NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.	Summary of Significant Accounting Policies

The accompanying unaudited interim financial statements and notes of Devon have been prepared pursuant to the rules and regulations of the SEC. Pursuant to such rules and regulations, certain disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been omitted. The accompanying unaudited interim financial statements and notes should be read in conjunction with the financial statements and notes included in Devon’s 2020 Annual Report on Form 10-K. The accompanying unaudited interim financial statements in this report reflect all adjustments that are, in the opinion of management, necessary for a fair statement of Devon’s results of operations and cash flows for the three-month and nine-month periods ended September 30, 2021 and 2020 and Devon’s financial position as of September 30, 2021.

Devon and WPX completed an all-stock merger of equals on January 7, 2021. On the closing date of the Merger, each share of WPX common stock was automatically converted into the right to receive 0.5165 of a share of Devon common stock. The transaction has been accounted for using the acquisition method of accounting, with Devon being treated as the accounting acquirer. See Note 2 for further discussion.

As further discussed in Note 17, Devon closed on the sale of its Barnett Shale assets in October 2020. Prior to December 31, 2020, activity relating to Devon’s Barnett Shale assets is classified as discontinued operations within Devon’s consolidated statements of comprehensive earnings and consolidated statements of cash flows.

As of September 30, 2021, Devon classified approximately $165 million of cash as restricted cash on the consolidated balance sheets for obligations retained related to the Barnett Shale assets and the Canadian business. Cash payments for these charges related to the Barnett assets and Canada business total approximately $10 million per quarter.

Variable Interest Entity

Cotton Draw Midstream, L.L.C. (“CDM”) is a joint venture entity formed by Devon and an affiliate of QL Capital Partners, LP. CDM provides gathering, compression and dehydration services for natural gas production in the Cotton Draw area of the Delaware Basin. Devon holds a controlling interest in CDM and the portions of CDM’s net earnings and equity not attributable to Devon’s controlling interest are shown separately as noncontrolling interests in the accompanying consolidated statements of comprehensive earnings and consolidated balance sheets. CDM is considered a VIE to Devon. The assets of CDM cannot be used by Devon for general corporate purposes and are included in, and disclosed parenthetically, on Devon's consolidated balance sheets. The carrying amount of liabilities related to CDM for which the creditors do not have recourse to Devon's assets are also included in, and disclosed parenthetically, if material, on Devon's consolidated balance sheets.

Investments

In conjunction with the Merger, Devon acquired an interest in Catalyst which is a joint venture established between WPX and Howard Energy Partners (“HEP”) to develop oil gathering and natural gas processing infrastructure in the Stateline area of the Delaware Basin. Under the terms of the arrangement, Devon and HEP each have a 50 percent voting interest in the joint venture legal entity, and HEP serves as the operator. Through 2038, Devon’s production from 50,000 net acres in the Stateline area of the Delaware Basin has been dedicated to Catalyst subject to fixed-fee oil gathering and natural gas processing agreements. The agreements do not include any minimum volume commitments. Devon accounts for the investment in Catalyst as an equity method investment. Devon’s investment in Catalyst is shown within investments on the consolidated balance sheet and Devon’s share of Catalyst earnings are reflected as a component of other, net in the accompanying consolidated statements of comprehensive earnings.

WPX Merger

On January 7, 2021, Devon and WPX completed an all-stock merger of equals. WPX was an oil and gas exploration and production company with assets in the Delaware Basin in Texas and New Mexico and the Williston Basin in North Dakota. On the closing date of the Merger, each share of WPX common stock was automatically converted into the right to receive 0.5165 of a share of Devon common stock. No fractional shares of Devon’s common stock were issued in the Merger, and holders of WPX common stock instead received cash in lieu of fractional shares of Devon common stock, if any. Based on the closing price of Devon’s common stock on January 7, 2021, the total value of Devon common stock issued to holders of WPX common stock as part of this transaction was approximately $5.4 billion. The Merger was structured as a tax-free reorganization for United States federal income tax purposes.

