Item 2.01	Completion of Acquisition or Disposition of Assets	
As previously disclosed in the Current Report on Form 8-K filed by Devon Energy Corporation on January 7, 2021 (the “Initial Form 8-K”), on January 7, 2021, East Merger Sub, Inc. (“Merger Sub”), a Delaware corporation and wholly owned, direct, subsidiary of Devon Energy Corporation, a Delaware corporation (“Devon” or the “Company”), completed its merger (the “Merger”) with and into WPX Energy, Inc., a Delaware corporation (“WPX”), as a result of which WPX became a wholly-owned, direct, subsidiary of the Company. The Merger was effected pursuant to the Agreement and Plan of Merger (the “Merger Agreement”), dated September 26, 2020, by and among the Company, Merger Sub and WPX.
This Amendment No. 1 to the Initial Form 8-K amends the Initial Form 8-K to include certain financial statements, certain pro forma financial information and certain other information. The WPX historical consolidated financial statements include amounts related to the Felix assets acquired on March 6, 2020. Due to immateriality, no adjustments are included in the Pro Forma Financial Statements to incorporate revenues and expenses for Felix prior to March 6, 2020. Except as provided herein, the disclosures made in the Initial Form 8-K remain unchanged.
 
Item 2.05	Costs Associated with Exit or Disposal Activates	
In conjunction with closing of the Merger, Devon anticipates that it will incur approximately $160 million to $200 million of restructuring and transaction costs, which are comprised of the following amounts:
 
 	•	 	Employee severance and termination benefits of $100 million to $125 million;	
 
 	•	 	Remaining merger transaction costs such as bank, legal and accounting fees of $50 million; and	
 
 	•	 	Contract termination and other office lease abandonment charges of approximately $10 million to $20 million.	
Devon expects to recognize the majority of these restructuring charges in the first quarter of 2021 and will recognize the remaining costs throughout 2021 as merger integration activities complete. Actual charges will vary if integration activities and related employee terminations do not occur as projected. Including approximately $85 million of employee retirement plan distributions triggered by the Merger previously included in Devon’s recorded balance sheet liabilities, Devon estimates that $220 million to $255 million of the estimated total costs will result in future cash expenditures. The majority of the costs that will not result in future cash expenditures consist of employee severance costs related to accelerated vesting of employee stock awards.

WPX Energy, Inc.
Consolidated Financial Statements (Audited)
For the fiscal year ended December 31, 2020

Report of Independent Auditors
Board of Directors of Devon Energy Corporation
We have audited the accompanying consolidated financial statements of WPX Energy, Inc. (the Company), which comprise the consolidated balance sheets as of December 31, 2020 and 2019, and the related consolidated statements of operations, changes in equity, and cash flows for the three years then ended, and the related notes to the consolidated financial statements.
Management’s Responsibility for the Financial Statements
Management is responsible for the preparation and fair presentation of these financial statements in conformity with U.S. generally accepted accounting principles; this includes the design, implementation and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free of material misstatement, whether due to fraud or error.
Auditor’s Responsibility
Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.
An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. Accordingly, we express no such opinion.
An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.
We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.
Opinion
In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of WPX Energy, Inc. at December 31, 2020 and 2019, and the consolidated results of their operations and their cash flows for the three years then ended in conformity with U.S. generally accepted accounting principles.

Notes to Consolidated Financial Statements
Note 1. Description of Business, Basis of Presentation and Summary of Significant Accounting Policies Description of Business
Operations of our company include oil, natural gas and natural gas liquids (“NGL”) development and production primarily located in Texas, New Mexico and North Dakota. We specialize in development and production from tight-sands and shale formations in the Delaware and Williston Basins. Associated with our commodity production are sales and marketing activities, referred to as commodity management activities, which include oil and natural gas purchased from third-party working interest owners in operated wells and the management of various commodity contracts, such as transportation.
The consolidated businesses represented herein as WPX Energy, Inc. is also referred to as “WPX,” the “Company,” “we,” “us” or “our.”
Merger with Devon Energy
On September 28, 2020 WPX and Devon Energy (“Devon”) announced the signing of an agreement (the “Merger Agreement”) to combine in an all-stock merger of equals transaction (the “Devon Merger”). The transaction was approved by the shareholders of both companies on December 30, 2020 and subsequently closed on January 7, 2021 (“Merger Close Date”). Under the terms of the agreement, WPX shareholders receive a fixed exchange ratio of 0.5165 shares of Devon common stock for each share of WPX common stock owned (the “Exchange Ratio”). After the exchange on the Merger Close Date, WPX became a wholly owned subsidiary of Devon. Merger related expenses of $11 million primarily related to legal and advisory fees are reflected in the Acquisition and merger costs on the Consolidated Statements of Operations. An additional $30 million of merger-related advisory costs became payable upon the successful closing of the Merger. The accompanying financial statements and footnotes reflect WPX prior to the Devon Merger.
Basis of Presentation and Summary of Significant Accounting Policies
Principles of consolidation
The consolidated financial statements include the accounts of our wholly and majority-owned subsidiaries and investments. Companies in which we own 20 percent to 50 percent of the voting common stock, or otherwise exercise significant influence over operating and financial policies of the Company, are accounted for under the equity method. All material intercompany transactions have been eliminated. The Company has no other elements of comprehensive income (loss) other than net income (loss).
Our continuing operations comprise a single business segment, which includes the development, production and commodity management activities of oil, natural gas and NGLs in the United States.
Discontinued Operations
See Note 3 for a further discussion of discontinued operations. Unless indicated otherwise, the information in the Notes to Consolidated Financial Statements relates to continuing operations.
Use of estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
Significant estimates and assumptions that impact these financials include:
 
 	•	 	impairment assessments of long-lived assets;	
 
 	•	 	valuation of deferred tax assets and liabilities;	
 
 	•	 	valuations of derivatives;	
 
 	•	 	estimation of oil and natural gas reserves; and	
 
 	•	 	assessments of litigation-related contingencies.	
These estimates are discussed further throughout these notes.

WPX Energy, Inc.
Notes to Consolidated Financial Statements-(Continued)
 
Cash and cash equivalents
Our cash and cash equivalents balance includes amounts primarily invested in funds with high-quality, short-term securities and instruments that are issued or guaranteed by the U.S. government. These have maturity dates of three months or less when acquired.
Restricted cash
Restricted cash was approximately $23 million and $20 million as of December 31, 2020 and 2019, respectively, and is included in other current assets on the Consolidated Balance Sheets.
Accounts receivable
Accounts receivable are carried on a gross basis, with no discounting, less the allowance for credit losses. We estimate the allowance for credit losses based on existing economic conditions, the financial conditions of the customers and the amount and age of past due accounts. Receivables are considered past due if full payment is not received by the contractual due date. Past due accounts are generally written off against the allowance for credit losses only after all collection attempts have been exhausted. A portion of our receivables are from joint interest owners of properties we operate. Thus, we may have the ability to withhold future revenue disbursements to recover any non-payment of joint interest billings.
Inventories
All inventories are stated at the lower of cost or market. Our materials, supplies and other inventories consist of tubular goods and production equipment for future transfer to wells and crude oil production in transit. Inventory is recorded and relieved using the weighted average cost method. The following table presents a summary of inventories.

	  	$	24	 	  	$	41	 	
	  	 	 	 	  	 	 	 	
During the first quarter of 2020, we recorded a lower-of-cost or market adjustment to material and supplies inventory of approximately $13 million which is reported in Other—net on the Consolidated Statement of Operations.
Properties and equipment
Oil and gas exploration and production activities are accounted for under the successful efforts method. Costs incurred in connection with the drilling and equipping of exploratory wells are capitalized as incurred. If proved reserves are not found, such costs are charged to exploration expenses. Other exploration costs, including geological and geophysical costs and lease rentals are charged to expense as incurred. All costs related to development wells, including related production equipment and lease acquisition costs, are capitalized when incurred whether productive or nonproductive.
Unproved properties include lease acquisition costs. Individually significant lease acquisition costs are assessed annually, or as conditions warrant, for impairment considering our future drilling plans, the remaining lease term and recent drilling results. Lease acquisition costs that are not individually significant are aggregated by prospect or geographically, and the portion of such costs estimated to be nonproductive prior to lease expiration is amortized over the average holding period. The estimate of what could be nonproductive is based on our historical experience or other information, including current drilling plans and existing geological data. Impairment and amortization of lease acquisition costs are included in exploration expense on the Consolidated Statements of Operations. If the unproved properties are determined to be productive, the appropriate related costs are transferred to proved oil and gas properties. We refer to unproved lease acquisition costs as unproved properties.
From time to time we may exchange leasehold acreage with third parties. In connection with this type of nonmonetary exchange in which commercial substance is established, we must record assets received based on the fair value of either the asset surrendered or, if more readily determinable, the assets received. Any resulting difference between the fair value and the carrying value of the assets is recorded as a gain or loss, to the extent a loss exceeds accumulated amortization, in the Consolidated Statements of Operations.
Gains or losses from the ordinary sale or retirement of properties and equipment are recorded in operating income (loss) as either a separate line item, if individually significant, or included in other—net on the Consolidated Statements of Operations.

WPX Energy, Inc.
Notes to Consolidated Financial Statements-(Continued)
 
Costs related to the construction or acquisition of field gathering, processing and certain other facilities are recorded at cost. Ordinary maintenance and repair costs are expensed as incurred.
Depreciation, depletion and amortization
Capitalized exploratory and developmental drilling costs, including lease and well equipment and intangible development costs are depreciated and amortized using the units-of-production method based on estimated proved developed oil and gas reserves on a field basis. Depletion of producing leasehold costs is based on the units-of-production method using estimated total proved oil and gas reserves on a field basis. In arriving at rates under the units-of-production methodology, the quantities of proved oil and gas reserves are established based on estimates made by our geologists and engineers.
Costs related to gathering, processing and certain other facilities are depreciated on the straight-line method over the estimated useful lives.
Impairment of long-lived assets
We evaluate our long-lived assets for impairment when events or changes in circumstances indicate, in our management’s judgment, that the carrying value of such assets may not be recoverable. When an indicator of impairment has occurred, we compare our management’s estimate of undiscounted future cash flows attributable to the assets to the carrying value of the assets to determine whether an impairment has occurred. If an impairment of the carrying value has occurred, we determine the amount of the impairment recognized in the financial statements by estimating the fair value of the assets and recording a loss for the amount that the carrying value exceeds the estimated fair value.
Proved properties, including developed and undeveloped, are assessed for impairment using estimated future undiscounted cash flows on a field basis. If the undiscounted cash flows are less than the book value of the assets, then a subsequent analysis is performed using discounted cash flows. Additionally, our leasehold costs are evaluated for impairment if the proved property costs within a basin are impaired.
Judgments and assumptions are inherent in our management’s estimate of undiscounted future cash flows and an asset’s fair value. These judgments and assumptions include such matters as the estimation of oil and gas reserve quantities, risks associated with the different categories of oil and gas reserves, the timing of development and production, expected future commodity prices, capital expenditures, production costs, and appropriate discount rates.
Contingent liabilities
Due to the nature of our business, we are routinely subject to various lawsuits, claims and other proceedings. We recognize a liability in our consolidated financial statements when we determine that it is probable that a loss has been incurred and the amount can be reasonably estimated. If we determine that a loss is probable but lack information on which to reasonably estimate a loss, if any, or if we determine that a loss is only reasonably possible, we do not recognize a liability. We disclose the nature of loss contingencies that are potentially material but for which no liability has been recognized.
Asset retirement obligations
We record an asset and a liability upon incurrence equal to the present value of each expected future asset retirement obligation (“ARO”). These estimates include, as a component of future expected costs, an estimate of the price that a third party would demand, and could expect to receive, for bearing the uncertainties inherent in the obligations, sometimes referred to as a market risk premium. The ARO asset is depreciated in a manner consistent with the depreciation of the underlying physical asset. We measure changes in the liability due to passage of time by applying an interest method of allocation. This amount is recognized as an increase in the carrying amount of the liability and as a corresponding accretion expense in lease and facility operating expense included in costs and expenses.
Cash flows from revolving credit facilities
Proceeds and payments related to any borrowings under a revolving credit facility are reflected in the financing activities of the Consolidated Statements of Cash Flows on a gross basis.
Derivative instruments and hedging activities
We utilize derivatives to manage our commodity price risk. These instruments consist primarily of futures contracts, swap agreements, option contracts, and forward contracts involving short- and long-term purchases and sales of a physical energy commodity.

