived assets and goodwill in the consolidated statements of operations, which increases accumulated depletion, depreciation and amortization. For the year ended December 31, 2017,2020, the Company recognized no$3.6 million related to impairment expense onof the proved oil and gas properties in our northern field and $194.3 million related to oil and gas properties in one of our Core DJ Basin fields, as the fields’ fair values did not exceed the carrying amounts associated with our oil and gas properties. For the year ended December 31, 2019, the Company recognized $14.5 million related to impairment of the proved oil and gas properties in its northern field and $1.3 billion related to assets in its Core DJ Basin field as the field’s fair values did not exceed the carrying amounts associated with its proved oil and gas properties. For the yearsyear ended December 31, 2016 and 2015,2018, the Company recognized $22.5$16.2 million and $9.5 million, respectively, inrelated to impairment expense onof the proved oil and gas properties in its northern field as the Company's northern field. The future undiscounted cash flowsfair value did not exceed itsthe carrying amount associated with its proved oil and gas properties in its northern field and it was determined that the proved oil and gas properties had no remaining fair value. Therefore, the full net book value of these proved oil and gas properties were impaired at June 30, 2016 and 2015. In December 2015, the Company sold proved oil and gas properties for proceeds of $4.7 million. As a result, these assets were fair valued on the date of the transaction in accordance with ASC 360, Property, Plant and Equipment. The net book value of these assets exceeded the fair value by $2.7 million, which the Company recognized as impairment expense. The Company recognized $12.2 million in impairment expense that was attributable to proved oil and gas properties for the year ended December 31, 2015.field.


Unproved oil and gas properties consist of costs to acquire unevaluated leases as well as costs to acquire unproved reserves. The Company evaluates significant unproved oil and gas properties for impairment based on remaining lease term, drilling results, reservoir performance, seismic interpretation or future plans to develop acreage. When successful wells are

drilled on undeveloped leaseholds, unproved property costs are reclassified to proved properties and depleted on a unit‑of‑productionunit-of-production basis. Impairment expense and lease extension payments for unproved properties is reported in exploration and abandonment expenses in the consolidated statements of operations. As a result of the abandonment and impairment of unproved properties, the Company recognized $15.8$253.1 million, $22.3$73.7 million and $16.4$25.7 million in impairmentof abandonment expense for the years ended December 31, 2017, 20162020, 2019 and 2015,2018, respectively.
 
Other Property and Equipment
 
Other property and equipment consists of (i) midstream assets such as rights of way, pipelines, equipment and engineering costs, (ii) compressors, used in Extraction’s oil and gas operations, (iii) land, compressor stations, central tank batteries and disposal well facilities used in Extraction’s oil and gas operations, (ii) land, (iii) rights of ways, pipeline and engineering costs, (iv) office leasehold improvements, (v) the field office, and (vi) other property and equipment including office furniture and fixtures leasehold improvements and computer hardware and software. Impairment expense for other property and equipment is reported in impairment of long lived assets and goodwill in the consolidated statements of operations. No impairment expense was incurred related to midstream facilities for the year ended December 31, 2020. The Company recognized $0.9 million, $0.5$0.1 million and $3.6$0.4 million in impairment expense related to midstream facilities for the yearsyear ended December 31, 2017, 20162019 and 2015,December 31, 2018, respectively, which increased accumulated depreciation recognized in other property and equipment, net of accumulated depreciation. The Company recognized theThese impairment expense for the year ended December 31, 2017expenses were primarily as the result of right-of-way options that were no longer in the Company'sCompany’s plans for developing midstream infrastucture.infrastructure. The Company recognized the impairment expense for the years ended December 31, 2016 and 2015, as the result of contraction in the local oil and gas industry’s near term growth profile, therefore decreasing the need and support for a specifically proposed gas processing facility. Gaingain or loss on the sale of other property and equipment is reported in other operating expensesgain (loss) on sale of property and equipment and assets of unconsolidated subsidiary in the consolidated statementstatements of operations. The Company recognized $0.5$4.5 million, of loss on the sale of other property$3.1 million and equipment related to the disposal of an oil pipeline that was not yet placed into service in the first quarter of 2017.

Gathering systems and facilities balances are evaluated for potential impairment when events or changes in circumstances indicate that their carrying amounts may not be recoverable from expected undiscounted cash flows from the use and eventual disposition of an asset. If the carrying amount of the asset is not expected to be recoverable from future undiscounted cash flows, an impairment may be recognized. Any impairment is measured as the excess of the carrying amount of the asset over its estimated fair value.

In assessing gathering systems and facilities assets for impairment, management evaluates changes in business and economic conditions and their implications for recoverability of the assets’ carrying amounts. The measure of impairments to be recognized, if any, depends upon management’s estimate of the asset’s fair value, which may be determined based on the estimates of future net cash flows or values at which similar assets were transferred in the market in recent transactions, if such data is available. Gathering systems and facilities are recorded at historical cost and depreciated using the straight-line method over 30 years.

In March 2020, Elevation determined certain gathering systems and facilities were impaired by $50.3 million as a result of the abandonment of certain projects. In accordance with ASC Topic 323-10-35-20: Investments—equity method and joint ventures, Extraction discontinued applying the equity method investment for Elevation as the impairment charge would have reduced the investment below zero. For further information on the deconsolidation of Elevation Midstream, LLC, please see Note 1—Business and Organization — Deconsolidation of Elevation Midstream, LLC. No impairment expense was recognized for the years ended December 31, 2019 and 2018 associated with gathering systems and facilities.

Equity Method Investments


Investments in entities for which the Company exercises significant influence, but not control, are accounted for under the equity method.method of accounting. The Company recorded $8.3$44.6 million of such investments included in other non-current assets on the consolidated balance sheets as of December 31, 2017.2019 but had no equity method investment as of December 31, 2020 due to the deconsolidation of Elevation Midstream discussed in Note 1 — Business and Organization — Deconsolidation of Elevation Midstream, LLC. Please refer to Note 16 — Commitments and Contingencies — Delivery Commitments for more information. The Company recognized $0.4$0.5 million, $2.3 million and $2.9 million of net income from such investments, including the accretion of any basis difference between the carrying amount of the investment and the amount of underlying equity in net assets, included in other income on the consolidated statements of operations and equity in earnings of unconsolidated subsidiary, in which we havehad a minority ownership interest on the consolidated statements of cash flows for the years ended December 31, 2020, 2019 and 2018, respectively.

For the year ended December 31, 2017. The Company held no such investments during2019, a gain on sale of unconsolidated subsidiary of $1.0 million was recorded relating to Elevation’s August 2018 Divestiture. In August 2018, Elevation received proceeds of $83.6 million and recognized a gain of $83.6 million for the yearsyear ended December 31, 2016 and 2015.2018, upon the sale of assets of DJ Holdings, LLC, a subsidiary of Discovery Midstream Partners, LP, of which Elevation held a 10% membership interest. The Company acquired its interest in exchange for the contribution of an acreage dedication, which is considered a nonfinancial asset.


Deferred Lease Incentives
 
All incentives received from landlords for office leasehold improvements are recorded as deferred lease incentives and amortized over the term of the respective lease on a straight‑linestraight-line basis as a reduction of rental expense. The Company wrote off $2.6 million of leasehold improvements during the year ended December 31, 2020 due to a consolidation of leased office space.

Debt Discount Costs
93


Debt Issuance Costs
 
Debt issuance costs include origination, legal, engineering, and other fees incurred to issue the debt in connection with the Company’s credit facility, 2021Prior Credit Facility, DIP Credit Facility (as defined in Note 8 — Long Term Debt), 2024 Senior Notes and 20242026 Senior Notes (collectively, the "Senior Notes"“Senior Notes”). Debt issuance costs related to the credit facilityPrior Credit Facility are included in other non-current assets on the consolidated balance sheets and amortized to interest expense on the consolidated statement of operations on a straight‑linestraight-line basis over the respective borrowing term. Debt issuance costs related to the Senior Notes areprior to the Chapter 11 Cases were amortized to interest expense using the effective interest method over the term of the debt. However, as a result of the Chapter 11 Cases, the Company expensed $13.5 million of debt issuance costs pertaining to the Senior Notes to reorganization items, net on the consolidated statements of operations for the year ended December 31, 2020. Debt issuance costs of $1.7 million pertaining to the DIP Credit Facility were expensed to reorganization items, net during the year ended December 31, 2020.
 
Commodity Derivative Instruments
 
The Company has entered into commodity derivative instruments to reduce the effect of price changes on a portion of the Company’s future oil and natural gas production. The commodity derivative instruments are measured at fair value and are included in the accompanying balance sheets as commodity derivative assets and commodity derivative liabilities. The Company has not designated any of the derivative contracts as fair value or cash flow hedges. Therefore, the Company does not apply hedge accounting to the commodity derivative instruments. Net gains and losses on commodity derivative instruments are recorded based on the changes in the fair values of the derivative instruments. Net gains and losses on commodity derivative instruments are recorded in the commodity derivativederivatives gain (loss) line on the consolidated statements of operations. The Company’s cash flow is only impacted when the actual settlements under the commodity derivative contracts result in making or receiving a payment to or from the counterparty. These settlements under the commodity derivative contracts are reflected as operating activities in the Company’s consolidated statements of cash flows.
 
Any premiums paid on derivative contracts are capitalized as part of the derivative assets or derivative liabilities, as appropriate, at the time the premiums are paid. Premium payments are reflected in cash flows from operating activities in the

Company's Company’s consolidated statements of cash flows. Over time, as the derivative contracts settle, the differences between the cash received and the premiums paid or fair value of contracts acquired are recognized in net gains or losses on commodity or interest rate derivatederivative contracts, and the cash received is reflected in cash flows from operating activities in the Company'sCompany’s consolidated statements of cash flows.
 
The Company’s valuation estimate takes into consideration the counterparties’ credit worthiness, the Company’s credit worthiness, and the time value of money. The consideration of these factors resultresults in an estimated exit‑priceexit-price for each derivative asset or liability under a market place participant’s view. Management believes that this approach provides a reasonable, non‑biased,non-biased, verifiable, and consistent methodology for valuing commodity derivative instruments. Please refer to Note 69 — Commodity Derivative Instruments for additional discussion on commodity derivative instruments.
 