Purchase Price Allocation

The transaction has been accounted for using the acquisition method of accounting, with Devon being treated as the accounting acquirer. Under the acquisition method of accounting, the assets and liabilities of WPX and its subsidiaries have been recorded at their respective fair values as of the date of completion of the Merger and added to Devon’s. The preliminary purchase price assessment remains an ongoing process and is subject to change for up to one year subsequent to the closing date of the Merger. Determining the fair value of the assets and liabilities of WPX requires judgment and certain assumptions to be made, the most significant of these being related to the valuation of WPX’s oil and gas properties. The inputs and assumptions related to the oil and gas properties are categorized as level 3 in the fair value hierarchy.

The following table represents the preliminary allocation of the total purchase price of WPX to the identifiable assets acquired and the liabilities assumed based on the fair values as of the acquisition date.

Divestitures

In the first quarter of 2021, Devon completed the sale of non-core assets in the Rockies for proceeds of $9 million, net of purchase price adjustments, and recognized a $35 million gain related to the sale. The transaction includes contingent earnout payments of up to $8 million. The total estimated proved reserves associated with these divested assets was approximately 3 MMBoe. As of December 31, 2020, the associated assets and liabilities were classified as assets held for sale and included in other current assets and other current liabilities, respectively.

In the fourth quarter of 2020, Devon completed the sale of its Barnett Shale assets to BKV for proceeds, net of purchase price adjustments, of $490 million. The agreement with BKV also provides for contingent earnout payments to Devon of up to $260 million based upon future commodity prices, with upside participation beginning at a $2.75 Henry Hub natural gas price or a $50 WTI oil price. The contingent payment period commenced on January 1, 2021 and has a term of four years. The valuation of the future contingent earnout payments included within other current assets and other long-term assets in the September 30, 2021 consolidated balance sheet was $46 million and $85 million, respectively. During the first nine months of 2021, Devon recorded a $65 million increase to the fair value within asset dispositions on the consolidated statements of comprehensive earnings. The value was derived utilizing a Monte Carlo valuation model and qualifies as a level 3 fair value measurement. Additional information can be found in Note 17.

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

3.Derivative Financial Instruments

Objectives and Strategies

Devon enters into derivative financial instruments with respect to a portion of its oil, gas and NGL production to hedge future prices received. Additionally, Devon periodically enters into derivative financial instruments with respect to a portion of its oil, gas and NGL marketing activities. These commodity derivative financial instruments include financial price swaps, price swaptions, basis swaps, costless price collars and call options. Devon periodically enters into interest rate swaps to manage its exposure to interest rate volatility. As of September 30, 2021, Devon did not have any open interest rate swap contracts.

Devon does not intend to hold or issue derivative financial instruments for speculative trading purposes and has elected not to designate any of its derivative instruments for hedge accounting treatment.

Counterparty Credit Risk

By using derivative financial instruments, Devon is exposed to credit risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. To mitigate this risk, the hedging instruments are placed with a number of counterparties whom Devon believes are acceptable credit risks. It is Devon’s policy to enter into derivative contracts only with investment-grade rated counterparties deemed by management to be competent and competitive market makers. Additionally, Devon’s derivative contracts generally contain provisions that provide for collateral payments if Devon’s or its counterparty’s credit rating falls below certain credit rating levels. As of September 30, 2021, Devon neither held cash collateral of its counterparties nor posted cash collateral to its counterparties.

Commodity Derivatives

As of September 30, 2021, Devon had the following open oil derivative positions. The first table presents Devon’s oil derivatives that settle against the average of the prompt month NYMEX WTI futures price.

Proved Oil and Gas and Other Asset Impairments

Due to the reduced demand from the COVID-19 pandemic causing an unprecedented downturn in the price of oil and reductions in near-term capital investment, Devon recognized approximately $2.7 billion of proved asset impairments during the first quarter of 2020. These impairments related to the Anadarko Basin and Rockies fields in which the cost basis included acquisitions completed in 2016 and 2015, respectively, when commodity prices were much higher. During the first quarter of 2020, Devon also recognized $2 million of product line fill impairments.