WPX Energy, Inc.
Notes to Consolidated Financial Statements-(Continued)
 
We report the fair value of derivatives, except those for which the normal purchases and normal sales exception has been elected, on the Consolidated Balance Sheets in derivative assets and derivative liabilities as either current or noncurrent. We determine the current and noncurrent classification based on the timing of expected future cash flows of individual trades. We report these amounts on a gross basis. Additionally, we report cash collateral receivables and payables with our counterparties on a gross basis.
The accounting for the changes in fair value of a commodity derivative can be summarized as follows:

Derivative Treatment	  	Accounting Method	
Normal purchases and normal sales exception	  	Accrual accounting	
Designated in a qualifying hedging relationship	  	Hedge accounting	
All other derivatives	  	Mark-to-market accounting	
We may elect the normal purchases and normal sales exception for certain short- and long-term purchases and sales of a physical energy commodity. Under accrual accounting, any change in the fair value of these derivatives is not reflected on the balance sheet after the initial election of the exception.
Certain gains and losses on derivative instruments included on the Consolidated Statements of Operations are netted together to a single net gain or loss, while other gains and losses are reported on a gross basis. Gains and losses recorded on a net basis include:
 
 	•	 	unrealized gains and losses on all derivatives that are not designated as cash flow hedges related to production and for which we have not elected the normal purchases and normal sales exception;	
 
 	•	 	unrealized gains and losses on all derivatives that are not designated as cash flow hedges related to commodity management and for which we have not elected the normal purchases and normal sales exception;	
 
 	•	 	realized gains and losses on all derivatives that settle financially;	
 
 	•	 	realized gains and losses on derivatives held for trading purposes; and	
 
 	•	 	realized gains and losses on derivatives entered into as a pre-contemplated buy/sell arrangement.	
Realized gains and losses on derivatives that require physical delivery are recorded on a gross basis. In reaching our conclusions on this presentation, we considered whether we act as principal in the transaction; whether we have the risks and rewards of ownership, including credit risk; and whether we have latitude in establishing prices.
Product and commodity management revenues
Our revenues on the Consolidated Statement of Operations include oil, natural gas and natural gas liquids sales (collectively, “product revenues”), commodity management revenues and net gain (loss) on derivatives. Product revenues relate to production from properties in which we own an interest. Commodity management revenues primarily relate to sales of products we may purchase from other third parties in the areas we operate. We derive substantially all of our revenues from the sale of oil, natural gas and natural gas liquids in the continental United States. We believe the disaggregation of product revenues into the three major product types of oil sales, natural gas sales and natural gas liquid sales is an appropriate level of detail for our company’s primary activity and industry.
Our contracts for oil and natural gas sales are typically standard industry contracts that may include modifications for counterparty-specific provisions related to volumes, price differentials, discounts and other adjustments and deductions. Our contracts related to natural gas liquids sales are generally with the company contracted to gather and process natural gas to extract the natural gas liquids. The provider of these services typically purchases our share of the natural gas liquids pursuant to the terms of each contract. Oil, natural gas and natural gas liquids prices are derived from stated market prices which are then adjusted to reflect deductions including fuel, shrink, transportation, fractionation and processing. Product revenues are initially accrued based on volume and price estimates using the best available information. These accruals are typically actualized one to two months later when volume and pricing are confirmed. Adjustments to actualize the accruals for product revenues are generally not material.
Revenue is recognized when the performance obligations under the terms of our contracts with customers are satisfied. The primary performance obligation for the material portion of our revenue contracts is the delivery of oil, natural gas or natural gas liquids to our customers. Significant judgments related to revenue recognition include principal versus agent considerations.
We record revenue on a gross basis when we control a promised good or service before transferring it to a customer. We record revenue on a net basis when we arrange for another company to provide the good or service. Determining the point and time when control of a product transfers to a customer requires significant judgment. Payment is typically due 30 to 45 days following delivery of product to our customers.

WPX Energy, Inc.
Notes to Consolidated Financial Statements-(Continued)
 
Commodity management expenses
Commodity management expenses primarily relate to product we may purchase from other third parties in the areas we operate.
Income taxes
We file consolidated and combined federal and state income tax returns for the Company and its subsidiaries. We record deferred taxes for the differences between the tax and book basis of our assets as well as loss or credit carryovers to future years. A valuation allowance is established to reduce deferred tax assets if it is determined it is more likely than not that the related tax benefit will not be realized. Deferred tax liabilities and assets are classified as noncurrent on the statement of financial position.
Employee stock-based compensation
Restricted stock units and awards are generally valued at market value on the grant date and generally vest over three years. Restricted stock compensation cost, net of estimated forfeitures, is generally recognized over the vesting period on a straight-line basis. Performance-based awards are tied to shareholder return over time relative to our peer group and are valued using a Monte Carlo method using measures of total shareholder return.
Earnings (loss) per common share
Basic earnings (loss) per common share is based on the sum of the weighted-average number of common shares outstanding and vested restricted stock units. Diluted earnings (loss) per common share includes any dilutive effect of stock options and nonvested restricted stock units and awards (see Note 4).
Debt issuance costs
Debt issuance fees, which are recorded at cost, net of amortization, are amortized over the life of the respective debt agreements utilizing the effective interest and straight-line methods. The Company had total net debt issuance costs of $49 million and $36 million as of December 31, 2020 and 2019, respectively. Unamortized debt issuance costs related to the Company’s senior unsecured notes are reported in long-term debt (see Note 9) and debt issuance costs related to the Credit Facility are recorded in other noncurrent assets on the Company’s Consolidated Balance Sheets.
Recently Adopted Accounting Standards
In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments—Credit Losses. This ASU, as further amended, affects trade receivables, financial assets and certain other instruments that are not measured at fair value through net income and requires entities to recognize an estimated credit loss expected over the life of an exposure through an allowance, which is re-measured at each reporting date. This ASU requires entities to consider a broader range of information when estimating expected credit losses, including current information and reasonable forecasts, which may result in the earlier recognition of losses. We applied this ASU effective January 1, 2020 using a modified retrospective approach. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.
In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements. Entities are no longer required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but public companies are required to disclose additional information about significant unobservable inputs for Level 3 measurements. The adoption of this ASU, effective January 1, 2020, did not have a material impact on the Company’s consolidated financial statements.
Accounting Standards Not Yet Adopted
In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU simplifies various aspects related to accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and clarifying and amending existing guidance to improve consistent application. The amendments in this ASU are effective for public entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2020. The Company is evaluating the impact of the adoption of ASU 2019-12 on its financial statements, but does not expect such adoption to have a material impact.

Note 2. Felix Acquisition
On December 15, 2019, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with Felix Investments Holdings II, LLC (“Felix Parent”) to acquire all of the issued and outstanding membership interests of Felix Energy Holdings II, LLC (“Felix”) (collectively, the “Felix Acquisition”), for consideration of approximately $2.5 billion (the “Unadjusted Purchase Price”), consisting of $900 million in cash (the “Unadjusted Cash Purchase Price”), and approximately 153 million unregistered shares of our common stock (the “Unadjusted Equity Consideration”) determined by dividing $1.6 billion by $10.46, the volume weighted average per share price of the Company for the ten consecutive trading days ending on December 13, 2019. We completed the Felix Acquisition on March 6, 2020 (the “Acquisition Date”). The estimated fair value of the consideration was $1.933 billion, consisting of the estimated fair value of the 153 million shares of WPX common stock and approximately $939 million in cash. The consideration was subject to closing adjustments and the cash consideration was increased due to interim operations and working capital items. We have incurred approximately $30 million of acquisition-related costs, primarily related to legal and advisory fees which are reflected on a separate line item on the Consolidated Statements of Operations. WPX funded the cash consideration with proceeds from a debt offering in January 2020 along with available cash on hand and borrowings under our revolving credit facility. See Note 9 for further discussion on the financing of this transaction.
All of Felix’s properties are located in the Delaware Basin and include approximately 58,000 net acres with six productive benches, with core operations located in Loving, Reeves, Ward and Winkler counties in Texas. As of closing, proved developed reserves were approximately 106 MMBoe.
The following table presents the unaudited pro forma financial results for the twelve months ended December 31, 2020 and 2019 as if the Felix Acquisition and related financings had been completed January 1, 2019. In addition, the twelve months ended December 31, 2020 have been adjusted to exclude $30 million of acquisition-related costs. The unaudited pro forma financial information does not purport to be indicative of results of operations that would have occurred had the Felix Acquisition occurred on the date assumed or for the periods presented, nor is such information indicative of the Company’s expected future results of operations.

Net income (loss) from continuing operations attributable to WPX Energy, Inc.	  	$	(820	) 	 	$	429	 	
The Felix Acquisition qualified as a business combination, and as a result, we must estimate the fair value of the underlying shares distributed as consideration, the assets acquired and the liabilities assumed as of the Acquisition Date. The fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements also utilize assumptions of market participants. We used a combination of market data and discounted cash flow models in determining the fair value of the oil and gas properties. The discounted cash flow models include estimates and assumptions representative of the economic conditions that existed at the Acquisition Date, such as future commodity prices, projections of estimated quantities of oil and natural gas reserves, expectations for timing and amount of future development and operating costs, projections of future rates of production, expected recovery rates and risk adjusted discount rates. These assumptions represent Level 3 inputs.
The initial accounting for the Felix Acquisition is preliminary and adjustments to provisional amounts for properties and equipment, certain accrued receivables and liabilities and related deferred taxes, if any, or recognition of additional assets acquired or liabilities assumed may occur as additional information is obtained about facts and circumstances that existed at the Acquisition Date. Such adjustments could result in the recognition of goodwill which would be subject to impairment review. To calculate the fair value of the WPX common stock consideration, we used the closing price of $6.50 per share on March 6, 2020. The following table summarizes the consideration paid for the Felix Acquisition and the preliminary estimates of fair value of the assets acquired and liabilities assumed as of the Acquisition Date. We used several different pricing scenarios for future commodity prices and a range of risk-adjusted discount rates from 10 percent to 25 percent, which are subject to change.