Goodwill and Other Intangible Assets
 
The Company applies the provisions of ASC 350, Intangibles-Goodwill and Other.Other. Goodwill represents the excess of the purchase price over the estimated value of the net assets acquired in business combinations. The Company tests goodwill for impairment annually on September 30, or whenever other circumstances or events indicate that the carrying amount of goodwill may not be recoverable. The goodwill test is performed at the reporting unit level, which represents the Company’s oil and gas operations in its coreCore DJ Basin field. If indicators of impairment are determined to exist, an impairment charge is recognized if the carrying value of goodwill exceeds its implied fair value. Any sharp prolonged decreases in the prices of oil and natural gas as well as continued declines in the quoted market price of the Company’s common shares could change the estimates of the fair value of the reporting unit and could result in an impairment charge. The Company performed ana quantitative assessment as of September 30, 2017,2018, which concluded the fair value of the reporting unit was greater than its carrying amount.
The Company identified triggering events as of December 31, 2018, due to the decrease in commodity pricing and the quoted market price of the Company's common shares compared to September 30, 2018. As such, the Company performed a qualitativequantitative assessment as of December 31, 20172018, utilizing an income approach based on estimates of the expected discounted future cash flows of the reporting unit's oil and 2016,gas properties, which concluded the fair value of the reporting unit was more-likely-than-notnot greater than its carrying amount. As a result, the Company recorded goodwill impairment of $54.2 million, the entirety of the balance, for the year ended December 31, 2018. As such, no test for goodwill impairment was necessary for the year ended December 31, 2020 and 2019.
94

Costs relating to the acquisition of internal-use software licenses are capitalized when incurred and amortized over the estimated useful life of the license, which is typically one year or less. to three years. The Company recorded $2.3$0.3 million, $2.2 million and $0.3$3.0 million of capitalized internal-use software costs for the years ended December 31, 20172020, 2019 and 20162018, respectively, on the consolidated balance sheets within the goodwill and other intangiblenon-current assets line item. Accumulated amortization for the years ended December 31, 20172020 and 20162019 was $1.1$6.8 million and $0.1$5.3 million, respectively. The Company recognized $1.0$1.6 million, $2.2 million and $0.1$2.1 million of amortization expense for the years ended December 31, 20172020, 2019 and 2016,2018, respectively. There was no capitalized internal-use software, accumulated amortization or amortization expense for the year ended December 31, 2015.
 
Fair Value of Financial Instruments
 
The Company’s financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, commodity derivative instruments (discussed above) and long‑termlong-term debt. The carrying values of cash and cash equivalents, accounts receivable and accounts payable are representative of their fair values due to their short‑termshort-term maturities. The carrying amountamounts of the Company’s credit facilityPrior Credit Facility and DIP Credit Facility approximates fair value as it bears interest at variable rates over the term of the loan.loans. The Company’s Senior Notes are recorded at cost and the fair value is disclosed in Note 811 — Fair Value Measurements. Considerable judgment is required to develop estimates of fair value. The estimates provided are not necessarily indicative of the amounts the Company would realize upon the sale or refinancing of such instruments.
 
Asset Retirement Obligation
 
The Company recognizes estimated liabilities for future costs associated with the abandonment of its oil and gas properties. A liability for the fair value of an asset retirement obligation and corresponding increase to the carrying value of the related long‑livedlong-lived asset are recorded at the time the Company makes the decision to complete the well or a well is acquired. For additional discussion on asset retirement obligations please refer to Note 710 — Asset Retirement Obligations.
 
Environmental Liabilities
 
The Company is subject to federal, state and local environmental laws and regulations. These laws regulate the release, disposal or discharge of materials into the environment or otherwise relating to environmental protection and may require the Company to remove or mitigate the environmental effects of the discharge, disposal or release of petroleum substances at various sites. Environmental expenditures are expensed or capitalized depending on their future economic benefit. Expenditures that relate to an existing condition caused by past operations and that have no future economic benefit are expensed.
 

Liabilities for expenditures of a non‑capitalnon-capital nature are recorded when environmental assessments and/or remediation is probable, and the costs can be reasonably estimated. Such liabilities are generally undiscounted values unless the timing of cash payments for the liability or component is fixed or determinable. Management has determined that no significant environmental liabilities existed as of December 31, 2017.2020. Please refer to Note 16 — Commitments and Contingencies for additional discussion on environmental liabilities.
 
Revenue Recognition
 
RevenuesRevenue from the sale of oil, natural gas and NGL areNGLs is recognized whenin accordance with ASC 606 - Revenue from Contracts with Customers (“ASC 606”) five-step revenue recognition model to depict the product is delivered at a fixedtransfer of goods or determinable price, title has transferred, and collectability is reasonably assured and evidenced by a contract. Theservices to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. To account for producer imbalances, the Company recognizes revenues from the saleon all sales of oil, natural gas and NGL usingNGLs to third party customers regardless of their ownership percentage and adjusts the sales method of accounting, wherebyunderlifter or overlifter’s claim on the asset’s remaining reserves. In other words, revenue is recorded based on the Company’s share of volume sold, regardless of whether the Company has taken its proportional share of volume produced. A receivable or liability is recognized only to the extent that the Company has an imbalance on a specific property greater than the expected remaining proved reserves. There were no material imbalances atAs of December 31, 2017, 2016 or 2015.2020, 2019, and 2018, the Company had oil imbalances of 1.1, 12.7, and 22.0 MBbl, respectively, which the Company intends to settle with the counterparty in crude oil barrels. On January 1, 2018, the Company adopted ASC 606. See —Adoption of ASC 606 for more information regarding the adoption of this standard.
 
Unit and Stock‑BasedStock-Based Payments
 
The Company and its predecessor, Holdings, has granted restricted unit awards ("RUAs") to certain employees and nonemployee consultants ofunder the Company, restricted stock units ("RSUs"), stock option awards and performance stock awards ("PSAs")LTIP to certain directors, officers and employees, of the Company,including stock options, restricted stock units, performance stock awards, performance stock units, performance cash awards and cash awards which therefore required the Company to recognize the expense in its consolidated financial statements.


95

All unit and stock‑basedstock-based payments to directors, officers and employees are measured at fair value on the grant date and expensed over the relevant service period. Unit‑based payments to nonemployees are measured at fair value at each financial reporting date and expensed over the period of performance, such that aggregate expense recognized is equal to the fair value of the restricted units on the date performance is completed. The fair value of stock option awards is determined by using the Black-Scholes option pricing model. The fair value of the PSAsperformance stock awards was measured at the grant date with a stochastic process method using a Monte Carlo simulation. All unit and stock‑basedstock-based payment expense is recognized using the straight‑linestraight-line method and is included within general and administrative expenses in the consolidated statements of operations and unit and stock-based compensation in the consolidated statements of cash flows. Forfeitures are recorded as they occur. Please refer to Note 1114 — Unit and Stock‑BasedStock-Based Compensation for additional discussion on unit and stock‑basedstock-based payments.
 
Income Taxes
 
The Company accounts for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are calculated by applying existing tax laws and the rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The tax returns and the amount of taxable income or loss are subject to examination by deferral and state taxing authorities.

The Company periodically assesses whether it is more likely than not that it will generate sufficient taxable income to realize its deferred income tax assets, including net operating losses.NOLs. In making this determination, the Company considers all the available positive and negative evidence and makes certain assumptions. The Company considers, among other things, its deferred tax liabilities, the overall business environment, its historical earnings and losses, current industry trends, and its outlook for future years. The Company believes it is more likely than not that certain net operating losses canthe benefit from NOL carryforwards will not be carried forward and utilized.fully realized. In recognition of this risk, the Company has provided a valuation allowance on the deferred tax assets.

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. The Company does not currently have uncertain tax positions.
 
On December 22, 2017, United States legislation referred to as the "Tax Cuts and Jobs Act" (the "TCJA") was signed into law. Many of the provisions of the TCJA are effective for taxable years beginning after December 31, 2017. The TCJA includes changes to the Internal Revenue Code of 1986 (as amended, the "Code"). The most significant change included in the TCJA is a reduction in the corporate federal income tax rate from 35% to 21%. As a result of the enactment date of December

22, 2017, the Company is required to remeasure the deferred tax assets and liabilities at the rate in which they are expected to reverse. This re-measurement of deferred tax assets and liabilities will require the Company to analyze and record a one-time adjustment to reduce the overall deferred tax liability in the consolidated balance sheets and affect a corresponding income tax benefit in the consolidated statements of operations for the year ended December 31, 2017. The Company believes the accounting is complete regarding the revaluation of the deferred tax balances. This resulted in the recording of an income tax benefit of $23.4 million, as well as a corresponding reduction in the deferred tax liability. The Company currently evaluating other potential impacts of the TCJA.
Extraction Oil & Gas Holdings, LLC, the Company’s accounting predecessor, was a limited liability company that was not subject to U.S. federal income tax.
Earnings Per Share
 
Basic earnings per share (“EPS”) includes no dilution and is computed by dividing net income (loss) available to common shareholders by the weighted-average number of shares outstanding during the period. Diluted EPS reflects the potential dilution of securities that could share in the earnings available to common shareholders of the Company. The Company uses the “if-converted” method to determine the potential dilutive effects of its Series A Preferred Stock, and the treasury stock method to determine the potential dilutive effect of outstanding restricted stock units and stock option awards and performance stock awards. The Company’s EPS calculation for the year ended December 31, 2016 includes only the net income (loss) for the period subsequent to IPO and Corporate Reorganization which occurred on October 12, 2016 and has omitted EPS prior to this date. In addition, the basic weighted average shares outstanding calculation for the year ended December 31, 2016 is based on the actual days in which the shares were outstanding for the period from October 12, 2016, to December 31, 2016.
 
Segment Reporting
 
TheBeginning in the fourth quarter of 2018, the Company operates in only one industry segment, which ishad two operating segments, (i) the exploration, development and production of oil, natural gas and NGL (the “exploration and relatedproduction segment”) and (ii) the construction of and support of midstream activities. Theassets to gather and process crude oil and gas production (the “gathering and facilities segment”). Elevation Midstream, LLC comprised the gathering and facilities segment. During the fourth quarter of 2019, the Company’s wholly‑owned midstream subsidiaries are currentlygathering and facilities segment commenced operations. Through March 16, 2020, the results of Elevation were included in the design phaseconsolidated financial statements of Extraction.

Recent Accounting Pronouncements
 
The accounting standard‑settingstandard-setting organizations frequently issue new or revised accounting rules. The Company regularly reviews new pronouncements to determine their impact, if any, on its consolidated financial statements and related disclosures.