Unproved Impairments

Due to the downturn in the commodity price environment and reduced near-term investment as discussed above, Devon also recognized $149 million of unproved impairments during the first nine months of 2020, primarily in the Rockies field.

Additionally, in conjunction primarily with the Merger closing, Devon recognized $48 million of transaction costs primarily comprised of bank, legal and accounting fees.

In the third quarter of 2020, Devon recognized $32 million of restructuring expenses. Of these expenses, $11 million resulted from the accelerated vesting of share-based grants, which are non-cash charges.

Income Tax Disclosure [Abstract]

Income Taxes

7.Income Taxes

The following table presents Devon’s total income tax expense (benefit) and a reconciliation of its effective income tax rate to the U.S. statutory income tax rate.

	Three Months Ended September 30,					Nine Months Ended September 30,
	2021		2020			2021			2020
Earnings (loss) from continuing operations before income taxes	$	964	$	(193	)	$	1,236		$	(2,980	)

Current income tax expense (benefit)	$	1	$	(90	)	$	15		$	(199	)
Deferred income tax expense (benefit)		119		—			(100	)		(311	)
Total income tax expense (benefit)	$	120	$	(90	)	$	(85	)	$	(510	)

U.S. statutory income tax rate	21	%	21	%	21	%	21	%
State income taxes	0	%	0	%	0	%	1	%
Unrecognized tax benefits	0	%	18	%	0	%	0	%
Deferred tax asset valuation allowance	(9	%)	4	%	(33	%)	(7	%)
Other	0	%	4	%	5	%	2	%
Effective income tax rate	12	%	47	%	(7	%)	17	%

The deferred income tax benefit recognized in the first nine months of 2021 primarily relates to the Merger and a reduced valuation allowance due to increased earnings. As shown in Note 2, Devon recognized $249 million of deferred tax liabilities to account for the Merger. The recognition of these deferred tax liabilities caused a decrease to Devon’s net deferred tax assets and a corresponding decrease to the valuation allowance Devon has recognized on its U.S. Federal deferred tax assets. Additionally, improved commodity prices and post-merger operating performance are causing reductions to Devon’s net operating losses, which also cause corresponding decreases to the associated deferred tax assets and valuation allowance.

As of September 30, 2021, Devon continued to maintain a valuation allowance against certain U.S. deferred tax assets. Devon continues to assess its valuation allowance position every quarter. Subject to any additional objective negative evidence or the addition of subjective evidence such as forecasted income, Devon may continue to adjust the valuation allowance on its deferred tax assets in future periods.

In the fourth quarter of 2020, Devon recorded a deferred tax asset representing the deductible outside basis difference in its investment in a consolidated subsidiary. In the second quarter of 2021, Devon realized this deferred tax asset, increasing its U.S. federal net operating loss carryforwards by $1.8 billion.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

On or after these dates, Devon has or had the option to redeem the notes, in whole or in part, at the applicable redemption prices set forth in the indenture documents, plus accrued and unpaid interest thereon to the redemption date as more fully described in such documents.

Retirement of Senior Notes

In the first nine months of 2021, Devon redeemed $43 million of the 6.00% senior notes due 2022, $175 million of the 5.875% senior notes due 2028, $315 million of the 4.50% senior notes due 2030, $210 million of the 5.25% senior notes due 2027 and $500 million of the 5.75% senior notes due 2026.

The gain on early retirement is included in financing costs, net in the consolidated statements of comprehensive earnings.

Credit Lines

Devon has a $3.0 billion Senior Credit Facility. As of September 30, 2021, Devon had no outstanding borrowings under the Senior Credit Facility and had issued $2 million in outstanding letters of credit under this facility. The Senior Credit Facility contains only one material financial covenant. This covenant requires Devon’s ratio of total funded debt to total capitalization, as defined in the credit agreement, to be no greater than 65%. Under the terms of the credit agreement, total capitalization is adjusted to add back non-cash financial write-downs such as impairments. As of September 30, 2021, Devon was in compliance with this covenant with a debt-to-capitalization ratio of 25.1%.