Note 3. Discontinued Operations
In first-quarter 2018, we sold our properties in the San Juan Basin’s Gallup oil play and we received approximately $667 million. In addition, the purchaser assumed approximately $309 million of gathering and processing commitments that conclude in 2026; however, WPX left in place a performance guarantee with respect to these commitments. At the time of sale in 2018, we believed that any future performance under this guarantee obligation was unlikely. As part of the divestiture, we determined the fair value of the guarantee that was provided. We estimated the fair value of the guarantee to be approximately $9 million based on the factors mentioned above along with projections of estimated future volume throughputs and risk adjusted discount rates, all of which are Level 3 inputs. This amount is included in our calculation of the loss on sale. We recorded a total loss on the sale of $147 million in 2018.
In first-quarter 2020, we were notified that the purchaser would not remit full payment of the deficiency due to the gatherer for the recently ended contract year. As a result, we recorded a $22 million accrual in first-quarter 2020 for the net amount of our portion of the deficiency payment due in 2020. This payment was made in April 2020. The remaining commitment for future contract years through 2026 is approximately $231 million. In first-quarter 2020, we also accrued an additional $162 million, related to our estimated potential exposure based on a probability-based cash flow for the remainder of the contract term. Of the $162 million, $126 million is included in other noncurrent liabilities and $36 million is included in accrued and other current liabilities on the Consolidated Balance Sheets as of December 31, 2020.
Our income (loss) from discontinued operations consist of the items related to previously owned properties in the San Juan Basin and accretion on certain transportation and gathering obligations retained and recognized in prior years related to the sale of Powder River properties. See Note 11 for additional information related to the Powder River liabilities.

Note 5. Impairment, Equity Method Investment Transactions, Exploration Expenses and Other
Impairment of proved properties
As a result of the significant decline in forward crude prices, primarily driven by the current economic environment resulting from the COVID-19 pandemic during the first quarter of 2020, we performed impairment assessments of our proved properties in the Delaware and Williston Basins. As a result, we recorded a $967 million impairment of proved properties in the Williston Basin during the first quarter of 2020. Our impairment analyses and assessment included undiscounted and discounted future cash flows, as applicable, which considered information obtained from drilling, other activities and reserve quantities (see Note 16).
Equity Method Investment Transactions
During the first quarter of 2019, we closed on the sale of our 20 percent equity interest in the Whitewater natural gas pipeline. The net book value of this equity method investment at the time of disposition was approximately $15 million. As a result of this transaction, we recorded a $126 million gain in 2019.
During the second quarter of 2019, we received a distribution of approximately $357 million related to our 25 percent equity interest in the Oryx pipeline partnership after the underlying assets were sold. The net book value of this equity method investment was approximately $110 million as of the closing date. As a result of this transaction, we recorded a gain of $247 million in 2019.
Exploration Expenses
The following table presents a summary of exploration expenses.

Other
Commodity management expense for the year ended December 31, 2020 includes a lower-of-cost or market adjustment related to long-term line fill, included in other noncurrent assets on the Consolidated Balance Sheet, of approximately $8 million.
For the year ended December 31, 2020, we recognized gains in conjunction with exchanges of leasehold of approximately $27 million which are included in other (income) expense—net on the Consolidated Statement of Operations.
In third-quarter 2019, we recorded an $11 million charge included in other-net on the Consolidated Statements of Operations associated with an offer made by us to settle certain contractual disputes in the Williston Basin. The offer is still pending.
Note 6. Investments
Catalyst Midstream Partners, LLC
In June 2017, we signed an agreement with Howard Energy Partners (“Howard”) to jointly develop oil gathering and natural gas processing infrastructure in the Stateline area of the Delaware Basin. Under the terms of the agreement, WPX and Howard each have a 50 percent voting interest in the joint venture legal entity, Catalyst Midstream Partners LLC (“Catalyst”), and a Howard entity serves as operator. We account for our investment in Catalyst as an equity method investment. In connection with the joint venture formation, a consolidated subsidiary of WPX dedicated production from its current and future leasehold interest in the Stateline area, representing 50,000 net acres in the Delaware Basin, pursuant to 20 year fixed-fee oil gathering and natural gas processing agreements with subsidiaries of Catalyst. The agreements do not include any minimum volume commitments. As of December 31, 2020, the difference in our investment and our underlying equity in the net assets of Catalyst was approximately $238 million. In 2017, we deferred recognition of the $349 million of cash we received at closing and will recognize it over the 20 years based on production volumes as a deduction to gathering, processing and transportation expense. As of December 31, 2020, the deferred amount was $330 million of which $320 million is reported within other noncurrent liabilities on the Consolidated Balance Sheet.

Notes to Consolidated Financial Statements-(Continued)
 
On February 12, 2021 Devon Energy redeemed all of the 6.000% Senior Notes due 2022.
On June 3, 2020, we completed a debt offering of $500 million of 5.875% Senior Notes due 2028 (the “2028 Notes”). The notes are senior unsecured obligations ranking equally with the Company’s other existing and future senior unsecured indebtedness. The 2028 Notes bear interest at a rate of 5.875% per annum and were priced at 100.0% of par. Interest is payable on notes semiannually in arrears on June 15 and December 15 of each year commencing on December 15, 2020. The 2028 Notes will mature on June 15, 2028. At any time prior to June 15, 2023, the Company may, on one or more occasions and subject to certain conditions described in the Indenture, redeem up to 35% of the aggregate principal amount of the Notes at a redemption price equal to 105.875% of the principal amount of the Notes redeemed with an amount of cash not greater than the net proceeds that the Company raises in certain equity offerings, as described in the Indenture. The Company also has the option, at any time prior to June 15, 2023, on one or more occasions, to redeem some or all of the Notes at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus a specified “make whole” premium as described in the Indenture. At any time on or after June 15, 2023, the Company may, on one or more occasions, redeem the Notes, in whole or in part, at the applicable redemption prices set forth in the Indenture. The Indenture contains covenants that, among other things, restrict the Company’s ability to grant liens on its assets and merge, consolidate or transfer or lease all or substantially all of its assets, subject to certain qualifications and exceptions. The net proceeds from the offering of the 2028 Notes were approximately $491 million and approximately $9 million of debt issuance costs were capitalized.
In conjunction with the offering of the 2028 Notes, we launched a tender offer for a portion of our 2022 Notes, 2023 Notes and 2024 Notes. On July 2, 2020, we closed on the purchase of $369 million aggregate principal amount for our 2022 Notes, 2023 Notes and 2024 Notes through cash tender offers. We recorded a $24 million loss on extinguishment of debt in third-quarter 2020.
On January 10, 2020, we completed a debt offering of $900 million aggregate principal amount of 4.50% Senior Notes due 2030 (the “2030 Notes”). The notes are senior unsecured obligations ranking equally with the Company’s other existing and future senior unsecured indebtedness. The 2030 Notes bear interest at a rate of 4.50% per annum and were priced at 100.0% of par. Interest is payable on the notes semiannually in arrears on January 15 and July 15 of each year commencing on July 15, 2020. The 2030 Notes will mature on January 15, 2030. At any time prior to January 15, 2023, the Company may, on one or more occasions and subject to certain conditions described in the Indenture, redeem up to 35% of the aggregate principal amount of the Notes at a redemption price equal to 104.5% of the principal amount of the Notes redeemed with an amount of cash not greater than the net proceeds that the Company raises in certain equity offerings, as described in the Indenture. The Company also has the option, at any time prior to January 15, 2025, on one or more occasions, to redeem some or all of the Notes at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus a specified “make whole” premium as described in the Indenture. At any time on or after January 15, 2025, the Company may, on one or more occasions, redeem the Notes, in whole or in part, at the applicable redemption prices set forth in the Indenture. The Indenture contains covenants that, among other things, restrict the Company’s ability to grant liens on its assets and merge, consolidate or transfer or lease all or substantially all of its assets, subject to certain qualifications and exceptions. The net proceeds from the offering of the 2030 Notes were approximately $886 million and approximately $14 million of debt issuance costs were capitalized. The net proceeds from this offering were used to fund a portion of the Felix Acquisition.
On September 24, 2019, we completed a debt offering of $600 million of 5.250% Senior Notes due in 2027 (the “2027 Notes”). The notes are senior unsecured obligations ranking equally with the Company’s other existing and future senior unsecured indebtedness. Interest is payable on the notes semiannually in arrears on April 15 and October 15 of each year commencing on April 15, 2020. The 2027 Notes will mature on October 15, 2027 with the option, prior to October 15, 2022, to redeem some or all of the notes at a specified “make whole” premium as described in the indenture governing the notes or, at any time on or after October 15, 2022, we have the option to redeem the notes, in whole or in part, at the applicable redemption prices set forth in the indenture. The net proceeds from the offering of the 2027 Notes were approximately $592.5 million and approximately $2 million of debt issuance costs were capitalized.
The net proceeds from this offering were used to fund the purchase of $550 million aggregate principal amount of our 2022 Notes and 2023 Notes through cash tender offers. As a result of the debt tender offers, we recorded a loss on extinguishment of debt of $47 million, which includes approximately $44 million of premium and approximately $3 million write-off of previously capitalized costs.
In the second quarter of 2018, we used proceeds from our San Juan Gallup disposition and the issuance of new senior notes discussed below to retire $921 million aggregate principal amount of our senior notes ($350 million due 2020 and $571 million due 2022) through a series of cash tender offers. As a result of the debt tender offers, we recorded a loss on extinguishment of debt of $71 million, which includes approximately $63 million of premium and approximately $6 million write-off of previously capitalized costs.
The terms of the indentures governing our 2022 Notes, 2023 Notes, 2024 Notes, 2026 Notes, 2027 Notes, 2028 Notes and 2030 Notes are substantially identical.

Change of Control. If we experience a change of control (as defined in the indentures governing the notes) accompanied by a specified rating decline, we must offer to repurchase the notes of such series at 101% of their principal amount, plus accrued and unpaid interest.
Covenants. The terms of the indentures governing our notes restrict our ability and the ability of our subsidiaries to incur additional indebtedness secured by liens and to effect a consolidation, merger or sale of substantially all our assets. The indentures also require us to file with the trustee and the SEC certain documents and reports within certain time limits set forth in the indentures. However, these limitations and requirements are subject to a number of important qualifications and exceptions. The indentures do not require the maintenance of any financial ratios or specified levels of net worth or liquidity.
Events of Default. Each of the following is an “Event of Default” under the indentures with respect to the notes of any series:
 
 	(1)	a default in the payment of interest on the notes when due that continues for 30 days;	
 
 	(2)	a default in the payment of the principal of or any premium, if any, on the notes when due at their stated maturity, upon redemption, or otherwise;	
 
 	(3)	failure by us to duly observe or perform any other of the covenants or agreements (other than those described in clause (1) or (2) above) in the indenture, which failure continues for a period of 60 days, or, in the case of the reporting covenant under the indenture, which failure continues for a period of 90 days, after the date on which written notice of such failure has been given to us by the trustee; provided, however, that if such failure is not capable of cure within such 60-day or 90-day period, as the case may be, such 60-day or 90-day period, as the case may be, will be automatically extended by an additional 60 days so long as (i) such failure is subject to cure and (ii) we are using commercially reasonable efforts to cure such failure; and	
 
 	(4)	certain events of bankruptcy, insolvency or reorganization described in the indenture.