In May 2017,March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-09,2020-04, Reference Rate Reform — Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848). This ASU provides an optional expedient and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. In response to the concerns about structural risks of interbank offered rates (IBORs) and, particularly, the risk of cessation of the London Interbank Offered Rate (LIBOR), regulators in several jurisdictions around the world have undertaken reference rate reform initiatives to identify alternative reference rates that are more observable or transaction-based and less susceptible to manipulation. The ASU provides companies with optional guidance to ease the potential accounting burden associated with transitioning away from reference rates that are expected to be discontinued. In January 2021, the FASB issued ASU No. 2021-01, which provides clarificationclarifies that certain provisions in Topic 848, if elected by an entity, apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. The amendments in these ASUs are effective for all entities as of March 12, 2020 through December 31, 2022. The Company is still evaluating the effect of adopting this guidance.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses. In May 2019, ASU No. 2016-13 was subsequently amended by ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses and reduces both (1) diversity in practiceASU No. 2019-05, Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief. ASU No. 2016-13, as amended, affects trade receivables, financial assets and (2)certain other instruments that are not measured at fair value through net income. This ASU replaced the incurred loss approach with an expected loss model for instruments measured at amortized cost and complexity when applyingwas effective for financial statements issued for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. ASU No. 2016-13 will be applied using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance in Topic 718 Compensation - Stock Compensation, tois effective. The Company adopted this ASU on January 1, 2020, and the adoption did not have a changematerial impact on the consolidated financial statements and related disclosures.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) which removes or modifies current fair value disclosures and adds additional disclosures. The update to the termsguidance is the result of the FASB’s test of the principles developed in its disclosure effectiveness project, which is designed to improve the effectiveness of disclosures in the notes to the financial statements. The disclosures that have been removed or conditions of a share-based payment award.modified may be applied immediately with retrospective application. For public entities, the new guidance was effective for fiscal years beginning after December 15, 2019, including interim reporting periods within that reporting period. The Company adopted this ASU on January 1, 2020, and the adoption did not have a material impact on the consolidated financial statements and related disclosures.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software and hosting arrangements that include an internal-use software license. For public entities, the guidance is effective for fiscal years beginning after December 15, 2017,2019, including interim reporting periods within that reporting period. Early adoption is permitted for fiscal years beginning after December 15, 2016, including the interim reporting periods within that fiscal year. The Company has completed its evaluation and the adoption of this ASU is not expected to have a significant effect on its consolidated financial statements and related disclosures.

In February 2017, the FASB issued ASU No. 2017-05, which provided clarification regarding the guidance on accounting for the derecognition of nonfinancial assets. For public entities, the new guidance is effective for fiscal years beginning after December 15, 2017, including interim reporting periods within that fiscal year. The Company is currently evaluating the impact of adopting this ASU, however it is not expected to have a significant effect on its consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU No. 2017-04, which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount. For public entities, the new guidance is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim and annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact of adopting this ASU, however it is not expected to have a significant effect on its consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU No. 2017-01, which clarifies the definition of a business when evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. For public entities, the new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted for transactions for which the acquisition date occurs before the issuance date or effective date of the

amendments, only when the transaction has not been reported in the financial statements that have been issued. The Company is currently evaluating this ASU and believes it could have a material impact to its consolidated financial statements and related disclosures, as it may result in more transactions being accounted for as asset acquisitions rather than business combinations.

In November 2016, the FASB issued ASU No. 2016-18, which intends to clarify how entities should present restricted cash and restricted cash equivalents in the statement of cash flows. This amendment will be effective retrospectively for reporting periods beginning after December 15, 2017, and early adoption is permitted. The Company is currently evaluating the impact of adopting this ASU, however it is not expected to have a significant effect on its consolidated financial statements and related disclosures.

In August 2016, the FASB issued ASU No. 2016-15, which addresses eight specific cash flow issues, including presentation of debt prepayments or debt extinguishment costs, with the objective of reducing the existing diversity in practice. In addition, in November 2016, the FASB issued ASU No. 2016-18, which requires that amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. For public entities, the new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company has completed its evaluation and the adoption of this ASU is not expected to have a significant effect on its consolidated financial statements and related disclosures.

In March 2016, the FASB issued ASU No. 2016-09, which simplifies the accounting for share-based payment award transactions, including: (a) income tax consequences; (b) classification of awards as either equity or liabilities; and (c) classification on the consolidated statement of cash flows. ASU No. 2016-09 was effective for public companies for annual and interim reporting beginning after December 15, 2016, including interim periods within those fiscal years. The Company adopted this guidance during the first quarter of 2017. As a result of adoption of this guidance, the Company elected to account for the forfeiture of stock-based compensation forfeitures as they occur. The adoption of this standard did not have a significant impact on the Company's consolidated financial statements and related disclosures.

In March 2016, the FASB issued ASU No. 2016-06, which clarifies the requirements to assess whether an embedded put or call option is clearly and closely related to the debt host, solely in accordance with the four step decision sequence in FASB ASB Topic 815, Derivatives and Hedging, as amended by this ASU. This standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016 and should be applied using a modified retrospective approach. The Company adopted this ASU in the first quarter of 2017 and the adoption of this ASUon January 1, 2020 which did not have a material impact on the its consolidated financial statements and related disclosures.disclosures as capitalized costs for internal-use software were not material during 2020.


In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) which requires lessee recognition on the balance sheet of a right of use asset and a lease liability, initially measured at the present value of the lease payments. It further requires recognition in the income statement of a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight linestraight-line basis. Under the new standard, certain lease agreements with terms over one year are classified as right-of-use assets and right-of-use liabilities, which gross up the balance sheet. Finally, it requires classification of all cash payments within operating activities in the statements of cash flows. It is effective for fiscal years commencing after December 15, 2018 and early adoption is permitted.2018. The FASB subsequently issued ASU No. 2017-13, ASU No. 2018-01, ASU No. 2018-10 and ASU No. 2018-01,2018-11, which provided additional implementation guidance. The Company is currently evaluatingadopted these lease accounting standards on January 1, 2019 using a modified retrospective transition approach, which applied the impact this ASU will have on its consolidated financial statements and related disclosures. As a part of the assessment work to-date, the Company formed an implementation team, completed trainingprovisions of the new guidance and is developing a strategyat the effective date without adjusting the comparative periods presented. Upon adoption, the Company elected the package of practical expedients permitted under the transition guidance with the new standard, which among other things, requires no reassessment of whether existing contracts are or contain leases as well as no reassessment of lease classification for implementation.existing

leases upon adoption. The Company also elected the optional practical expedient permitted under the transition guidance within the new standard related to land easements that allows it to carry forward its current accounting treatment for land easements on existing agreements. The Company made an accounting policy election to keep leases with an initial term of twelve months or less off of the consolidated balance sheets. Please refer to Note 7 — Leases for further information.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) which establishes a comprehensive new revenue recognition model, referred to as ASC 606, designed to depict the transfer of goods or services to a customer in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. The ASU allows for the use of either the full or modified retrospective transition method. In August 2015, the FASB issued ASU No. 2015-14, which deferred ASU No. 2014-09 for one year, and iswas effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of reporting periods beginning after December 15, 2016. The FASB subsequently issued ASU No. 2016-08, ASU No. 2016-10, ASU No. 2016-11, ASU No. 2016-12, ASU No. 2016-20, ASU No. 2017-13, ASU No. 2017-14 and ASU No. 2017-14,2019-20, which provided additional implementation guidance. The Company completed its reviewRefer to —Adoption of contracts in eachASC 606 for more information.

Adoption of its revenue streams and has developed accounting policies to address the provisions of this ASU. While the Company does not expect operating income (loss) to be materially impacted, the Company does expect total revenues and total expenses to change as a result of certain contracts where title of production transfers to customers at the wellhead. Further, the Company evaluated the design of its pre-adoption and adoption controls and had developed new or modified certain controls to address risks associated with recognizing revenue under the new standard as the Company continues the implementation process. The Company will continue to evaluate the impact of this and other provisions of the ASU on its accounting policies, internal controls, and consolidated financial statements and related disclosures and has not finalized any estimates of theASC 606


potential impacts. The Company will adopt this new standard onOn January 1, 2018, the Company adopted ASC 606. The Company adopted ASC 606 using the modified retrospective method to apply the new standard to all new contracts entered into on or after January 1, 2018 and all existing contracts for which all (or substantially all) of the revenue has not been recognized under legacy revenue guidance. ASC 606 supersedes previous revenue recognition requirements in ASC 605 and includes a five-step revenue recognition model to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services.

Changes to sales of natural gas and NGL, as well as transportation and gathering expenses, are due to the conclusion that certain midstream processing entities are the Company’s customers in natural gas processing and marketing agreements in accordance with the five-step process in ASC 606. This is a change from previous conclusions reached for these agreements utilizing the principal versus agent indicators under ASC 605 where the Company determined it was the principal, the midstream processor was the agent and the third-party end user was its customer. As a result, the Company modified its presentation of revenues and operating expenses for these agreements. Revenues related to these agreements are now presented on a net basis for proceeds expected to be received from the midstream processing entity. Revenues from the sale of oil, natural gas and NGLs, where the Company is a non-operating interest partner, are considered in the scope of ASC 808 - Collaborative Arrangements. Therefore, ASC 606 did not change the presentation of these revenues.

Transportation and gathering expense related to other agreements incurred prior to the transfer of control to the customer at the tailgate of the natural gas processing facilities will continue to be presented as transportation and gathering expense.

Revenues from Contracts with Customers

Sales of oil, natural gas and NGLs are recognized at the point control of the commodity is transferred to the customer and collectability is reasonably assured. The majority of the Company’s contracts’ pricing provisions are tied to a commodity market index, with certain adjustments based on, among other factors, whether a well delivers to a gathering or transmission line, quality of the oil or natural gas, and prevailing supply and demand conditions. As a result, the price of the oil, natural gas and NGLs fluctuates to remain competitive with the other available oil, natural gas and NGL supplies.

Oil Sales

Under the Company’s crude purchase and marketing contracts, the Company generally sells oil production at the wellhead and collects an agreed-upon index price, net of pricing differentials. In this scenario, the Company recognizes revenue when control transfers to the purchaser at the wellhead at the net price received.

To account for producer imbalances, the Company recognizes revenue on all sales to third party customers regardless of their ownership percentage and adjusts the underlifter or overlifter’s claim on the asset’s remaining reserves. As of December 31, 2020, the Company had an oil imbalance of 1.1 MBbl, which the Company intends to settle with the counterparty in crude oil barrels.

98

Natural Gas and NGL Sales

Under the Company’s natural gas processing contracts, the Company delivers natural gas to a midstream processing entity at the wellhead or the inlet of the midstream processing entity’s system. The midstream processing entity gathers and processes the natural gas and remits proceeds to the Company for the resulting sales of NGLs and residue gas. In these scenarios, we evaluate whether we are the principal or the agent in the transaction, and the point at which control of the hydrocarbons transfers to the customer. For those contracts where the Company has concluded the midstream processing entity is the Company’s agent and the third-party end user is its customer (generally the Company’s fixed-fee gathering and processing agreements), the Company recognizes revenue on a gross basis, with transportation and gathering expense presented as an operating expense in the consolidated statements of operations. Alternatively, for those contracts where the Company has concluded the midstream processing entity is its customer and controls the hydrocarbons (generally the Company’s percentage of proceeds gathering and processing agreements), the Company recognizes natural gas and NGL revenues based on the net amount of the proceeds received from the midstream processing company.

In certain natural gas processing agreements, the Company may elect to take its residue gas and/or NGLs in-kind at the tailgate of the midstream entity’s processing plant and subsequently market the product. Through the marketing process, the Company delivers product to the third-party purchaser at a contractually agreed-upon delivery point and receives a specified index price from the purchaser. In this scenario, the Company recognizes revenue when the control transfers to the purchaser at the delivery point based on the index price received from the purchaser. The gathering and processing expense attributable to the gas processing contracts, as well as any transportation expense incurred to deliver the product to the purchaser, are presented as transportation and gathering expense in the consolidated statements of operations.