Net Financing Costs

The following schedule includes the components of net financing costs.

On the closing date of the Merger, each share of WPX common stock was automatically converted into the right to receive 0.5165 of a share of Devon common stock. Consequently, Devon issued approximately 290 million shares of Devon common stock to holders of WPX common stock to effect the Merger on January 7, 2021.

Share Repurchases

Discontinued Operations

17.	Discontinued Operations

On October 1, 2020, Devon completed the sale of its Barnett Shale assets to BKV for proceeds, net of purchase price adjustments, of $490 million. Additionally, the agreement provides for contingent earnout payments to Devon of up to $260 million based upon future commodity prices, with upside participation beginning at a $2.75 Henry Hub natural gas price or a $50 WTI oil price. The contingent payment period commenced on January 1, 2021 and has a term of four years.

The following table presents the amounts reported in the consolidated statements of comprehensive earnings as discontinued operations.

	Three Months Ended September 30, 2020			Nine Months Ended September 30, 2020
Oil, gas and NGL sales	$	94		$	263
Total revenues		94			263
Production expenses		66			214

Net earnings (loss) from discontinued operations, net of tax	$	13		$	(103	)

(1)

Devon recognized $182 million of asset impairments in the first nine months of 2020 related to the Barnett Shale assets primarily due to the difference between the net carrying value and the purchase price, net of estimated customary purchase price adjustments, which qualified as a level 2 fair value measurement.

Commitments And Contingencies Disclosure [Abstract]

Commitments And Contingencies

18.	Commitments and Contingencies

Devon is party to various legal proceedings and other matters that may result in future payment obligations or other adverse consequences to its business. Matters that are probable of an unfavorable outcome to Devon and which any related potential payment obligation or other liability can be reasonably estimated are accrued. Such accruals are based on information known about the matters, Devon’s estimates of the outcomes of such matters and its experience in contesting, litigating and settling similar matters. While management does not believe any current matter is likely to involve future amounts that would be material to Devon’s financial position or results of operations after consideration of recorded accruals, the ultimate outcome of such matters and the amounts involved could differ materially from management’s estimates.

Royalty Matters

Numerous oil and natural gas producers and related parties, including Devon, have been named in various lawsuits alleging royalty underpayments. Devon is currently defending against a number of such lawsuits, either as a named defendant in the action or pursuant to indemnity obligations for the benefit of a third party. Plaintiffs in some of these lawsuits are seeking class certification. Among the allegations typically asserted in these suits are claims that Devon used below-market prices, made improper deductions, failed to “enhance” the value of gas through processing, used improper measurement techniques, entered into purchase and midstream arrangements with affiliates that resulted in underpayment of royalties or otherwise failed to prudently market oil, natural gas and NGLs produced and sold and pay royalties on the highest obtainable price. Devon is also involved in governmental agency proceedings and royalty audits and is subject to related contracts and regulatory controls in the ordinary course of business, some that may lead to additional royalty claims. Devon does not currently believe that it is subject to material exposure with respect to such royalty matters.

Environmental and Climate Change Matters

Devon’s business is subject to numerous federal, state, local and Native American tribal 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, as well as remediation costs. Although Devon believes that it is in substantial compliance with applicable environmental laws and regulations and that continued compliance with existing requirements will not have a material adverse impact on its business, there can be no assurance that this will continue in the future.

Beginning in 2013, various parishes in Louisiana filed suit against numerous oil and gas companies, including Devon, alleging that the companies’ operations and activities in certain fields violated the State and Local Coastal Resource Management Act of 1978, as amended, and caused substantial environmental contamination, subsidence and other environmental damages to land and water bodies located in the coastal zone of Louisiana. The plaintiffs’ claims against Devon relate primarily to the operations of several of Devon’s corporate predecessors. The plaintiffs seek, among other things, the payment of the costs necessary to clear, re-vegetate and otherwise restore the allegedly impacted areas. Although Devon cannot predict the ultimate outcome of these matters, Devon believes these claims to be baseless and is vigorously defending against these claims.