On March 27, 2020, the President of the United States signed into law the Coronavirus Aid, Relief, and Economic Security Act, H.R. 748 (“CARES Act”). The CARES Act includes modifications to the Internal Revenue Code (“IRC”) intended to provide economic relief to those impacted by the COVID-19 pandemic such as allowing taxpayers to accelerate the return of any remaining balance of alternative minimum tax (“AMT”) credit carryforwards. The income tax effects of changes in tax laws are recognized in the period enacted. As a result, the Company has received all remaining AMT credits as of December 31, 2020. However, our AMT credits are subject to change based on the results of the 2011 Williams audit as discussed below and may impact our refunds already received.
The following table provides reconciliations from the provision (benefit) for income taxes from continuing operations at the federal statutory rate to the realized provision (benefit) for income taxes.

As discussed below, we recorded valuation allowances on certain federal and state net operating loss (“NOL”) carryovers generated in current years.
Significant changes to our operations during 2020, 2019 and 2018 resulted in changes to our anticipated future state apportionment for our estimated state deferred tax liability. As a result of these changes and the differing state tax rates, we recorded an additional $6 million, $10 million and $5 million deferred tax benefit in 2020, 2019 and 2018, respectively.
The following table includes significant components of deferred tax liabilities and deferred tax assets.

Net cash payments (receipts) for income taxes, including AMT credit carryforward refunds, were $(39) million, $(38) million and $2 million in 2020, 2019 and 2018, respectively.
The Company has federal NOL carryovers of approximately $2.5 billion at December 31, 2020, including a $218 million NOL acquired in 2015 (“RKI NOL”), that will not begin to expire until 2032.

WPX Energy, Inc.
Notes to Consolidated Financial Statements-(Continued)
 
The Company has state NOL carryovers of approximately $4.9 billion and $4.2 billion at 2020 and 2019, respectively, of which more than 99 percent expire after 2029.
We have recorded valuation allowances against deferred tax assets attributable primarily to federal and state NOL carryovers. When assessing the need for a valuation allowance, we primarily consider future reversals of existing taxable temporary differences. To a lesser extent we may also consider future taxable income exclusive of reversing temporary differences and carryovers, and tax-planning strategies that would, if necessary, be implemented to accelerate taxable amounts to utilize expiring carryovers. The ultimate amount of deferred tax assets realized could be materially different from those recorded, as influenced by future operational performance, potential changes in jurisdictional income tax laws and other circumstances surrounding the actual realization of related tax assets. Valuation allowances that we have recorded are due to our expectation that we will not have sufficient income, or income of a sufficient character, in those jurisdictions to which the associated deferred tax asset applies. Additional valuation allowances against our NOL carryovers may be required in future periods if additional losses are incurred or other circumstances change.
The ability of WPX to utilize loss carryovers to reduce future federal taxable income and income tax could be subject to limitations under the Internal Revenue Code. The utilization of such carryovers may be limited upon the occurrence of certain ownership changes during any three year period resulting in an aggregate change of more than 50 percent in beneficial ownership (an “Ownership Change”). As of December 31, 2020, we do not believe that an Ownership Change has occurred for WPX, but an Ownership Change did occur for our RKI acquisition in 2015. Therefore, there is an annual limitation on the benefit that WPX can claim from RKI NOL that arose prior to the acquisition.
Pursuant to our tax sharing agreement with The Williams Companies (“Williams”), we remain responsible for the tax from audit adjustments related to our business for periods prior to our spin-off from Williams on December 31, 2011. The 2011 consolidated tax filing by Williams is currently being audited by the IRS and is the only pre spin-off period for which we continue to have exposure to audit adjustments as part of Williams. The IRS has proposed an adjustment related to our business for which a payment to Williams could be required. We have evaluated the issue and are in the process of protesting the adjustment within the normal Appeals process of the IRS. In addition, the AMT credit carryforward deferred tax asset that was allocated to us by Williams at the time of the spin-off could change due to audit adjustments unrelated to our business. Any such adjustments to this allocated deferred tax asset will not be known until the IRS examination is completed but is not expected to result in a cash settlement with Williams. However, if the Company has to amend filed returns whereby refunds of AMT credit carryforwards have been received, the Company may have to remit cash to the IRS. Through December 31, 2020, we have received approximately $83 million related to these AMT credit carryforwards.
The Company files a consolidated federal income tax return and several state income tax returns. The Company’s federal income tax returns for tax years 2014 through 2019 remain open for examination. The statute of limitations for most states expires one year after expiration of the IRS statute. During the year ended December 31, 2017, the IRS began an examination of the Company’s 2014, 2015 and 2016 federal income tax returns. In addition, the IRS began an examination of RKI’s 2014 and short-period 2015 federal income tax returns. These examinations were resolved during 2020 with no adjustments.
The Company’s policy is to recognize related interest and penalties as a component of income tax expense. The amounts accrued for interest and penalties are approximately $1 million or less for 2020, 2019 and 2018. The impact of this accrual is included within Other in our reconciliation of the provision (benefit) at statutory rate to recorded provision (benefit) for income taxes.
As of December 31, 2020, the Company has approximately $10 million of unrecognized tax benefits, which is offset by an increase in deferred tax assets of approximately $5 million. During the next 12 months, we do not expect ultimate resolution of any uncertain tax position that would result in a significant increase or decrease of an unrecognized tax benefit.
Note 11. Contingent Liabilities and Commitments
Contingent Liabilities
Federal gas royalties
Other producers have been pursuing administrative appeals with a federal regulatory agency and have been in discussions with a state agency in New Mexico regarding certain deductions, comprised primarily of processing, treating and transportation costs, used in the calculation of royalties. Although we are not a party to those matters, we are monitoring them to evaluate whether their resolution might have the potential for unfavorable impact on our results of operations. Certain outstanding issues in those matters could be material to us. We received notice from the U.S. Department of Interior Office of Natural Resources Revenue (“ONRR”) in the fourth quarter of 2010, intending to clarify the guidelines for calculating federal royalties on conventional gas production applicable to many of our federal leases in New Mexico. The guidelines for New Mexico

WPX Energy, Inc.
Notes to Consolidated Financial Statements-(Continued)
 
properties were revised slightly in September 2013 as a result of additional work performed by the ONRR. The revisions did not change the basic function of the original guidance. The ONRR’s guidance provides its view as to how much of a producer’s bundled fees for transportation and processing can be deducted from the royalty payment. We believe using these guidelines would not result in a material difference in determining our historical federal royalty payments for our leases in New Mexico. Similar guidelines were subsequently issued for certain leases in Colorado and, as in the case of the New Mexico guidelines, we do not believe that they will result in a material difference to our historical federal royalty payments. ONRR has asked producers to attempt to evaluate the deductibility of these fees directly with the midstream companies that transport and process gas.
Environmental matters
Our operations are subject to numerous federal, state, local, Native American tribal and foreign laws and regulations governing the discharge of materials into the environment or otherwise relating to environmental protection. Failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal fines and penalties. Although we believe that we are in substantial compliance with applicable environmental laws and regulations and that continued compliance with existing requirements will not have a material adverse impact on us, there can be no assurance that this will continue in the future. The EPA, other federal agencies, and various state and local regulatory agencies and jurisdictions routinely promulgate and propose new rules, and issue updated guidance to existing rules. These new rules and rulemakings include, but are not limited to, new air quality standards for ground level ozone, methane, green completions, and hydraulic fracturing and water standards. We are unable to estimate the costs of asset additions or modifications necessary to comply with any new regulations due to uncertainty created by the various legal challenges to these regulations and the need for further specific regulatory guidance.
Matters related to Williams’ former power business
In connection with a Separation and Distribution Agreement between WPX and Williams, Williams is obligated to indemnify and hold us harmless from any losses arising out of liabilities assumed by us for the pending litigation described below relating to the reporting of certain natural gas-related information to trade publications.
Civil suits based on allegations of manipulating published gas price indices have been brought against us and others, seeking unspecified amounts of damages. We are currently a defendant in class action litigation and other litigation originally filed in state court in Colorado, Kansas, Missouri and Wisconsin and brought on behalf of direct and indirect purchasers of natural gas in those states. These cases were transferred to the federal court in Nevada. In 2008, the court granted summary judgment in the Colorado case in favor of us and most of the other defendants based on plaintiffs’ lack of standing. On January 8, 2009, the court denied the plaintiffs’ request for reconsideration of the Colorado dismissal and entered judgment in our favor. On August 6, 2018, the Ninth Circuit reversed the orders denying class certification and remanded to the MDL Court. On September 7, 2018, those plaintiffs filed a motion seeking remand to the originally filed district courts of Missouri, Kansas and Wisconsin. In February 2019, settlement agreements with the Kansas and Missouri class claimants were executed, and on August 5, 2019, after the final fairness hearing, the court approved the settlement and entered final judgment. In the Wisconsin putative class action, the case was remanded to its originally filed court of the Western District of Wisconsin for trial.
In the other cases, on July 18, 2011, the Nevada district court granted our joint motions for summary judgment to preclude the plaintiffs’ state law claims because the federal Natural Gas Act gives the Federal Energy Regulatory Commission exclusive jurisdiction to resolve those issues. The court also denied the plaintiffs’ class certification motion as moot. The plaintiffs appealed to the United States Court of Appeals for the Ninth Circuit. On April 10, 2013, the United States Court of Appeals for the Ninth Circuit issued its opinion in the In re: Western States Wholesale Antitrust Litigation, holding that the Natural Gas Act does not preempt the plaintiffs’ state antitrust claims and reversing the summary judgment previously entered in favor of the defendants. The U.S. Supreme Court granted Defendants’ writ of certiorari. On April 21, 2015, the U.S. Supreme Court determined that the state antitrust claims are not preempted by the federal Natural Gas Act. On March 7, 2016, the putative class plaintiffs in several of the cases filed their motions for class certification. On March 30, 2017, the court denied the motions for class certification, which decision was appealed on June 20, 2017. On May 24, 2016, in Reorganized FLI Inc. v.
Williams Companies, Inc., the Court granted Defendants’ Motion for Summary Judgment in its entirety, and an agreed amended judgment was entered by the court on January 4, 2017. Reorganized FLI, Inc. appealed this decision and on March 27, 2018, the 9th Circuit Court of Appeals reversed and remanded the case to the MDL Court. In May 2019, the MDL Court remanded the case back to Kansas District Court. On December 30, 2019, Defendants petitioned the United States Court of Appeals for the Tenth Circuit to consider their motion for appeal of their motion to reconsider the denial of their motion for summary judgement and the Tenth Circuit granted the petition. Because of the uncertainty around pending unresolved issues, including an insufficient description of the purported classes and other related matters, we cannot reasonably estimate a range of potential exposure at this time.