Performance Obligations

A significant number of the Company’s product sales are short-term in nature with a cumulative adjustmentcontract term of one year or less. For those contracts, the Company has utilized the practical expedient in ASC 606-10-50-14 exempting the Company from disclosure of the transaction price of a contract that has an original expected duration of one year or less.

For the Company’s product sales that have a contract term greater than one year, the Company has utilized the practical expedient in ASC 606-10-50-14(a), which states the Company is not required to retained earnings,disclose the transaction price allocated to remaining performance obligations if necessary.the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Under these sales contracts, each unit of product generally represents a separate performance obligation; therefore future volumes are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.

The Company records revenue on its oil, natural gas and NGL sales at the time production is delivered to the purchaser. However, settlement statements for certain oil, natural gas and NGL sales may not be received for 30 to 90 days after the date production is delivered, and as a result, the Company is required to estimate the amount of production delivered to the customer and the net commodity price that will be received for the sale of these commodity products. The Company records the differences between the revenue estimated and the actual amounts received for product sales in the month that payment is received from the customer.

Contract Balances

The Company had a certain revenue contract with an initial term beginning on November 1, 2016 and continuing until October 31, 2020 after which the contract was to begin an automatic month-to-month renewal unless terminated by either party giving notice at least six months prior to the effective termination date but in no event could either party give such notice earlier than November 1, 2020. Based on the accounting treatment pursuant to ASC 606 — Revenue from Contracts with Customers, the contract term would end on April 30, 2021 because it could be terminated by either party with no penalty effective as of such date. The contract term impacted the amount of consideration that could be included in the transaction price. The Company recognizes revenue and invoices customers once its performance obligations have been satisfied. When it becomes probable that the Company will not meet its performance obligations, the transaction price allocated to the performance obligation is constrained in the amount of the estimated unmet performance obligation and recognized as a reduction to revenue in the period in which the transaction price changes. On June 12, 2020, the Company and the counterparty to the contract mutually cancelled the contract effective June 30, 2020. As a result of the cancellation, for the year ended December 31, 2020, $12.3 million was recorded as a reduction in the transaction price resulting from unsatisfied performance obligations in the period. For the year ended December 31, 2019, the Company allocated $24.7 million to a satisfied performance obligation recognized within oil sales under ASC 606. As a result of the contract termination, the Company incurred an early termination

fee of $13.2 million recorded in other operating expenses for the year ended December 31, 2020. This amount was settled during the third quarter of 2020, and there are no remaining amounts due to the counterparty.

Note 7—Leases

The acquired producing properties contributed no revenueCompany accounts for leases in accordance with ASC 842, Leases, which it adopted on January 1, 2019, applying the modified retrospective transition approach as of the effective date of adoption (see Note 2 — Basis of Presentation and earningsSignificant Accounting Policies — Recent Accounting Pronouncements for impacts of adoption).

The Company enters into operating leases for certain drilling equipment, completions equipment, equipment ancillary to drilling and completions, office facilities, compressors and office equipment. Under ASC 842, a contract is or contains a lease when (i) the contract contains an explicitly or implicitly identified asset and (ii) the customer obtains substantially all of the economic benefits from the use of that underlying asset and directs how and for what purpose the asset is used during the term of the contract in exchange for consideration. The Company assesses whether an arrangement is or contains a lease at inception of the contract. All leases (operating leases), other than those that qualify for the short-term recognition exemption, are recognized as of the lease commencement date on the balance sheet as a liability for its obligation related to the lease and a corresponding asset representing its right to use the underlying asset over the period of use.

The Company’s leases have remaining terms up to four years. Certain of our lease agreements contain options to extend or early terminate the agreement. The lease term used to calculate the lease asset and liability at commencement includes options to extend or terminate the lease when it is reasonably certain that we will exercise that option. When determining whether it is reasonably certain that the Company will exercise an option at commencement, it considers various economic factors, including capital expenditure strategies, the nature, length, and underlying terms of the agreement, as well as the uncertainty of the condition of leased equipment at the end of the lease term. Based on these determinations, the Company generally determines that the exercise of renewal options would not be reasonably certain in determining the expected lease term for leases, other than certain operating compressor leases.

The discount rate used to calculate the present value of the future minimum lease payments is the rate implicit in the lease, when readily determinable. As the Company’s leases generally do not provide an implicit rate, the Company uses its incremental borrowing rate based on its Prior Credit Facility, which includes consideration of the nature, term, and geographic location of the leased asset.

Certain of the Company’s leases include variable lease payments, including payments that depend on an index or rate, as well as variable payments for items such as property taxes, insurance, maintenance, and other operating expenses associated with leased assets. Payments that vary based on an index or rate are included in the measurement of the Company’s lease assets and liabilities at the rate as of the commencement date. All other variable lease payments are excluded from the measurement of the Company’s lease assets and liabilities and are recognized in the period in which the obligation for those payments is incurred. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.

The Company has elected, for all classes of underlying assets, to not apply the balance sheet recognition requirements of ASC 842 to leases with a term of one year or less, and instead, recognize the lease payments in the consolidated statements of operations on a straight-line basis over the lease term. The Company has also made the election, for its certain drilling equipment, completions equipment, equipment ancillary to drilling and completions, compressors and office equipment classes of underlying assets, to account for lease and non-lease components in a contract as a single lease component.

Note 6—9—Commodity Derivative Instruments
 
The Company has entered into commodity derivative instruments, as described below. The Company has utilized swaps, put options and call options to reduce the effect of price changes on a portion of the Company’s future oil and natural gas production.

A swap has an established fixed price. When the settlement price is below the fixed price, the counterparty pays the Company an amount equal to the difference between the settlement price and the fixed price multiplied by the hedged contract volume. When the settlement price is above the fixed price, the Company pays its counterparty an amount equal to the difference between the settlement price and the fixed price multiplied by the hedged contract volume.

A put option has an established floor price. The buyer of the put option pays the seller a premium to enter into the put option. When the settlement price is below the floor price, the seller pays the buyer an amount equal to the difference between the settlement price and the strike price multiplied by the hedged contract volume. When the settlement price is above the floor price, the put option expires worthless. Some of the Company’s purchased put options have deferred premiums. For the deferred premium puts, the Company agrees to pay a premium to the counterparty at the time of settlement.

A call option has an established ceiling price. The buyer of the call option pays the seller a premium to enter into the call option. When the settlement price is above the ceiling price, the seller pays the buyer an amount equal to the difference between the settlement price and the strike price multiplied by the hedged contract volume. When the settlement price is below the ceiling price, the call option expires worthless.


The Company combines swaps, purchased put options, purchased call options, sold put options and sold call options in order to achieve various hedging strategies. Some examples of the Company’s hedging strategies are collars which include purchased put options and sold call options, three-way collars which include purchased put options, sold put options and sold call options, and enhanced swaps, which include either sold put options or sold call options with the associated premiums rolled into an enhanced fixed price swap. The Company has historically relied on commodity derivative contracts to mitigate its exposure to lower commodity prices.


109

The objective of the Company’s use of commodity derivative instruments is to achieve more predictable cash flows in an environment of volatile oil and natural gas prices and to manage its exposure to commodity price risk. While the use of these commodity derivative instruments limits the downside risk of adverse price movements, such use may also limit the Company’s ability to benefit from favorable price movements. The Company may, from time to time, add incremental derivatives to hedge additional production, restructure existing derivative contracts or enter into new transactions to modify the terms of current contracts in order to realize the current value of the Company’s existing positions. The Company does not enter into derivative contracts for speculative purposes.


To reduce the impact of fluctuations in oil and natural gas prices on the Company’s revenues, the Company has periodically entered into commodity derivative contracts with respect to certain of its oil and natural gas production through various transactions that limit the downside of future prices received. Future transactions may include price swaps whereby the Company will receive a fixed price for its production and pay a variable market price to the contract counterparty. Additionally, the Company may enter into collars, whereby it receives the excess, if any, of the fixed floor over the floating rate or pay the excess, if any, of the floating rate over the fixed ceiling price. These hedging activities are intended to support oil and natural gas prices at targeted levels and to manage the Company’s exposure to oil and natural gas price fluctuations.

The use of derivatives involves the risk that the counterparties to such instruments will be unable to meet the financial terms of such contracts. The Company’s derivative contracts are currently with seven2 counterparties, allboth of whomwhich are lenders under our credit agreement.the Predecessor Credit Agreement and the DIP Credit Facility. The Company has netting arrangements with the counterparties that provide for the offset of payables against receivables from separate derivative arrangements with the counterparties in the event of contract termination. The derivative contracts may be terminated by a non‑defaultingnon-defaulting party in the event of default by one1 of the parties to the agreement. There are no credit‑risk‑0 credit risk related contingent features or circumstances in which the features could be triggered in derivative instruments that are in a net liability position at the end of the reporting period.


Effect of Chapter 11 Cases

The commencement of the Chapter 11 Cases constituted a termination event with respect to the Company’s derivative instruments, which permitted the counterparties to such derivative instruments to terminate their outstanding hedges. Such termination events were not stayed under the Bankruptcy Code. During June 2020, certain of the lenders under the Predecessor Credit Agreement elected to terminate their International Swaps and Derivatives Association master agreements and outstanding hedges with the Company for aggregate settlement proceeds of $96.1 million. The proceeds from these terminations were applied to the outstanding borrowings under the Prior Credit Facility.

Note 7—10—Asset Retirement Obligations
 
The Company follows accounting for asset retirement obligations in accordance with ASC 410, Asset Retirement and Environmental Obligations, which requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it was incurred if a reasonable estimate of fair value could be made. The Company’s asset retirement obligations primarily represent the estimated present value of the amounts expected to be incurred to plug, abandon and remediate producing and shut‑inshut-in wells at the end of their productive lives in accordance with applicable local, state and federal laws, and applicable lease terms.  The Company determines the estimated fair value of its asset retirement obligations by calculating the present value of estimated cash flows related to plugging and abandonment liabilities. The significant inputs used to calculate such liabilities include estimates of costs to be incurred; the Company’s credit adjusted discount rates, inflation rates and estimated dates of abandonment. The asset retirement liability is accreted to its present value each period and the capitalized asset retirement costs are depleted with proved oil and gas properties using the unit of production method. Asset retirement obligations are currently presented in the line item liabilities subject to compromise on the consolidated balance sheets.

Note 8—11—Fair Value Measurements
 
ASC 820, Fair Value Measurement and Disclosure, establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions of what market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the reliability of the inputs as follows: 
Level 1: Quoted prices are available in active markets for identical assets or liabilities;
Level 2: Quoted prices in active markets for similar assets and liabilities that are observable for the asset or liability;
Level 3: Unobservable pricing inputs that are generally less observable from objective sources, such as discounted cash flow models or valuations.
 
The financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels. There were no transfers between levels during any periods presented below.
 
The following table presents the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis as of December 31, 20172020 and December 31, 20162019 by level within the fair value hierarchy (in thousands):

The following methods and assumptions were used to estimate the fair value of the assets and liabilities in the tabletables above:
 
Commodity Derivative Instruments
 
The Company determines its estimate of the fair value of derivative instruments using a market based approach that takes into account several factors, including quoted market prices in active markets, implied market volatility factors, quotes from third parties, the credit rating of each counterparty, and the Company’s own credit rating. In consideration of counterparty credit risk, the Company assessed the possibility of whether each counterparty to the derivative would default by failing to make any contractually required payments. Additionally, the Company considers that it is of substantial credit quality and has the financial resources and willingness to meet its potential repayment obligations associated with the derivative transactions. Derivative instruments utilized by the Company consist of swaps, put options, and call options. The oil and natural gas derivative markets are highly active. Although the Company’s derivative instruments are valued using public indices, the

instruments themselves are traded with third‑partythird-party counterparties and are not openly traded on an exchange. As such, the Company has classified these instruments as Level 2.
 
Fair Value of Financial Instruments
 
The Company’s financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, commodity derivative instruments (discussed above) and long‑termlong-term debt. The carrying values of cash and cash equivalents, accounts receivable and accounts payable are representative of their fair values due to their short‑termshort-term maturities. The carrying amount of the Company’s credit facilityPrior Credit Facility and DIP Credit Facility approximated fair value as it bears interest at variable rates over the term of the loan. The fair valuevalues of the 20212024 Senior Notes and 20242026 Senior Notes waswere derived from available market data. As such, the Company has classified the 20212024 Senior Notes and 20242026 Senior Notes as Level 2. Please refer to Note 58 — Long‑TermLong-Term Debt for further information. The Company’s policy is to recognize transfers between levels at the end of the period.

The Company uses an income approach analysis based on the net discounted future cash‑cash flows of producingproved property. The future cash‑flows are based on Management’s estimates forCompany calculates the future. Unobservable inputs included future estimatesestimated fair values of its proved property oil and gas production, asassets using a discounted future cash flow model. Significant inputs associated with the case may be, from the Company’s reserve reports, commodity prices based on the sales contract terms or forward price curves,calculation of discounted future net cash flows include estimates of (i) recoverable reserves, (ii) future operating and development costs, (iii) future commodity prices, and a discount rate based on(iv) a market-based weighted average cost of capital (all of whichcapital. The Company utilized the NYMEX strip pricing, adjusted for differentials, to value the reserves. These are classified as Level 3 inputs withinfair value assumptions. At December 31, 2020, the Company’s estimate of commodity prices for purposes of determining discounted future cash flows ranged from a 2021 price of $48.29 per barrel of oil decreasing to a 2022 price of $46.76 per barrel of oil and decreasing further to a 2025 price of $44.84 per barrel of oil. Natural gas prices ranged from a 2021 price of $2.65 per Mcf decreasing to a 2025 price of $2.52 per Mcf. NGL prices ranged from a 2021 price

Nodid not exceed the Company’s carrying amount attributable primarily to certain downward adjustments to the Company’s reserves due to expirations due to the SEC five year drilling rule caused by the change in business strategy to focus on cash flow rather than maximizing production and reserves growth. Additionally, downward revisions were due to altering the development plan to increase the spacing between wellbores, thus drilling fewer wells, as well as negative performance revisions. For the year ended December 31, 2019, the Company recognized $1.3 billion in impairment expense on its proved oil and gas properties related to assets in its Core DJ Basin field as the fair value did not exceed the Company’s carrying amount attributable primarily to certain downward adjustments to the Company’s reserves due to expirations due to the SEC five year drilling rule caused by the change in business strategy to focus on cash flow rather than maximizing production and reserves growth.

The future undiscounted cash flows did not exceed its carrying amount associated with its proved oil and gas properties in the Company’s northern fieldCore DJ Basin field. For the years ended December 31, 2020, 2019 and it was determined that2018, the Company recognized $3.6 million, $14.5 million and $16.2 million, respectively in impairment expense on its proved oil and gas properties had no remainingrelated to assets in its northern field as the fair value. Therefore,value did not exceed the full net book value of theseCompany’s carrying amount attributable primarily to certain downward adjustments to the Company’s economically recoverable proved oil and natural gas properties were impaired at June 30, 2016 and 2015, respectively. Additionally, during 2015, the Company sold proved oil and gas properties for proceeds of $4.7 million. In connection with the sale, the Company determined that assets’ net book value exceeded the fair value of such properties by $2.7 million. The Company recognized that amount as an impairment expense for the year ended December 31, 2015.reserves.

The Company applies the provisions of ASC 350, Intangibles-Goodwill and Other. Goodwill represents the excess of the purchase price over the estimated value of the net assets acquired in business combinations. The Company tests goodwill for impairment annually on September 30, or whenever other circumstances or events indicate that the carrying amount of goodwill may not be recoverable. The goodwill test iswas performed at the reporting unit level, which representsrepresented the Company’s oil and gas operations in its coreCore DJ Basin field. If indicators of impairment are determined to exist, an impairment charge is recognized if the carrying value of goodwill exceeds its implied fair value. Any sharp prolonged decreases in the prices of oil and natural gas as well as continued declines in the quoted market price of the Company’s common shares could change the

estimates of the fair value of the reporting unit and could result in an impairment charge. The Company performed ana quantitative assessment as of September 30, 2017,2018, which concluded the fair value of the reporting unit was greater than its carrying amount.
The Company identified triggering events as of December 31, 2018, due to the decrease in commodity pricing and the quoted market price of the Company’s common shares compared to September 30, 2018. As such, the Company performed a qualitativequantitative assessment as of December 31, 20172018, utilizing an income approach based on estimates of the expected discounted future cash flows of the reporting unit’s oil and 2016,gas properties, which concluded the fair value of the reporting unit was more-likely-than-notnot greater than its carrying amount. As a result, the Company recorded goodwill impairment of $54.2 million, the entirety of the balance, for the year ended December 31, 2018. As such, no test for goodwill impairment was necessary for the years ended December 31, 2020 and 2019.
 
The Company’s other non‑recurringnon-recurring fair value measurements include the purchase price allocations for the fair value of assets and liabilities acquired through business combinations, please refer to Note 4 — Acquisitions.combinations. The fair value of assets and liabilities acquired through business combinations is calculated using a discounted‑discounted cash flow approach using levelLevel 3 inputs. Cash flow estimates require forecasts and assumptions for many years into the future for a variety of factors, including risk‑adjustedrisk-adjusted oil and gas reserves, commodity prices, development costs and operating costs, based on market participant assumptions. The fair value of assets or liabilities associated with purchase price allocations is on a non‑recurringnon-recurring basis and is not measured in periods after initial recognition.

The aggregate liquidation preference when the units were sold was $150.0 million and $100.0 million, respectively. These Preferred Units represent the noncontrolling interest presented on the consolidated balance sheets, consolidated statements of operations and consolidated statements of changes in the TCJA have an effective datestockholders’ equity (deficit) and noncontrolling interest for years beginning afterperiods ended on or prior to December 31, 2017, including the lowering of the U.S. corporate rate from 35 percent to 21 percent. However, as a result of the enactment date of December 22, 2017, the Company is required to remeasure the deferred tax assets and liabilities at the rate in which they are expected to reverse. The Company provisionally recorded an income tax benefit in the amount of $23.4 million related to the remeasurement of the net deferred tax liability. The Company is currently evaluating other potential impacts of the TCJA.

The SEC staff has issued Staff Accounting Bulletin No. 118, which allows registrants to record provisional amounts during a one year "measurement period" similar to that used when accounting for business combinations. Impacts of this TCJA are expected to be recorded at the time a reasonable estimate for all or a portion of the effects can be made, and provisional amounts can be recognized and adjusted as information becomes available, prepared or analyzed. The Company has made a reasonable estimate and recorded the provisional deferred tax liability regarding the 100% cost recovery of qualified property acquired and placed in service after September 27, 2017 in the amount of $13.0 million. Also, the Company has made a reasonable estimate and recorded a portion of the deferred tax asset of $13.9 million related to stock-based compensation as provisional associated with covered employees. We believe these compensation plans for covered employees continue to qualify as deductible and would be grandfathered under the IRC Sec. 162(m) as of December 31, 2017.

The tax consequences of items taking effect after December 31, 2017 will be analyzed by the Company during 2018, some of the items the Company has identified that will have an impact on the Company are; i) deductibility of future compensation and awards for covered employees, ii) deductibility of meals and entertainment, iii) interest expense deductions, iv) the repeal of like-kind exchanges for non-real property, v) the repeal of the corporate alternative minimum tax and vi) the limitation of the use of NOLs to 80 percent of taxable income. The Company will make a good faith effort to analyze and complete the accounting under ASC Topic 740 of these items prior to the end of the measurement period
Holdings, the Company’s accounting predecessor, was a limited liability company that was not subject to U.S. federal income tax.2019. As part of the Corporate Reorganization,July 2018 transaction, the membersCompany committed to Elevation that it would drill at least 297 qualifying wells in the acreage dedicated to Elevation by December 31, 2023, subject to reductions if Elevation does not invest the full amount of Holdings exchangedcapital as initially anticipated. Pursuant to the Fourth Amendment to the Elevation Gathering Agreements between Elevation and Extraction, this drilling commitment would be eliminated, if and only if all of their member unitsElevation Preferred Units have been redeemed in full or are otherwise no longer outstanding. Please see Note 16 — Commitments and Contingencies — Elevation Gathering Agreements for shares of the Company’s common stock. For additional discussionfurther details on the Corporate Reorganization, see settlement to reduce this drilling commitment.

Upon deconsolidation of Elevation Midstream, LLC as discussed in Note 1 — Business and Organization.Organization — Deconsolidation of Elevation Midstream, LLC, the $270.5 million Elevation preferred unit balance in the noncontrolling interest line item of the consolidated balance sheets as of March 31, 2020 was removed. The amount comprises the line item effects of deconsolidation of Elevation Midstream, LLC on the consolidated statements of changes in stockholders’ equity (deficit) and noncontrolling interest as of March 31, 2020.

During the twenty-eight months following the July 3, 2018 Preferred Unit closing date, Elevation is required to pay the Purchaser a quarterly commitment fee payable in cash or in kind of 1.0% per annum on any undrawn amounts of such additional $250.0 million commitment. For the year ended December 31, 2020, due to the deconsolidation of Elevation during the first quarter of 2020, the Company’s consolidated statements excluded all commitment fees paid-in-kind from the Preferred Unit commitment fees and dividends paid-in-kind line item in the consolidated statements of changes in stockholders’ equity (deficit) and noncontrolling interest. For the years ended December 31, 2020 and 2019, respectively, Elevation recognized $0.6 million and $3.1 million of commitment fees paid-in-kind.