The State of Delaware and various municipalities and other governmental and private parties in California have filed legal proceedings against numerous oil and gas companies, including Devon, seeking relief to abate alleged impacts of climate change. These proceedings include far-reaching claims for monetary damages and injunctive relief. Although Devon cannot predict the ultimate outcome of these matters, Devon believes these claims to be baseless and intends to vigorously defend against the proceedings.

Williams’ Former Power Business Matter

Direct and indirect purchasers of natural gas in various states filed individual and class action lawsuits against The Williams Companies, Inc. (“Williams”) and other parties alleging the manipulation of published gas price indices and seeking unspecified amounts of damages. WPX and certain of its subsidiaries, which were then affiliates of Williams, were also named as defendants in these actions.

Devon cannot reasonably estimate a range of potential exposure at this time for these matters. In connection with its spin-off from Williams in 2011, WPX entered into a separation and distribution agreement with Williams, pursuant to which Williams agreed to indemnify and hold WPX and its subsidiaries harmless from any losses arising out of these matters.

Other Indemnifications and Legacy Matters

Pursuant to various sale agreements relating to divested businesses and assets, Devon has indemnified various purchasers against liabilities that they may incur with respect to the businesses and assets acquired from Devon. Additionally, federal, state and other laws in areas of former operations may require previous operators (including corporate successors of previous operators) to perform or make payments in certain circumstances where the current operator may no longer be able to satisfy the applicable obligation. Such obligations may include plugging and abandoning wells, removing production facilities or performing requirements under surface agreements in existence at the time of disposition.

In November 2020, the Department of the Interior, Bureau of Safety and Environmental Enforcement, ordered several oil and gas operators, including Devon, to perform decommissioning and reclamation activities related to two California offshore oil and gas production platforms and related facilities. The current operator and owner of the platforms contends that it does not have the financial ability to perform these obligations and relinquished the related federal lease in October 2020. In response to the apparent insolvency of the current operator, the government has ordered the former operators and alleged former lease record title owners to decommission the platforms. The government contends that an alleged corporate predecessor of Devon owned a partial interest in the subject lease and platforms. Although Devon cannot predict the ultimate outcome of this matter, Devon denies any obligation to decommission the subject platforms, has appealed the order, and believes any decommissioning obligation related to the subject platforms should be assumed by others.

Fair Value Measurements

19.	Fair Value Measurements

The following table provides carrying value and fair value measurement information for certain of Devon’s financial assets and liabilities. The carrying values of cash, accounts receivable, other current receivables, accounts payable, other current payables, accrued expenses and lease liabilities included in the accompanying consolidated balance sheets approximated fair value at September 30, 2021 and December 31, 2020, as applicable. Therefore, such financial assets and liabilities are not presented in the following table. Additionally, information regarding the fair values of oil and gas assets is provided in Note 5.

							Fair Value Measurements Using:
	Carrying			Total Fair			Level 1		Level 2			Level 3

Contingent earnout payments	$	66		$	66		$	—	$	—		$	66

The following methods and assumptions were used to estimate the fair values in the table above.

Level 1 Fair Value Measurements

Cash equivalents – Amounts consist primarily of money market investments and the fair value approximates the carrying value.

Level 2 Fair Value Measurements

Commodity derivatives – The fair value of commodity derivatives is estimated using internal discounted cash flow calculations based upon forward curves and data obtained from independent third parties for contracts with similar terms or data obtained from counterparties to the agreements.

Debt – Devon’s debt instruments do not consistently trade actively in an established market. The fair values of its debt are estimated based on rates available for debt with similar terms and maturity when active trading is not available.

Level 3 Fair Value Measurements

Contingent Earnout Payments – Devon has the right to receive contingent consideration related to the Barnett and non-core Rockies asset divestitures based on future oil and gas prices. These values were derived using a Monte Carlo valuation model and qualify as a level 3 fair value measurement. For additional information, see Note 2.

Schedule of Revenue from Contracts with Customers