Other Indemnifications
Pursuant to various purchase and sale agreements relating to divested businesses and assets, including the agreements pursuant to which we divested our Piceance and San Juan Basin operations, we have indemnified certain purchasers against liabilities that they may incur with respect to the businesses and assets acquired from us. The indemnities provided to the purchasers are customary in sale transactions and are contingent upon the purchasers incurring liabilities that are not otherwise recoverable from third parties. The indemnities generally relate to breaches of representations and warranties, tax liabilities, historic litigation, personal injury, environmental matters and rights-of-way. Additionally, Federal and state laws in areas of former operations may require previous operators to perform in certain circumstances where the buyer/operator may no longer be able to perform. Such duties may include plugging and abandoning wells or responsibility for surface agreements in existence at the time of disposition.
The current owner/operator of properties we divested in the Powder River Basin filed for bankruptcy during the fourth quarter of 2019, and it is uncertain to what extent the current owner/operator will perform its obligations with respect to such properties. Prior to our disposition of such properties, payments under the surface use agreements were approximately $6 million annually and our recorded asset retirement obligation under GAAP related to the plugging and abandoning of wells was approximately $46 million.
The indemnity provided to the purchaser of the entity that held our Piceance Basin operations relates in substantial part to liabilities arising in connection with litigation over the appropriate calculation of royalty payments. Plaintiffs in litigation have asserted claims regarding, among other things, the method by which we accounted for transportation costs when calculating royalty payments. In 2017, we settled one of these claims. In February 2019, a royalty-interest owner in Garfield County, filed a putative class action in the District Court of Colorado, Garfield County (State Case), alleging that we breached certain oil and gas leases and overriding royalty agreements by deducting gathering and fuel costs associated with the transportation and processing of gas from royalty and overriding royalty payments since 2011. The royalty-interest owner seeks to represent a class of owners that have interests in leases stating that we can deduct the cost of transporting gas from the well to point of sale. The same royalty-interest owner also filed a putative class action in the United States District Court of Colorado (Federal Case), seeking to represent a class of all royalty owners except tribal and governmental owners, alleging that we breached express and implied duties set forth in oil and gas leases and overriding royalty agreements by underpaying royalties and overriding royalties since July 2011 by failing to “enhance” the value of gas through processing, by deducting unreasonably high transportation costs for residue gas, by failing to prudently market residue gas and NGLs and by failing to pay royalties on the highest obtainable price. At this time, we believe that our royalty calculations have been properly determined in accordance with the appropriate contractual arrangements and applicable laws. We do not have sufficient information to calculate a reasonable estimated range of exposure related to these claims.
In connection with the sale of our San Juan Basin assets in the first quarter of 2018, we left in place and remained subject to a performance guarantee with respect to various gathering and processing commitments. See Note 3 for a discussion of accruals we have recorded in connection with this performance guarantee.
In connection with the separation from Williams, we agreed to indemnify and hold Williams harmless from any losses resulting from the operation of our business or arising out of liabilities assumed by us. Similarly, Williams has agreed to indemnify and hold us harmless from any losses resulting from the operation of its business or arising out of liabilities assumed by it.
As of December 31, 2020, we have not received any additional significant claims against any of these indemnities and thus have no basis from which to estimate any reasonably possible loss beyond any amount already accrued. Further, we do not expect any of the indemnities provided pursuant to the sales agreements to have a material impact on our future financial position. However, if a claim for indemnity is brought against us in the future, it may have a material adverse effect on our results of operations in the period in which the claim is made.
Summary
As of December 31, 2020 and December 31, 2019, the Company had accrued approximately $7 million and $10 million, respectively, for loss contingencies associated with royalty litigation and other contingencies. In certain circumstances, we may be eligible for insurance recoveries, or reimbursement from others. Any such recoveries or reimbursements will be recognized only when realizable.
Management, including internal counsel, currently believes that the ultimate resolution of the foregoing matters, taken as a whole and after consideration of amounts accrued, insurance coverage, recovery from customers or other indemnification arrangements, is not expected to have a materially adverse effect upon our future liquidity or financial position; however, it could be material to our results of operations in any given year.

Commitments
We have minimum commitments with midstream companies for gathering, treating, processing and transportation services associated with moving certain of our production to market. As part of managing our commodity price risk, we may also utilize contracted pipeline capacity to move our oil and natural gas production and third-party purchases of oil and natural gas to other locations in an attempt to obtain more favorable pricing differentials. The midstream service and transportation contract commitments disclosed below include obligations for which liabilities were recorded in 2015 associated with our exit from the Powder River Basin and our abandonment of an area in the Appalachian Basin. As of December 31, 2020, commitments and recorded liabilities associated with our midstream service and transportation contracts are as follows:

 	  	Midstream Services	 	  	Transportation	 	  	Total

Accrued liabilities	  	$	5	 	  	$	2	 	  	$	7	 	
Our transportation commitments will be settled over approximately eleven years.
Total rent expense, excluding amounts capitalized, was $25 million in 2018. Rent charges incurred for drilling rig rentals are capitalized under the successful efforts method of accounting; however, charges for rig release penalties or long term standby charges are expensed as incurred.
Note 12. Leases
Our contracts that are leases or contain leases primarily relate to drilling rigs, compression units and office space. Leases are recorded on the balance sheet when the lease term exceeds one year and we direct the use of an identified asset while receiving substantially all of the economic benefit of the asset. Right-of-use assets are included in other noncurrent assets on the Consolidated Balance Sheet. Lease liabilities are included in accrued and other current liabilities and other noncurrent liabilities on the Consolidated Balance Sheet. We have elected to include both lease and non-lease components for all significant asset classes as a single lease component for measurement purposes. Leases with an initial term of 12 months or less are not recorded on the balance sheet and lease expense for these leases is recognized as incurred. We have elected to include lease costs associated with lease terms of one month or less in our short-term lease disclosure below.
We use judgments and assumptions to determine our discount rate and whether a contract contains a lease. The discount rate used to determine the lease payment liability is based on our estimated incremental borrowing rate.
Certain of our leases include rental payments adjusted periodically for inflation. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. From time to time we may enter into lease contracts that commence in future periods. Lease contracts that will commence subsequent to December 31, 2020 are not significant.

Notes to Consolidated Financial Statements-(Continued)
 
if they are age 40 or older and 6 percent of eligible pay if they are under age 40. Total contributions to this plan were $11 million, $10 million and $10 million for 2020, 2019 and 2018, respectively. Approximately $8 million and $7 million was included in accrued and other current liabilities at December 31, 2020, and 2019, respectively, related to the non-matching annual employer contribution.
Note 14. Stock-Based Compensation
Prior to the closing of the Devon Merger, we had an equity incentive plan (“2013 Incentive Plan”) and an employee stock purchase plan (“ESPP”). The 2013 Incentive Plan authorizes the grant of nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units and other stock-based awards (restricted stock awards, restricted stock units, performance shares and performance units are collectively referred to as restricted stock units and awards for purposes of this footnote).
Total stock-based compensation expense was $38 million, $34 million and $32 million for of the years ended December 31, 2020, 2019 and 2018, respectively, and is reflected in general and administrative expense. Measured but unrecognized stock-based compensation expense related to restricted stock units and awards at December 31, 2020 was $43 million. There was no unrecognized stock-based compensation expense related to stock options at December 31, 2020.
The ESPP allowed employees the option to purchase WPX common stock at a 15 percent discount through after-tax payroll deductions. The purchase price of the stock was the lower of either the first or last day of the biannual offering periods, followed with the 15 percent discount. Employees purchased 141 thousand shares at an average price of $5.29 per share during 2020. The ESPP was terminated in conjunction with the closing of the Devon Merger.

Note 15. Stockholders’ Equity
Preferred Stock
Our amended and restated certificate of incorporation authorizes our Board of Directors to establish one or more series of preferred stock. Unless required by law or by any stock exchange on which our common stock is listed, the authorized shares of preferred stock will be available for issuance without further action. Rights and privileges associated with shares of preferred stock are subject to authorization by our Board of Directors and may differ from those of any and all other series at any time outstanding. As of December 31, 2020, we have no preferred shares outstanding.
Common Stock
Each share of our common stock entitles its holder to one vote in the election of each director. No share of our common stock affords any cumulative voting rights. Holders of our common stock will be entitled to dividends in such amounts and at such times as our Board of Directors in its discretion may declare out of funds legally available for the payment of dividends. No dividends on our common stock were declared or paid for 2020, 2019 or 2018. No shares of common stock are subject to redemption or have preemptive rights to purchase additional shares of our common stock or other securities. As of January 7, 2021, Devon holds all of our common stock.
Subject to certain exceptions, so long as any share of our preferred stock is outstanding, no dividend or distribution shall be declared or paid on the shares of the Company’s common stock or any other class or series of junior stock, and no common stock or any other class or series of junior or parity stock shall be purchased, redeemed or otherwise acquired for consideration by the Company or any of its subsidiaries unless all accumulated and unpaid dividends for all preceding dividend periods have been declared and paid upon, or a sufficient sum of cash or number of shares of the Company’s common stock has been set apart for the payment of such dividends upon, all outstanding shares of preferred stock.
Stock Repurchase Program
On August 5, 2019, we announced that our Board of Directors authorized a plan to repurchase up to $400 million of our outstanding shares over a 24-month period. As of December 31, 2020, we have repurchased approximately 16.1 million shares under the program at an average price of $6.30 per share including 10.4 million shares during first-quarter 2020 at an average price of $4.18 per share. This repurchase program is no longer in place as a result of the Devon Merger.
Felix Acquisition
Part of the consideration for our acquisition of Felix that closed on March 6, 2020, included approximately 153 million shares of our common stock. In addition, we added two new board members to our Board of Directors. See Note 2 for additional discussion of the Felix Acquisition.

Transaction Costs Related to Partnerships
In September and October 2019, we entered into strategic relationships with two third-parties through two newly-formed subsidiaries for purposes of acquiring mineral interests and funding participation in future non-operated well interests. In accordance with and subject to the terms of the agreements, both parties have committed to fund future contributions, subject to certain limits, through the end of 2020 and 2022, respectively. The third-party contributions would represent 80 percent to 85 percent of the total contributions to the partnerships. During 2019, we incurred approximately $6 million of partnership equity commitment and issuance costs, which are recognized as a reduction of additional paid-in-capital within stockholders’ equity attributable to WPX. The Company will be entitled to receive varying percentages of returns based upon achievement of certain predetermined thresholds.
WPX holds a controlling financial interest in these partnerships. Accordingly, we consolidate the financial results of these entities and present the portion attributable to the third parties either as preferred units of consolidated partnership or within other noncurrent liabilities in our consolidated financial statements.
Note 16. Fair Value Measurements
Recurring
Fair value is the amount received from the sale of an asset or the amount paid to transfer a liability in an orderly transaction between market participants (an exit price) at the measurement date. Fair value is a market-based measurement considered from the perspective of a market participant. We use market data or assumptions that we believe market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation. These inputs can be readily observable, market corroborated or unobservable. We apply both market and income approaches for recurring fair value measurements using the best available information while utilizing valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs.
The fair value hierarchy prioritizes the inputs used to measure fair value, giving the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). We classify fair value balances based on the observability of those inputs. The three levels of the fair value hierarchy are as follows:
 
 	•	 	Level 1—Quoted prices for identical assets or liabilities in active markets that we have the ability to access. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Our Level 1 measurements primarily consist of financial instruments that are exchange traded.	
 
 	•	 	Level 2—Inputs are other than quoted prices in active markets included in Level 1 that are either directly or indirectly observable. These inputs are either directly observable in the marketplace or indirectly observable through corroboration with market data for substantially the full contractual term of the asset or liability being measured. Our Level 2 measurements primarily consist of over-the-counter (“OTC”) instruments such as forwards, swaps and options. These options, which hedge future sales of production, are structured as costless collars, calls or swaptions and are financially settled. They are valued using an industry standard Black-Scholes option pricing model. Also categorized as Level 2 is the fair value of our debt, which is determined on market rates and the prices of similar securities with similar terms and credit ratings.	
 