The Elevation Preferred Units entitle the Purchaser to receive quarterly dividends at a rate of 8.0% per annum. The Dividend is currently payable solely in cash. For the year ended December 31, 2020, due to the deconsolidation of Elevation during the first quarter of 2020, the Company’s consolidated statements excluded all dividends paid-in-kind from the Preferred Unit commitment fees and dividends paid-in-kind line item in the consolidated statements of changes in stockholders’ equity (deficit) and noncontrolling interest. For the years ended December 31, 2020 and 2019, respectively, Elevation recognized $5.5 million and $16.9 million of dividends paid-in-kind.

Elevation Common Units

In May 2020, Elevation’s board of managers issued 1,530,000,000 common units at a price of $0.01 per unit to certain of Elevation’s members other than Extraction through the Capital Raise. The Capital Raise caused Extraction’s ownership of Elevation to be diluted to less than 0.01%. As a result of the Corporate Reorganization,Capital Raise, beginning in May 2020 Extraction began accounting for Elevation under the cost method of accounting. In December 2020, the Company identifiedreached a settlement with Elevation, which was approved by the Bankruptcy Court and established the deferred tax assets and liabilities for differences between the book and tax basis of Holdings. The Company recorded a net deferred tax liability of approximately $135.3 million. As this Corporate Reorganization is being accounted for as a transaction under common control the offsetpart of the net deferred tax liabilitysettlement the Company relinquished all of its remaining ownership in Elevation.

Management considers whether some portion or all of the deferred tax assets will be realized based on a more likely than not standard of judgment. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable

income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. The Company has net operating lossNOL carryforwards (NOLs) for U.S. income tax purposes that have been generated from the Company'sCompany’s operations through December 31, 2020 of approximately $834.7 million. Due to the Act, these NOLs will not expire$1.3 billion, of which $833.6 million was generated before January 1, 2018 and are not subject to the 80 percent limitation of taxable income arisingincome. Such NOLs will expire beginning in future2036. As of December 31, 2020, the Company had $324.3 million of intangible drilling costs that were capitalized under Code Section 59(e). We believe it is more likely than not that the benefit from NOL carryforwards and other tax years.attributes will not be fully realized. In recognition of this risk, we have provided a valuation allowance on the deferred tax assets.
 
The utilization of such NOL carryforwards may be limited upon the occurrence of certain ownership changes as stipulated in Section 382 of the Internal Revenue Code of 1986, as amended (the "Code"“Code”). As of December 31, 2017,2020, the Company determined that the statutory provision of Section 382 will not limit the Company’s ability to realize future tax benefits. As of December 31, 2017, the Company believes it will be able to generate sufficient future taxable income within the carryforward period and accordingly, believes that it is more likely than not that its deferred income tax assets will be fully realized. The Company files income tax returns in the U.S. federal jurisdiction and in Colorado. The statute of limitations related to the 20162017, 2018 and 20172019 tax returns areis open through 20202021, 2022 and 2021 respectively,2023, respectively; however, the ability for the tax authority to adjust the NOL will continue until three years after the NOL is utilized.

As of December 31, 2017,2020, the Company believes that it has no0 liability for uncertain tax positions. If the Company were to determine there wereare any uncertain tax positions, the Company would recognize the liability and related interest and

penalties within income tax expense. As of December 31, 2017,2020, the Company had no0 provision for interest or penalties related to uncertain tax positions.

Effect of Chapter 11 Cases and Emergence from Chapter 11 Cases

On July 13, 2020 the Bankruptcy Court entered a final order approving certain procedures (including notice requirements) that certain shareholders and potential shareholders were required to comply with during the pendency of the Chapter 11 Cases regarding transfers of, or declarations of worthlessness with respect to, the Company’s Predecessor Common Stock and Predecessor Preferred Stock, as well as certain obligations with respect to notifying the Company with respect to current share ownership, each of which were intended to preserve the Company’s ability to use its NOLs to offset possible future U.S. taxable income by reducing the likelihood of an ownership change under Section 382 of the Code during the pendency of the Chapter 11 Cases.

The consummation of the Plan on the Emergence Date resulted in an “ownership change” of the Company under Section 382 of the Code. Absent an applicable exception, if a corporation undergoes an “ownership change,” the amount of its pre-ownership change net operating losses that may be utilized to offset future taxable income generally will be subject to an annual limitation equal to the value of its stock immediately prior to the ownership change multiplied by the long-term tax exempt rate, plus an additional amount calculated based on certain “built in gains” in its assets that may be deemed to be realized within a 5-year period following any ownership change. This limitation, in the case of the ownership change that occurred as a result of the consummation of the Plan, will be subject to additional rules under Sections 382(l)(5) or (l)(6) of the Code, depending upon whether we are eligible for the application of Section 382(l)(5) of the Code and, if so eligible, whether we affirmatively elect not to apply Section 382(l)(5) of the Code. As a result of such limitation, the Company’s ability to utilize any NOLs or other tax attributes that are not eliminated as a result of cancellation of indebtedness income arising from the consummation of the Plan may be materially limited in the future.

The CARES Act provides relief to corporate taxpayers by permitting a five year carryback of 2018-2020 NOLs, removing the 80% limitation on the carryback of those NOLs, increasing the Section 163(j) 30% limitation on interest expense deductibility to 50% of adjusted taxable income for 2019 and 2020 as well as allowing 2019 adjusted taxable income to be utilized for 2020 limitation purposes, and accelerating refunds for minimum tax credit carryforwards, along with a few other provisions.

Performance Stock Awards

The Company granted performance stock awards (“PSAs”) to certain executives under the 2016 LTIP in October 2017, March 2018, April 2019 and March 2020. The number of shares of the Company’s common stock that may be issued to settle these various PSAs ranges from zero to two times the number of PSAs awarded. PSA’s that settle in cash are presented as liability awards. Generally, the shares issued for PSAs are determined based on the satisfaction of a time-based vesting schedule and a weighting of one or more of the following: (i) absolute total stockholder return (“ATSR”), (ii) relative total stockholder return (“RTSR”), as compared to the Company’s peer group and (iii) cash return on capital invested (“CROCI”) or return on invested capital (“ROIC”) measured over a three-year period and vest in their entirety at the end of the three-year measurement period. Any PSAs that have not vested at the end of the applicable measurement period are forfeited. The vesting criterion that is associated with the RTSR is based on a comparison of the Company’s total shareholder return for the measurement period compared to that of a group of peer companies for the same measurement period. As the ATSR and RTSR vesting criteria are linked to the Company’s share price, they each are considered a market condition for purposes of calculating the grant-date fair value of the awards. The vesting criterion that is associated with the CROCI and ROIC are considered a performance condition for purposes of calculating the grant-date fair value of the awards.

The fair value of the PSAs was measured at the grant date with a stochastic process method using a Monte Carlo simulation. Significant assumptions used in this simulation include the Company’s expected volatility, risk-free interest rate based on U.S. Treasury yield curve rates with maturities consistent with the measurement period as well as the volatilities for each of the Company’s peers.

(1)The number of awards assumes that the associated maximum vesting condition is met at the target amount. The final number of shares of the Company’s common stock issued may vary depending on the performance multiplier, which ranges from zero to one for the 2017 and 2018 grants and ranges from zero to two for the 2019 and 2020 grants, depending on the level of satisfaction of the vesting condition.
(2)The Company approved retention agreements on June 12, 2020 with certain executives and senior managers. These retention agreements, are subject to repayment upon a resignation without “good reason” or termination of employment for “cause” before specified dates and events. As a condition to participating in the revised compensation program, the equity compensation awards granted in 2020 were forfeited.

Stock Options
 
Expense on the stock options areis recognized on a straight-line basis over the service period of the award less awards forfeited. The fair value of the stock options werewas measured at the grant date using the Black ScholesBlack-Scholes valuation model. The Company utilizesutilized the "simplified"“simplified” method to estimate the expected term of the stock options granted as at the time there iswas limited historical exercise data available in estimating the expected term of the stock options. Expected volatility is based on the volatility of the historical stock prices of the Company’s peer group. The risk-free rates are based on the yields of U.S. Treasury instruments with comparable terms. A dividend yield and forfeiture rate of zero0 were assumed. Stock options granted under the 2016 LTIP vest ratably over three years and are exercisable immediately upon vesting through the tenth anniversary of the grant date. To fulfill options exercised, the Company issueswill issue new shares.

Performance Stock Awards


The fair value of the PSAs was measured at the grant date with a stochastic process method using a Monte Carlo simulation. A stochastic process is a mathematically defined equation that can create a series of outcomes over time. Those outcomes are not deterministic in nature, which means that by iterating the equations multiple times, different results with be obtained for those iterations. In the case of the Company's PSAs, the Company cannot predict with certainty the path its stock price or the stock prices of its peer will take over the performance period. By using a stochastic simulation, the Company can create multiple prospective stock pathways, statistically analyze these simulations, and ultimately make inferences regarding the most likely path the stock price will take. As such, because future stock prices are stochastic, or probabilistic with some direction in nature, the stochastic method, specifically the Monte Carlo Model, is deemed an appropriate method by which to determine the fair value of the PSAs. Significant assumptions used in this simulation include the Company's expected volatility, risk-free interest rate based on U.S. Treasury yield curve rates with maturities consistent with the measurement period as well as the volatilities for each of the Company's peers.

The assumptions used in valuing the PSAs granted were as follows:

Incentive Restricted Stock Units (“Incentive RSUs”)
 
In November 2016, after the Holdings’ Incentive Units were converted to the 9.1 million shares of common stock, holdersOfficers of the Holding’s Incentive UnitsCompany contributed 2.7 million shares of common stock to Extraction Employee Incentive, LLC (“Employee Incentive”), which is owned solely by certain officers of the Company. Employee Incentive issued restricted stock units (“Incentive RSUs”) to certain employees. Incentive RSUs vestvested over a three year-year service period, with 25%, 25% and 50% of the units vesting in year one, two and three, respectively. On July 17, 2017, the partners of Employee Incentive amended the vesting schedule in which 25% vested immediately and the remaining Incentive RSUs vest 25%, 25% and 25% each six months thereafter, over the remaining 18 month service period. Grant date fair value was determined based on the value of Extraction’sthe Company’s common stock on the date of issuance. The Company assumed a forfeiture rate of zero0 as part of the grant date estimate of compensation cost. On July 10, 2017, the partners of Employee Incentive amended the vesting schedule in which 25% vested on July 17, 2017 and the remaining Incentive RSUs will vest 25%, 25% and 25% each six months thereafter, over the remaining 18 months service period. Grant date fair value was determined based on the value of Extraction’s common stock on the date of issuance. The Company assumed a forfeiture rate of zero as part of the grant date estimate of compensation cost. As of January 1, 2017, the Company elected to account for stock-based compensation forfeitures as they occur, as a result of the adoption of ASU No. 2016-09. The Company withholds shares as Incentive RSUs vest to satisfy tax withholding obligations of employees and as these shares are issued and outstanding, the withheld shares are included in treasury stock on the consolidated balance sheets.
 