 	•	 	Level 3—Inputs that are not observable for which there is little, if any, market activity for the asset or liability being measured. These inputs reflect management’s best estimate of the assumptions market participants would use in determining fair value. Our Level 3 measurements consist of instruments valued using industry standard pricing models and other valuation methods that utilize unobservable pricing inputs that are significant to the overall fair value.	
In valuing certain contracts, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. For disclosure purposes, assets and liabilities are classified in their entirety in the fair value hierarchy level based on the lowest level of input that is significant to the overall fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the placement within the fair value hierarchy levels.
The following table presents, by level within the fair value hierarchy, our assets and liabilities that are measured at fair value on a recurring basis. The carrying amounts reported in the Consolidated Balance Sheets for cash and cash equivalents and restricted cash approximate fair value due to the nature of the instrument and/or the short-term maturity of these instruments.

(a)	The carrying value of total debt, excluding debt issuance costs, was $3,257 million and $2,229 million as of December 31, 2020 and 2019, respectively.	
Energy derivatives include commodity-based exchange-traded contracts and over-the-counter (“OTC”) contracts.
Exchange-traded contracts include futures, swaps and options. OTC contracts include forwards, swaps, options or swaptions. These are carried at fair value on the Consolidated Balance Sheets.
Many contracts have bid and ask prices that can be observed in the market. Our policy is to use a mid-market pricing (the mid-point price between bid and ask prices) convention to value individual positions and then adjust on a portfolio level to a point within the bid and ask range that represents our best estimate of fair value. For offsetting positions by location, the mid- market price is used to measure both the long and short positions.
The determination of fair value for our derivative assets and liabilities also incorporates the time value of money and various credit risk factors which can include the credit standing of the counterparties involved, master netting arrangements, the impact of credit enhancements (such as cash collateral posted and letters of credit) and our nonperformance risk on our liabilities. The determination of the fair value of our liabilities does not consider noncash collateral credit enhancements.
Forward, swap, option and swaption contracts are considered Level 2 and are valued using an income approach including present value techniques and option pricing models. Option contracts, which hedge future sales of our production, are structured as calls, costless collars, or swaptions and are financially settled. All of our financial options are valued using an industry standard Black-Scholes option pricing model. In connection with swaps, we may sell call options or swaptions to the swap counterparties in exchange for receiving premium hedged prices on the swaps. The sold calls or swaptions establish a maximum price we will receive for the volumes under contract and are financially settled. Significant inputs into our Level 2 valuations include commodity prices, implied volatility and interest rates, as well as considering executed transactions or broker quotes corroborated by other market data. These broker quotes are based on observable market prices at which transactions could currently be executed. In certain instances where these inputs are not observable for all periods, relationships of observable market data and historical observations are used as a means to estimate fair value. Also categorized as Level 2 is the fair value of our debt, which is determined on market rates and the prices of similar securities with similar terms and credit ratings. Where observable inputs are available for substantially the full term of the asset or liability, the instrument is categorized in Level 2.
Our energy derivatives portfolio is largely comprised of over-the-counter products or like products and the tenure of our derivatives portfolio extends through the end of 2024. Due to the nature of the products and tenure, we are consistently able to obtain market pricing. All pricing is reviewed on a daily basis and is formally validated with broker quotes or market indications and documented on a monthly basis.
Certain instruments trade with lower availability of pricing information. These instruments are valued with a present value technique using inputs that may not be readily observable or corroborated by other market data. These instruments are classified within Level 3 when these inputs have a significant impact on the measurement of fair value. We had no instruments included in Level 3 as of December 31, 2020 and 2019, respectively.
Reclassifications of fair value between Level 1, Level 2, and Level 3 of the fair value hierarchy, if applicable, are made at the end of each quarter. No significant transfers between Level 1, Level 2 and Level 3 occurred during the years ended December 31, 2020 or 2019.
Realized and unrealized gains (losses) included in income (loss) from continuing operations for the above periods are reported in revenues on our Consolidated Statements of Operations.
Nonrecurring
As previously noted, we evaluate our long-lived assets for impairment when events or changes in circumstances indicate, in our management’s judgment, that the carrying value of such assets may not be recoverable. The events towards the end of the first quarter, including the significant declines in crude oil prices for 2020, were potential indicators of impairment. Therefore, we performed an assessment of our proved properties at the end of the first quarter.

WPX Energy, Inc.
Notes to Consolidated Financial Statements-(Continued)
 
Our assessment utilized several estimates of future cash flows including scenarios at forecasted prices and at forward market prices. Significant judgments and assumptions in these assessments include estimates of proved, probable and possible reserve quantities, estimates of future commodity prices (developed in consideration of market information, internal forecasts and published forward prices adjusted for locational basis differentials), drilling plans, expected capital costs and an applicable discount rate commensurate with the risk of the underlying cash flow estimates.
Our assessment identified the Williston properties with a carrying value in excess of estimated undiscounted cash flows and as a result, we recorded impairment charges to reduce the net book value of the Williston proved and unproved properties to a probability-weighted estimated fair value totaling approximately $1.0 billion measured on a nonrecurring basis within Level 3 of the fair value hierarchy. This included proved reserves quantities of more than 147 million barrels of oil equivalent, forecasted weighted-average prices averaging approximately $50.84 per Bbl for crude (adjusted for locational differences), forward market weighted-average prices averaging approximately $38.72 per Bbl and after-tax discount rates ranging from 10 percent to 15 percent commensurate with the proved developed, proved undeveloped and probable reserves.
In conjunction with exchanges of leasehold, which may include both proved and unproved leasehold, we estimate the fair value of the leasehold through discounted cash flow models and consideration of market data. Our estimates and assumptions include future commodity prices, projection of estimated quantities of oil and natural gas reserves, expectations for future development and operating costs and risk adjusted discount rates, all of which are Level 3 inputs. For the twelve months ended December 31, 2020, we have recognized gains of approximately $27 million which are included in other (income) expense— net on the Consolidated Statement of Operations.
Note 17. Derivatives and Concentration of Credit Risk Energy Commodity Derivatives
Risk Management Activities
We are exposed to market risk from changes in energy commodity prices within our operations. We utilize derivatives to manage exposure to the variability in expected future cash flows from forecasted sales of crude oil, natural gas and natural gas liquids attributable to commodity price risk.
We produce, buy and sell crude oil, natural gas and natural gas liquids at different locations throughout the United States. To reduce exposure to a decrease in revenues from fluctuations in commodity market prices, we enter into futures contracts, swap agreements, and financial option contracts to mitigate the price risk on forecasted sales of crude oil, natural gas and natural gas liquids. We have also entered into basis swap agreements to reduce the locational price risk associated with our producing basins. Our financial option contracts are either purchased or sold options, or a combination of options that comprise a net purchased option, zero-cost collar or swaptions.

Fair values and gains (losses)
Our derivatives are presented as separate line items in our Consolidated Balance Sheets as current and noncurrent derivative assets and liabilities. Derivatives are classified as current or noncurrent based on the contractual timing of expected future net cash flows of individual contracts. The expected future net cash flows for derivatives classified as current are expected to occur within the next 12 months. The fair value amounts are presented on a gross basis and do not reflect the netting of asset and liability positions permitted under the terms of our master netting arrangements. Further, our derivatives do not include cash held on deposit in margin accounts that we have received or remitted to collateralize certain derivative positions.

Derivative liabilities with right of offset or master netting agreements	  	$	(91	) 	 	$	45	 	 	$	(46	) 	

(a)	With all of our financial trading counterparties, we have agreements in place that allow for the financial right of offset for derivative assets and derivative liabilities at settlement or in the event of a default under the agreements. Additionally, we have negotiated master netting agreements with some of our counterparties. These master netting agreements allow multiple entities that have multiple underlying agreements the ability to net derivative assets and derivative liabilities at settlement or in the event of a default or a termination under one or more of the underlying contracts.	
Credit-risk-related features
Certain of our derivative contracts contain credit-risk-related provisions that would require us, under certain events, to post additional collateral in support of our net derivative liability positions. These credit-risk-related provisions require us to post collateral in the form of cash or letters of credit when our net liability positions exceed an established credit threshold. The credit thresholds are typically based on our senior unsecured debt ratings from Standard and Poor’s and/or Moody’s Investment Services. Under these contracts, a credit ratings decline would lower our credit thresholds, thus requiring us to post additional collateral. We also have contracts that contain adequate assurance provisions giving the counterparty the right to request collateral in an amount that corresponds to the outstanding net liability.
As of December 31, 2020, we did not have any collateral posted to derivative counterparties to support the aggregate fair value of our net $269 million derivative liability position (reflecting master netting arrangements in place with certain counterparties) which includes a reduction of $15 million to our liability balance for our own nonperformance risk. As of December 31, 2019, we did not have any collateral posted to derivative counterparties to support the aggregate fair value of our net $46 million derivative liability position (reflecting master netting arrangements in place with certain counterparties) which includes a reduction of $1 million to our liability balance for our own nonperformance risk. The additional collateral that we would have been required to post, assuming our credit thresholds were eliminated and a call for adequate assurance under the credit risk provisions in our derivative contracts was triggered, was $269 million and $46 million at December 31, 2020 and 2019, respectively.

Oil and natural gas customers include pipelines, distribution companies, producers, marketers and industrial users primarily located in the southwestern United States and North Dakota. As a general policy, collateral is not required for receivables, but customers’ financial condition and credit worthiness are evaluated regularly.
Derivative assets and liabilities
We have a risk of loss from counterparties not performing pursuant to the terms of their contractual obligations.
Counterparty performance can be influenced by changes in the economy and regulatory issues, among other factors. Risk of loss is impacted by several factors, including credit considerations and the regulatory environment in which a counterparty transacts. We attempt to minimize credit-risk exposure to derivative counterparties and brokers through formal credit policies, consideration of credit ratings from public ratings agencies, monitoring procedures, master netting agreements and collateral support under certain circumstances. Collateral support could include letters of credit, payment under margin agreements and guarantees of payment by creditworthy parties.
We also enter into master netting agreements to mitigate counterparty performance and credit risk. During 2020, 2019 and 2018, we did not incur any significant losses due to counterparty bankruptcy filings. We assess our credit exposure on a net basis to reflect master netting agreements in place with certain counterparties. We offset our credit exposure to each counterparty with amounts we owe the counterparty under derivative contracts.
Our gross and net credit exposure from our derivative contracts were $6 million and less than $1 million, respectively, as of December 31, 2020. All of our credit exposure is with investment grade financial institutions. We determine investment grade primarily using publicly available credit ratings. We consider counterparties with a minimum S&P’s rating of BBB- or Moody’s Investors Service rating of Baa3 to be investment grade.
We have one net counterparty position which represents approximately 100 percent of our net credit exposure. Under our marginless hedging agreements with key banks, neither party is required to provide collateral support related to hedging activities.
Other
At December 31, 2020, we held collateral support of $40 million, either in the form of cash, letters of credit or surety bond, related to our commodity management agreements.
Collateral support for our commodity agreements could include margin deposits, letters of credit, and guarantees of payment by credit worthy parties.