The Company recorded $17.30 stock-based compensation costs related to Incentive RSUs for the year ended December 31, 2020. The Company recorded $0.8 million and $2.4$19.6 million of stock-based compensation costs related to Incentive RSUs for the years ended December 31, 20172019 and 2016,2018, respectively. No stock-based compensation costs related to Incentive RSUs were recorded for the year ended December 31, 2015.

Holdings’ Membership Unit Incentive Plan
On May 29, 2014, Holdings adopted the 2014 Membership Unit Incentive Plan (“2014 Plan”). The 2014 Plan provided for the compensation of employees, non‑employee managers and consultants of the Company and its affiliates through grants of restricted unit awards (“Holdings’ RUAs”) and incentive units (“Holdings’ Incentive Units”). The 2014 Plan was terminated as a result of the Corporate Reorganization in October 2016.

Holdings’ RUAs
Holdings’ RUAs vested over a three‑year service period, with 25%, 25% and 50% of the units vesting in year one, two and three, respectively. The Company estimated fair value of the RUAs on their grant date based upon estimated volatility, market comparable risk free rate, estimated forfeiture rate and a discount for lack of marketability. Grant date fair value was determined based on the value of Holdings’ Equity Units on the date of the grant. Due to a lack of historical data, the Company used the experience of other entities in the same industry to estimate a forfeiture rate. Expected forfeitures are then included as part of the grant date estimate of compensation cost.
No unit-based compensation costs related to Holdings' RUA grants were recorded for December 31, 2017. The Company recorded $16.8 million and $5.3 million of unit-based compensation costs related to Holdings’ RUA grants for the years ended December 31, 2016 and 2015, respectively. These costs are included in the consolidated statements of operations within the general and administrative expenses line item. In connection with the Corporate Reorganization in 2016, the Holdings Membership Unit Incentive Plan ("2014 Plan") was terminated. As of December 31, 2017, there is no unrecognized compensation cost related to unvested RUAs granted to employees.

PRL RUAs
PRL granted RUAs to certain employees, including Extraction employees (“PRL RUAs”). PRL RUAs vested over a three years service period, with 25%,  25% and 50% of the units vesting in year one, two and three, respectively. Grant date fair value was determined based on the value of PRL’s Equity Units on the date of the grant. PRL uses its past experience to estimate a forfeiture rate and expected forfeitures are included as part of the grant date estimate of compensation cost.
No unit-based compensation costs related to PRL RUA grants were recorded for the year ended December 31, 2017.  The Company recorded $0.5 million and $0.8 million of unit-based compensation costs related to PRL RUA grants for the years ended December 31, 2016 and 2015, respectively. These costs are included in the consolidated statements of operations within the general and administrative expenses line item. In connection with the Corporate Reorganization in 2016, the Holdings Membership Unit Incentive Plan ("2014 Plan") was terminated. As of December 31, 2017, there was no unrecognized compensation cost related to the PRL RUAs as all awards were fully vested.
Holdings’ Incentive Units
In accordance with the 2014 Plan and the Holdings LLC Agreement, Holdings issued 3.0 million Holdings’ incentive units to certain members of management in the fourth quarter of 2015. All of Holdings’ Incentive Units were non‑voting and subject to certain vesting and performance conditions. The Holdings’ Incentive Units vested over a three year service period, with 25%,  25% and 50% of the units vesting in year 1, year 2 and year 3, respectively (with vesting between the first and third anniversaries occurring pro-rata based on the number of full months elapsed since the last vesting date), and in full upon a change of control, as defined in the Holdings LLC Agreement. The Holdings’ Incentive Units were accounted for as liability awards under ASC 718, Compensation-Stock Compensation, with compensation expense based on period‑end fair value.

In connection with the IPO, the Board of Managers of Holdings accelerated the vesting of the Holdings’ Incentive Units. The Company’s IPO and change of control triggered the conversion of these units into approximately 9.1 million common shares of the Company based on the 10-day volume weighted average price of the Company’s common stock following its IPO as set forth in the Holdings Third Amended and Restated LLC Agreement. For the year ended December 31, 2016, the Company recognized approximately $172.1 million in non-cash, share-based compensation expense in connection with the conversion of the Holdings’ Incentive Units into the Company’s common stock. No incentive compensation expense was recorded for the year ended December 31, 2015 because it was not probable that the performance criterion would be met.

Note 12—15—Earnings (Loss) Per Share
 
Basic earnings per share (“EPS”) includes no dilution and is computed by dividing net income (loss) available to common shareholders by the weighted-average number of shares outstanding during the period. Diluted EPS reflects the potential dilution of securities that could share in the earnings available to common shareholders of the Company. The Company uses the “if-converted” method to determine potential dilutive effects of Series A Preferred Stock and the treasury method to determine the potential dilutive effects of outstanding restricted stock awards and stock options and PSAs.options.

As part of the settlement and amended agreements, all prior minimum volume commitments were relieved. There are no minimum volume commitments in the amended agreements.

The Company entered into another long-term gas gathering and processing agreement with a different third party midstream provider in February 2019. This agreement commenced in January 2020 and has a term of ten years with an annual minimum volume commitment of 13.0 Bcf. This agreement also includes a commitment to sell take-in-kind NGLs from other processing agreements of 4,000 Bbl/d in year one and 7,500 Bbl/d in years two through seven with the ability to roll up to a 10% shortfall in a given month to the subsequent month.

In collaboration with several other producers and a midstream provider, on December 15, 2016 and August 7, 2017, the Company agreed to participate in expansions of natural gas gathering and processing capacity in the DJ Basin. The plan includes twoincluded 2 new processing plants as well as the expansion of related gathering systems, which are currently expected to be completed by mid-2018systems. The first plant commenced operations in August 2018 and mid-2019, respectively, although the exact start-up dates are undetermined at this time.second plant commenced operations in July 2019. The Company’s share of these commitments will require an incremental 51.5 MMcf and 20.6 MMcf per day, respectively, over a baseline volume of 65 MMcf per day to be delivered after the plants'plants’ in-service dates for a period of seven years thereafter. The Company may be required to pay a shortfall fee for any volumesincremental volume deficiencies under these commitments. These contractual obligations can be reduced by the Company’s proportionate share of the collective volumes delivered to the plants by other third partythird-party incremental volumes available to the midstream provider at the new facilities that are in excess of the total commitments. The Company is also required for the first three years of each contract to guarantee a certain target profit margin on these volumes sold. Under its current drilling plans,

In July 2019, the Company expectsentered into 3 long-term contracts to meet thesesupply 125,000 dekatherms of residue gas per day for five years to a transportation company. On November 24, 2020, the Bankruptcy Court ruled in favor of the Company rejecting this contract with an effective date as of December 10, 2020, and, therefore, the Company has no remaining minimum volume commitments.

Elevation Gathering Agreements

In July 2018, the Company entered into three long-term gathering agreements (the “Elevation Gathering Agreements”) for gas, crude oil and produced water with Elevation. Under the agreements, the Company agreed to drill 100 wells in Broomfield and 325 wells in Hawkeye by December 31, 2023 if both facilities are to be built, subject to adjustments if less capital is spent. If the Company wer to fail to complete the wells by the applicable deadline, then it would be in breach of the agreement and Elevation could attempt to assert damages against Extraction and its affiliates. During the first quarter of 2020, Elevation postponed indefinitely further development of gathering systems and facilities that were to be constructed to service the Company’s acreage in Hawkeye and another project in the Southwest Wattenberg area. Due to the decision to not complete the Hawkeye facilities and based on the amount of capital invested, Elevation had asserted that the drilling commitment now consists of 297 wells in the Broomfield area of operations with a deadline of December 31, 2022. As discussed below, in December 2020 this drilling commitment was further reduced to 106 wells.

In April 2019, the Elevation Gathering Agreements were amended to provide for, among other amendments, the inclusion of additional gathering facilities that would produce into Elevation’s Badger facility.

In December 2019, the Elevation Gathering Agreements were further amended to provide Elevation additional connection fees that are consistent with market terms (the “Connect Fees”). In the fourth quarter of 2019, the Company incurred and paid $19.5 million for Connect Fees pursuant to the Elevation Gathering Agreements, and in the first quarter of 2020 the Company incurred and paid $23.5 million. The Company did not incur additional Connect Fees for the year ended December 31, 2020.

In April 2020, pursuant to the amendment to the Elevation Gathering Agreements made in April 2019 discussed above, Elevation asserted that the additional gathering facilities that were required to be completed by April 1, 2020 were not built thus Extraction must make a payment to Elevation in the amount of 135% of all costs incurred by Elevation as of such date for the development and construction of such additional gathering facilities. On April 2, 2020, Elevation demanded payment of $46.8 million due to an alleged breach in contract stemming from a purported failure to complete the pipeline extensions connecting certain wells to the Badger central gathering facility prior to April 1, 2020. The Company recorded the amount in liabilities subject to compromise on the condensed consolidated balance sheet as of December 31, 2020 and in other operating expenses on the condensed consolidated statements of operations for the year ended December 31, 2020.

On December 15, 2020, the Company and Elevation reached an agreement through November 15, 2017regarding amendments to the gathering agreements and the settlement of all outstanding claims. As part of the settlement, the Company will pay Elevation $38.4 million in cash over 24 months, and Elevation submitted an unsecured claim of $80.0 million with the Bankruptcy Court. The agreement released certain areas from future dedication, provided a reduction in certain gathering fees, a reduction in the number of wells subject to the drilling commitment, and an unrelated third party for whichextended term in order to satisfy the remaining drilling commitment. The Company also relinquished the nominal common interest ownership it has paid $214.3had in Elevation. The Company previously accrued $46.8 million and is required$4.2 million of accrued interest related to paythe aforementioned alleged breach in contract. During the third quarter of 2020, the Company accrued an additional $12.2$68.7 million in April 2018,within liabilities subject to certain customary closing conditions, to lease a totalcompromise on the consolidated balance sheets and in reorganization items, net on the consolidated statements of approximately 36,600 net acres of undeveloped leasehold. Additionally, in January 2018, theoperations.

Company acquired approximately 1,200 net acres of undeveloped leasehold from an unrelated third party for $11.6 million, subject to certain customary closing conditions.

General
 
The Company is subject to contingent liabilities with respect to existing or potential claims, lawsuits, and other proceedings, including those involving environmental, tax, and other matters, certain of which are discussed more specifically below. The Company accrues liabilities when it is probable that future costs will be incurred and such costs can be reasonably estimated. Such accruals are based on developments to date and the Company’s estimates of the outcomes of these matters and its experience in contesting, litigating, and settling other matters. As the scope of the liabilities becomes better defined, there will be changes in the estimates of future costs, which management currently believes will not have a material effect on the Company’s financial position, results of operations, or cash flows.
 