Proved Reserves
The SEC defines proved oil and gas reserves (Rule 4-10(a) of Regulation S-X) as those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time. Proved reserves consist of two categories, proved developed reserves and proved undeveloped reserves. Proved developed reserves are currently producing wells and wells awaiting minor sales connection expenditure, recompletion, additional perforations or borehole stimulation treatments. Proved undeveloped reserves are those reserves which are expected to be recovered from new wells on undrilled acreage or from existing wells where a relatively major expenditure is required for recompletion. Proved reserves on undrilled acreage are limited to those that can be developed within five years according to planned drilling activity. Proved reserves on undrilled acreage also can include locations that are more than one offset away from current producing wells where there is a reasonable certainty of production when drilled or where it can be demonstrated with reasonable certainty that there is continuity of production from the existing productive formation.

Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Gas Reserves
The following is based on the estimated quantities of proved reserves. Prices were calculated from the 12-month trailing average, first-of-the-month price for the applicable indices for each basin as adjusted for respective location price differentials. The average domestic oil price used in the estimates for the years ended December 31, 2020, 2019 and 2018 was $36.87, $53.62 and $61.57 per barrel, respectively. The average natural gas price used in the estimates for the years ended December 31, 2020, 2019 and 2018 was $0.95, $0.97 and $1.21 per Mcf, respectively. The average NGL price per barrel was $10.38, $13.23 and $26.76 for the same periods. Future income tax expenses have been computed considering applicable taxable cash flows, including historical tax basis and carry forwards (i.e. future deductions for taxable income calculations), and appropriate statutory tax rates. The discount rate of 10 is as prescribed by authoritative guidance. Continuation of year-end economic conditions also is assumed. The calculation is based on estimates of proved reserves, which are revised over time as new data becomes available. Probable or possible reserves, which may become proved in the future, are not considered. The calculation also requires assumptions as to the timing of future production of proved reserves, and the timing and amount of future development and production costs.
Numerous uncertainties are inherent in estimating volumes and the value of proved reserves and in projecting future production rates and timing of development expenditures. Such reserve estimates are subject to change as additional information becomes available. The reserves actually recovered and the timing of production may be substantially different from the reserve estimates.

Exhibit 99.2
DEVON ENERGY CORPORATION
Unaudited Pro Forma Combined Financial Information
Introduction
On September 26, 2020, Devon, East Merger Sub, Inc., a Delaware corporation and wholly-owned, direct subsidiary of Devon (“Merger Sub”), and WPX Energy, Inc., a Delaware corporation (“WPX”), entered into an Agreement and Plan of Merger (“Merger Agreement”), providing for the merger of Merger Sub with and into WPX, with WPX surviving the merger (the “Merger”) as a wholly-owned, direct subsidiary of Devon. On January 7, 2021, Merger Sub completed the Merger with WPX pursuant to the Merger Agreement. Under the terms and conditions contained in the Merger Agreement, and upon the completion of the Merger, holders of shares of WPX common stock, at their election, received 0.5165 shares of Devon common stock.
The following unaudited pro forma combined financial statements (the “Pro Forma Financial Statements”) have been prepared from the respective historical consolidated financial statements of Devon and WPX and have been adjusted to reflect the completion of the Merger. The unaudited pro forma combined balance sheet data gives effect to the proposed Merger as if it had occurred on December 31, 2020, while the unaudited pro forma combined statement of operations data for the year ended December 31, 2020 is presented as if the Merger had occurred on January 1, 2020. These summary unaudited pro forma combined financial statements have been prepared for illustrative purposes only and are not necessarily indicative of what the combined company’s financial position or results of operations actually would have been had the Merger occurred as of the date indicated. In addition, the unaudited pro forma combined financial statements do not purport to project the future financial position or operating results of the combined company. Future results may vary significantly from the results reflected because of various factors.
The Pro Forma Financial Statements have been developed from and should be read in conjunction with:
 
 	•	 	The audited consolidated financial statements of Devon included in its Annual Report on Form 10-K for the year ended December 31, 2020; and	
 
 	•	 	The audited consolidated financial statements of WPX which are filed as Exhibit 99.1 to this Current Report on Form 8-K/A.	
The Pro Forma Financial Statements have been prepared to reflect adjustments to Devon’s historical consolidated financial information that are (i) directly attributable to the Merger, (ii) factually supportable and (iii) with respect to the Pro Forma Statements of Operations, expected to have a continuing impact on Devon’s results. Accordingly, the Pro Forma Financial Statements reflect the following:
 
 	•	 	the Merger, using the acquisition method of accounting, with Devon as the accounting acquirer and each share of WPX Common Stock converted into 0.5165 of a share of Devon Common Stock;	
 
 	•	 	the assumption of liabilities for expenses directly attributable to the Merger; and	
 
 	•	 	the reclassification of certain of WPX’s historical amounts to conform to Devon’s financial statement presentation.	
The acquisition method of accounting requires fair values be estimated and determined for the merger consideration, as well as the assets acquired and liabilities assumed by Devon upon completing the Merger. As of the date of this report, Devon has not completed the detailed valuation study necessary to arrive at the required final estimates of the fair value of the acquired WPX assets and assumed liabilities and the related purchase price. As soon as practical, Devon will identify the WPX assets acquired and liabilities assumed and make final determinations of their fair values using relevant information available at that time. As a result of the foregoing, the pro forma adjustments with respect to the Merger are preliminary and are subject to change as additional information becomes available and as additional analysis is performed. Any increases or decreases in the merger consideration and the fair value of assets acquired and liabilities assumed upon completion of the final valuations may be materially different from the information presented in the Pro Forma Financial Statements.
Although helpful in illustrating the financial characteristics of the combined company under one set of assumptions, the Pro Forma Financial Statements do not reflect the benefits of expected cost savings (or associated costs to achieve such savings), opportunities to earn additional revenue or other factors that may result after the Merger and, accordingly, do not attempt to predict or suggest future results. Specifically, the Pro Forma Statements of Operations exclude projected synergies expected to be achieved as a result of the Merger, as well as any associated costs that may be required to achieve the identified synergies. The Pro Forma Statements of Operations also exclude the effects of transaction costs associated with the Merger, costs associated with restructuring actions, integration activities or asset dispositions resulting from the Merger, which to the extent they occur, are expected to be non-recurring and will not have been incurred at the closing date of the Merger. However, such costs could affect the combined company following the Merger in the period the costs are incurred or recorded. Further, the Pro Forma Financial Statements do not reflect the effect of any regulatory actions that may impact the results of the combined company following the Merger.

NOTES TO THE UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS:
1. Basis of Presentation
The unaudited pro forma combined financial information has been derived from Devon’s Annual Report on Form 10-K for the year ended December 31, 2020 and the audited financial statements of WPX which are filed as Exhibit 99.1 to this current report on Form 8-K/A. Certain of WPX’s historical amounts have been reclassified to conform to Devon’s financial statement presentation. These Pro Forma Financial Statements should be read in conjunction with the historical financial statements and related notes thereto of Devon and WPX, as well as the pro forma financial information included in the WPX Current Report referenced above.
The Pro Forma Balance Sheet is presented as if the Merger had been completed on December 31, 2020. The Pro Forma Statements of Operations are presented as if the Merger had been completed on January 1, 2020.
The Pro Forma Financial Statements reflect pro forma adjustments that are described in the accompanying notes and are based on currently available information. All adjustments have been made that are necessary to present fairly the Pro Forma Financial Statements. The Pro Forma Financial Statements do not purport to represent what the combined company’s financial position or results of operations would have been if the Merger had actually occurred on the date indicated, nor are they indicative of Devon’s future financial position or results of operations. Actual results may differ materially from the assumptions and estimates reflected in these Pro Forma Financial Statements.
2. Merger Consideration and Purchase Price Allocation
As the accounting acquirer, Devon accounted for the Merger using the acquisition method of accounting for business combinations. The allocation of the preliminary estimated purchase price with respect to the Merger is based upon Devon’s estimates of, and assumptions related to, the fair value of assets acquired and liabilities assumed as of December 31, 2020. Because the unaudited pro forma combined financial statements have been prepared based on these preliminary estimates, the final purchase price allocation and the resulting effect on financial position and results of operations of the combined companies may be materially different from the pro forma amounts included herein. As of the date of this report, Devon has not yet completed the preliminary detailed valuation of the fair value of the acquired WPX assets and assumed liabilities and the related allocations of the purchase price, but will complete as soon as practicable.
The preliminary purchase price allocation is subject to change due to several factors, including but not limited to:
 
 	•	 	changes in the estimated fair value of WPX’s identifiable assets acquired and liabilities assumed as of the closing of the Merger, which could result from changes in oil and natural gas commodity prices, reserve estimates, discount rates and other factors as of the closing date of the Merger;	
 
 	•	 	the tax bases of WPX’s assets and liabilities as of the closing date of the Merger; and	
 
 	•	 	the factors described in the section entitled “Risk Factors” in Item 1A of Devon’s Annual Report on Form 10-K for the period ended December 31, 2020.	

The value of the Merger consideration and its allocation to the net assets acquired is as follows:

3. Pro Forma Adjustments
The following adjustments have been made to the accompanying Pro Forma Financial Statements to give effect to the Merger:
 
 	(a)	The following reclassifications conform WPX’s historical financial information to Devon’s financial statement presentation:	
Pro Forma Balance Sheet as of December 31, 2020
 
 	•	 	Cash, cash equivalents and restricted cash: Reclassification of $23 million of restricted cash in other current assets to cash, cash equivalents and restricted cash.	
 
 	•	 	Current assets: Reclassification of $4 million of derivative assets and $24 million of inventories to other current assets.	
 
 	•	 	Property and equipment: Reclassification of $10.9 billion of properties and equipment to oil and gas property and equipment, net, for $10.1 billion and other property and equipment, net, for $735 million. Reclassification of $2.4 billion of accumulated depreciation, depletion and amortization to oil and gas property and equipment, net, for $2.2 billion and other property and equipment, net, for $162 million. Reclassification of $7 million of pipeline linefill included within other long-term assets to other property and equipment, net.	
 
 	•	 	Other long-term assets: Reclassification of $59 million of other long-term assets to right-of-use assets. Reclassification of $33 million of investments and $2 million of derivative assets to other long-term assets. Reclassification of $7 million of pipeline linefill included within other long-term assets to other property and equipment, net.	

 	•	 	Current liabilities: Reclassification of $255 million of accounts payable to revenues and royalties payable. Reclassification of $43 million of production and severance taxes payable included within other current liabilities to revenues and royalties payable. Reclassification of $242 million of derivative liabilities to other current liabilities.	
 
 	•	 	Other long-term liabilities: Reclassification of $17 million of other long-term liabilities to lease liabilities and $117 million of other-long-term liabilities to asset retirement obligations. Reclassification of $33 million of derivative liabilities to other long-term liabilities.	
Pro Forma Statement of Operations for Year Ended December 31, 2020
 
 	•	 	Revenues: Reclassification of $1.7 billion, $64 million and $145 million of WPX’s disaggregated oil, natural gas and NGL sales, respectively, to aggregated oil, gas and NGL sales. Reclassification of $321 million net gain (loss) on derivatives to oil, gas and NGL derivatives. Reclassification of $199 million of commodity management revenues and $10 million of other revenues to marketing and midstream revenues.	
 