As is customary in the oil and gas industry, the Company may at times have commitments in place to reserve or earn certain acreage positions or wells. If the Company does not meet such commitments, the acreage positions or wells may be lost or the Company may be required to pay damages if certain performance conditions are not met.

Litigation and Legal MattersItems

InThe Company is involved in various legal proceedings and reviews the ordinary coursestatus of business,these proceedings on an ongoing basis and, from time to time, may settle or otherwise resolve these matters on terms and conditions that management believes are in the Company’s best interests. The Company has provided the necessary estimated accruals in the consolidated balance sheets where deemed appropriate for litigation and legal related items that are ongoing and not yet concluded. Although the results cannot be known with certainty, the Company may at times be subject to claims and legal actions. Managementcurrently believes it is remote that the impactultimate results of such mattersproceedings will have a material adverse effect on the Company’s financial position, results of operations or cash flows. Management is unaware of any material pending litigation brought against the Company requiring the reserve of a contingent liability as of the date of this filing.

We were issued a Compliance Advisory in July 2015 from the Colorado Department of Public Health and Environment (“CDPHE”), which alleged air quality violations at certain of our facilities regarding leakages of volatile organic compounds from storage tanks, all of which were promptly addressed. On January 31, 2018, we entered into a Compliance Order on Consent with the CDPHE that provides for a field-wide administrative settlement of these issues.

The Compliance Order provides that we will implement changes to our design, operation, maintenance and recordkeeping of many of our field-wide storage tank systems to enhance our emissions management. Agreed upon and planned efforts include, but are not limited to, vapor control system modifications and verification, increased inspection and monitoring, and installation and operation of certain emission mitigation projects at certain facilities constructed in 2018 and 2019. The two primary elements of the Compliance Order are: (i) a monetary penalty of $138,600; and (ii) injunctive relief with an estimated cost of approximately $500,000, primarily representing capital enhancements to our operations. Certain expenditures for the injunctive relief have already been incurred prior to entry of the Compliance Order, with the remainder expected to be incurred over the next few years. We do not believe that the expenditures resulting from the settlement will have a material adverse effect on our consolidatedbusiness, financial statements.position, results of operations or liquidity.

Environmental. Due to the nature of the oil and natural gas industry, the Company is exposed to environmental risks. The Company has various policies and procedures to minimize and mitigate the risks from environmental contamination or with respect to environmental compliance issues. Liabilities are recorded when environmental damages resulting from past events are probable and the costs can be reasonably estimated. Except as discussed herein, the Company is not aware of any material environmental claims existing as of December 31, 2020 which have not been provided for or would otherwise have a material impact on the Company’s financial statements; however, there can be no assurance that current regulatory requirements will not change or that unknown potential past non-compliance with environmental laws, compliance matters or other environmental liabilities will not be discovered on our properties. The liability ultimately incurred with respect to a matter may exceed the related accrual.

COGCC Notices of Alleged Violations (“NOAVs”). The Company has received NOAVs from the Colorado Oil and Gas Conservation Commission (the “COGCC”) for alleged compliance violations that the Company has responded to. The Company does not believe penalties that could result from these NOAVs will have a material effect on its business, financial condition, results of operations or liquidity, but Extraction is in negotiations to settle all of its outstanding NOAVs with the COGCC, and the ultimate settlement amount is expected to exceed $600,000.

Oil, Natural Gas and NGL Reserve Quantities (Unaudited)
 
The reserves at December 31, 2017, 20162020, 2019 and 20152018 presented below were prepared by the independent engineering firm Ryder Scott Company, L.P. All reserves are located within the DJ Basin. Proved oil, natural gas and NGL reserves are the estimated quantities of oil, natural gas and NGL which geological and engineering data demonstrate, with reasonable certainty, to be recoverable in future years from known reservoirs under economic and operating conditions (i.e., prices and costs) existing at the time the estimate is made. Proved developed oil, natural gas and NGL reserves are proved reserves that can be expected to be recovered through existing wells and equipment in place and under operating methods being utilized at the time the estimates were made. The principal methodologies employed are decline curve analysis and analogy. The Company emphasizes that reserve estimates are inherently imprecise and that estimates of new discoveries and undeveloped locations are more imprecise than estimates of established proved producing oil and gas properties. Accordingly, these estimates are expected to change as future information becomes available.

For the year ended December 31, 2017,2020, the Company had upwarddownward revisions of previous estimates of 2,894.087,308 MBoe primarily due to revisions of PUD expirations due to the SEC’s five year drilling rule caused by the change in business strategy to focus on being cash flow positive rather than maximizing reserves growth. Additionally, downward revisions were due to altering the development plan to increase the spacing between wellbores, thus drilling fewer wells, as well as negative performance revisions. As a result of ongoing drilling and completion activities during 2020, the Company reported extensions, discoveries, and other additions of 13,545 MBoe. Additionally, during 2020 the Company sold reserves of 1,971 MBoe and purchased 0 reserves.
For the year ended December 31, 2019, the Company had downward revisions of previous estimates of 90,537 MBoe. As a result of ongoing drilling and completion activities during 2017,2019, the Company reported extensions, discoveries, and other additions of 56,487.935,191 MBoe. Additionally, during 20172019 the Company sold reserves of 6,773 MBoe and purchased reserves of 14,188.3746 MBoe.
 
For the year ended December 31, 2016,2018, the Company had downward revisions of previous estimates of 7,620.83,325 MBoe. As a result of ongoing drilling and completion activities during 2016,2018, the Company reported extensions, discoveries, and other additions of 56,698.582,733 MBoe. Additionally, during 20162018 the Company sold reserves of 10,167 MBoe and purchased reserves of 41,281.2 MBoe.
For the year ended December 31, 2015, the Company had upward revisions of previous estimates of 1,150.1 MBoe. These revisions are primarily the result of well performance exceeding previous estimates. As a result of ongoing drilling and completion activities during 2015, the Company reported extensions, discoveries, and other additions of 49,058.9 MBoe. Additionally, during 2015 the Company purchased reserves of 30,097.113,672 MBoe.
 
Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil, Natural Gas and NGL Reserves
 
The Company follows the guidelines prescribed in ASC 932, Extractive Activities-Oil and Gas for computing a standardized measure of future net cash flows and changes therein relating to estimated proved reserves. The following summarizes the policies used in the preparation of the accompanying oil, natural gas and NGL reserve disclosures, standardized measures of discounted future net cash flows from proved oil, natural gas and NGL reserves and the reconciliations of standardized measures from year to year.
 
The information is based on estimates of proved reserves attributable to the Company’s interest in oil and gas properties as of December 31 of the years presented. These estimates were prepared by Ryder Scott Company L.P., independent petroleum engineers.    
 
The standardized measure of discounted future net cash flows from production of proved reserves was developed as follows: (1) Estimates are made of quantities of proved reserves and future periods during which they are expected to be produced based on year-end economic conditions. (2) The estimated future cash flows are compiled by applying the trailing twelve monthtwelve-month average of the first of the month prices applied to the Company’s proved reserve year-end quantities. (3) The future cash flows are reduced by estimated production costs, costs to develop and produce the proved reserves and abandonment costs, all based on year-end economic conditions, plus Company overhead incurred. (4) Future net cash flows are discounted to present value by applying a discount rate of 10%.
 
The assumptions used to compute the standardized measure are those prescribed by the FASB and the SEC. These assumptions do not necessarily reflect the Company’s expectations of actual revenues to be derived from those reserves, nor their present value. The limitations inherent in the reserve quantity estimation process, as discussed previously, are equally applicable to the standardized measure computations, since these reserve quantity estimates are the basis for the valuation process. The Company emphasizes that reserve estimates are inherently imprecise and that estimates of new discoveries and undeveloped locations are more imprecise than estimates of established proved producing oil and gas properties. The standardized measure of discounted future net cash flows does not purport, nor should it be interpreted, to present the fair value of the Company’s oil and natural gas reserves. An estimate of fair value would also take into account, among other things, the recovery of reserves not presently classified as proved, anticipated future changes in prices and costs and a discount factor more representative of the time value of money and the risks inherent in reserve estimates.

(1)The Company’s calculations of the standardized measure of discounted future net cash flows does not include the effect of estimated future income tax expenses for the year ended December 31, 2015 as the Company was a limited liability company and not subject to income taxes. For the years ended December 31, 2017 and 2016, future income tax expenses in the Company’s calculation of the standardized measure of discounted future net cash flows are based on year-end statutory tax rates giving effect to the remaining tax basis in the oil and gas properties, other deductions, credit and allowances relating to the Company’s proved reserves. For purposes of the standardized measure calculation, it was assumed that all of the Company’s operations are attributable to the Company’s oil and gas assets. If the Company had been subject to entity-level income taxation, the unaudited pro forma future income tax expense at December 31, 2015 would have been $327.9 million and the unaudited standardized measure would have been $680.3 million.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

In accordance with the Securities Exchange Act, of 1934, as amended (the "Exchange Act"), Rules 13a-15(b) and 15d-15(b), we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2017.2020. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based upon that evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective as of December 31, 20172020 at the reasonable assurance level.

Remediation of a Previously Reported Material Weakness

During 2019, management determined that the Company did not design and maintain effective controls to determine the appropriate contract termination date and evaluate the potential accounting implications of changes in termination dates of contracts with customers. This material weakness resulted in a restatement of the Company’s condensed consolidated financial statements as of and for the three and nine month periods ended September 30, 2019 and immaterial errors to the consolidated financial statements for the periods ended December 31, 2018, March 31, 2019 and June 30, 2019. The line items affected were oil revenue, accounts payable and accrued liabilities, other non-current liabilities, inventory, prepaid expenses and other, and other non-current assets.

The Company and its Board are committed to maintaining a strong internal control environment. During 2020, management undertook a remediation plan to redesign and enhance existing controls to determine the appropriate contract termination date of new and amended revenue contracts and to evaluate the potential accounting implications of changes in termination dates of contracts with customers pursuant to the accounting treatment under ASC 606 - Revenue from Contracts with Customers. The remediation plan was implemented during 2020, and management determined that the enhancements to the design of our control activities related to determining the appropriate contract termination for contracts with customers have been satisfactorily implemented and have operated effectively for a sufficient period of time. Therefore, management concluded the previously reported material weakness is remediated as of December 31, 2020.

Management’s Annual Report on Internal Control over Financial Reporting

Our management, including our principal executive officer and principal financial officer, is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our consolidated financial statements for external purposes in accordance with generally accepted accounting principles. 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 risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.


OurAs of December 31, 2020, management assessed the effectiveness of the Company'sour internal control over financial reporting as of December 31, 2017, usingreporting. In making this assessment, management, including our principal executive officer and principal financial officer, used the criteria established in set forth by the Internal Control-IntegratedControl - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"(“COSO”). Based on this assessment, management determinedour principal executive officer and principal financial officer have concluded that our internal control over financial reporting was effective as of December 31, 2017.2020.