 	•	 	Expenses: Reclassification of $387 million of lease and facility operating expenses, $276 million of gathering, processing and transportation expenses and $131 million of taxes other than income to production expenses. Reclassification of $213 million from commodity management expenses to marketing and midstream expenses. Reclassification of $8 million lower of cost or market adjustment included within commodity management expenses to asset impairments. Reclassification of $28 million of other income to asset dispositions. Reclassification of $193 million of interest expense, $23 million of loss on extinguishment of debt and $2 million of interest income included within other income to financing costs, net. Reclassification of $5 million of asset retirement obligation accretion included within lease and facility operating expense, $13 million of equity earnings, $3 million of other income and $2 million gain on equity method transactions to other expenses.	
 
 	(b)	These adjustments reflect the estimated fair value of Devon Common Stock of $5.4 billion allocated to the estimated fair values of the assets acquired and liabilities assumed as follows:	
 
 	•	 	Total property and equipment, net: $0.3 billion decrease in WPX’s net book value of proved oil and gas properties and $1.2 billion increase in WPX’s unproved oil and gas properties.	
 
 	•	 	Other long-term assets: $307 million increase in the WPX’s net book value of investments and an $6 million decrease in debt issuance costs associated with WPX’s credit facility.	
 
 	•	 	Long-term debt: $349 million increase in WPX’s book value.	
 
 	•	 	Asset retirement obligations: $31 million decrease in WPX’s book value.	
 
 	•	 	Other long-term liabilities: $42 million decrease in WPX’s book value.	
 
 	•	 	Deferred income taxes: $99 million decrease in deferred tax liabilities upon completing the Merger. The combined company has assessed all available evidence and concluded that a 100% valuation allowance is necessary against all U.S. federal and state net deferred tax assets. The combined company’s ability to utilize net operating losses, as well as other credit carryforwards, to offset taxable income and the associated tax liability, may continue to be hindered pursuant to limitations in Section 382 of the Internal Revenue Code and the need for a valuation allowance may continue in future periods.	
 
 	(c)	These adjustments reflect the increase in Devon Common Stock and additional paid-in capital resulting from the issuance of Devon Common Stock to WPX stockholders to effect the transaction.	
 
 	(d)	These adjustments reflect the elimination of WPX’s historical equity balances.	
 
 	(e)	This adjustment reflects the estimated remaining transaction costs of $50 million related to the Merger, including banking, legal and accounting fees that are not capitalized as part of the transaction. The costs are not reflected in the historical December 31, 2020 consolidated balance sheets of Devon and WPX because they have not yet been incurred or were dependent upon the closing of the Merger, but are reflected in the Pro Forma Balance Sheet as an increase to other current liabilities as they will be expensed by Devon and WPX as incurred. These amounts and their corresponding tax effect have not been reflected in the Pro Forma Statements of Operations due to their nonrecurring nature.	
 
 	(f)	These adjustments reflect the decrease to depreciation, depletion and amortization expense resulting from the change in the basis of property and equipment.	
 
 	(g)	The combined company anticipates no material changes to current income tax as a result of the Merger. Further, since the combined company is in a full valuation allowance, no net deferred tax is recorded as a result of changes to pre-tax income/loss or the combined balance sheet. Since the income tax rate used in these Pro Forma Statements of Operations is an estimate, it will likely vary from the actual effective rates in periods subsequent to the Merger due to a variety of reasons including post-merger activities.	
 
 	(h)	These adjustments reflect Devon Common Stock issued to WPX stockholders.

Exhibit 99.3

January 29, 2021
Manager, Corporate Reserves
WPX Energy, Inc.
One Williams Center, Suite 2600
Tulsa, Oklahoma 74172
Dear Sir or Madam:
In accordance with your request, we have audited the estimates prepared by WPX Energy, Inc. and its subsidiaries WPX Energy Williston, LLC and WPX Energy Permian, LLC (collectively referred to herein as “WPX”), as of December 31, 2020, of the proved reserves and future revenue to the WPX interest in certain oil and gas properties located in the United States. It is our understanding that the proved reserves estimates shown herein constitute over 99 percent of all proved reserves owned by WPX. We have examined the estimates with respect to reserves quantities, reserves categorization, future producing rates, future net revenue, and the present value of such future net revenue, using the definitions set forth in U.S. Securities and Exchange Commission (SEC) Regulation S-X Rule 4-10(a). The estimates of reserves and future revenue have been prepared in accordance with the definitions and regulations of the SEC and, with the exception of the exclusion of future income taxes and, as requested, the exclusion of per-well overhead expenses for the operated properties, conform to the FASB Accounting Standards Codification Topic 932, Extractive Activities—Oil and Gas. We completed our audit on or about the date of this letter. This report has been prepared for WPX’s use in filing with the SEC; in our opinion the assumptions, data, methods, and procedures used in the preparation of this report are appropriate for such purpose.
The following table sets forth WPX’s estimates of the net reserves and future net revenue, as of December 31, 2020, for the audited properties:

 	  	Net Reserves	 	  	Future Net Revenue (M$)	 	
Category	  	Oil
        (MBBL)        	 	  	NGL
    (MBBL)    	 	  	Gas
    (MMCF)    	 	  	        Total        	 	  	Present Worth
at 10%	 	
Proved Developed	  	 	269,348	 	  	 	79,596	 	  	 	755,804	 	  	 	4,531,375	 	  	 	2,479,735	 	
Proved Undeveloped	  	 	124,253	 	  	 	30,971	 	  	 	312,900	 	  	 	2,010,104	 	  	 	735,114	 	
	  	 	 	 	  	 	 	 	  	 	 	 	  	 	 	 	  	 	 	 	
Total Proved	  	 	393,601	 	  	 	110,567	 	  	 	1,068,704	 	  	 	6,541,480	 	  	 	3,214,849	 	
Totals may not add because of rounding.
The oil volumes shown include crude oil and condensate. Oil and natural gas liquids (NGL) volumes are expressed in thousands of barrels (MBBL); a barrel is equivalent to 42 United States gallons. Gas volumes are expressed in millions of cubic feet (MMCF) at standard temperature and pressure bases.
When compared on a well-by-well basis, some of the estimates of WPX are greater and some are less than the estimates of Netherland, Sewell & Associates, Inc. (NSAI). However, in our opinion the estimates shown herein of WPX’s reserves and future revenue are reasonable when aggregated at the proved developed, proved undeveloped, and total proved levels and have been prepared in accordance with the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers (SPE Standards). Additionally, these estimates are within the recommended 10 percent tolerance threshold set forth in the SPE Standards. We are satisfied with the methods and procedures used by WPX in preparing the December 31, 2020, estimates of reserves and future revenue, and we saw nothing of an unusual nature that would cause us to take exception with the estimates, in the aggregate, as prepared by WPX.

Reserves categorization conveys the relative degree of certainty; reserves subcategorization is based on development and production status. The estimates of reserves and future revenue included herein have not been adjusted for risk. WPX’s estimates do not include probable or possible reserves that may exist for these properties, nor do they include any value for undeveloped acreage beyond those tracts for which undeveloped reserves have been estimated.
Prices used by WPX are based on the 12-month unweighted arithmetic average of the first-day-of-the-month price for each month in the period January through December 2020. For oil and NGL volumes, the average West Texas Intermediate posted price of $36.04 per barrel is adjusted for quality, transportation fees, and market differentials. For gas volumes, the average Waha spot price of $1.140 per MMBTU is used for the Permian basin properties and the average Chicago city-gates spot price of $1.867 per MMBTU is used for the Williston properties. These average regional spot prices are adjusted for energy content, transportation fees, and market differentials. All prices are held constant throughout the lives of the properties. The average adjusted product prices weighted by production over the remaining lives of the properties are $36.87 per barrel of oil, $10.38 per barrel of NGL, and $0.95 per MCF of gas. By area, these average adjusted prices are $37.65 per barrel of oil, $11.55 per barrel of NGL, and $1.35 per MCF of gas for the Permian basin properties and $34.34 per barrel of oil, $3.74 per barrel of NGL, and -$3.30 per MCF of gas for the Williston basin properties.
Operating costs used by WPX are based on historical operating expense records. For the nonoperated properties, these costs include the per-well overhead expenses allowed under joint operating agreements along with estimates of costs to be incurred at and below the district and field levels. Operating costs for the operated properties are limited to direct lease- and field-level costs and WPX’s area-level estimates of the portion of its headquarters general and administrative overhead expenses necessary to operate the properties. Operating costs have been divided into field-level costs, per-well costs, and per-unit-of-production costs. Capital costs used by WPX are based on authorizations for expenditure and actual costs from recent activity. Capital costs are included as required for workovers, new development wells, and production equipment. Abandonment costs used are WPX’s estimates of the costs to abandon the wells and production facilities, net of any salvage value. Operating, capital, and abandonment costs are not escalated for inflation. Additionally, although we are aware of firm transportation contracts that are in place for these properties, the associated costs are considered by WPX to be corporate-level expenses; no adjustments have been made to our estimates of future revenue to account for such contracts.
The reserves shown in this report are estimates only and should not be construed as exact quantities. Proved reserves are those quantities of oil and gas which, by analysis of engineering and geoscience data, can be estimated with reasonable certainty to be economically producible; probable and possible reserves are those additional reserves which are sequentially less certain to be recovered than proved reserves. Estimates of reserves may increase or decrease as a result of market conditions, future operations, changes in regulations, or actual reservoir performance. In addition to the primary economic assumptions discussed herein, estimates of WPX and NSAI are based on certain assumptions including, but not limited to, that the properties will be developed consistent with current development plans as provided to us by WPX, that the properties will be operated in a prudent manner, that no governmental regulations or controls will be put in place that would impact the ability of the interest owner to recover the reserves, and that projections of future production will prove consistent with actual performance. If the reserves are recovered, the revenues therefrom and the costs related thereto could be more or less than the estimated amounts. Because of governmental policies and uncertainties of supply and demand, the sales rates, prices received for the reserves, and costs incurred in recovering such reserves may vary from assumptions made while preparing these estimates.
It should be understood that our audit does not constitute a complete reserves study of the audited oil and gas properties. Our audit consisted primarily of substantive testing, wherein we conducted a detailed review of all properties. In the conduct of our audit, we have not independently verified the accuracy and completeness of information and data furnished by WPX with respect to ownership interests, oil and gas production, well test data, historical costs of operation and development, product prices, or any agreements relating to current and future operations of the properties and sales of production. However, if in the course of our examination something came to our attention that brought into question the validity or sufficiency of any such information or data, we did not rely on such information or data until we had satisfactorily resolved our questions relating thereto or had independently verified such information or data. Our audit did not include a review of WPX’s overall reserves management processes and practices.

We used standard engineering and geoscience methods, or a combination of methods, including performance analysis, volumetric analysis, and analogy, that we considered to be appropriate and necessary to establish the conclusions set forth herein. As in all aspects of oil and gas evaluation, there are uncertainties inherent in the interpretation of engineering and geoscience data; therefore, our conclusions necessarily represent only informed professional judgment.
Supporting data documenting this audit, along with data provided by WPX, are on file in our office. The technical persons primarily responsible for conducting this audit meet the requirements regarding qualifications, independence, objectivity, and confidentiality set forth in the SPE Standards.
