1.     Summary of Significant Accounting Policies 

The accompanying unaudited consolidated financial statements and notes of Devon Energy Corporation ("Devon") have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission. Pursuant to such rules and regulations, certain disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted. The accompanying consolidated financial statements and notes should be read in conjunction with the consolidated financial statements and notes included in Devon's 2010 Annual Report on Form 10-K.  

The unaudited interim consolidated financial statements furnished in this report reflect all adjustments that are, in the opinion of management, necessary to a fair statement of Devon's financial position as of June 30, 2011 and Devon's results of operations and cash flows for the three-month and six-month periods ended June 30, 2011 and 2010.

Recently Issued Accounting Standards Not Yet Adopted

In May 2011, the FASB issued Accounting Standards Update 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS. This update does not require additional fair value measurements and is not intended to establish valuation standards or affect valuation practices outside of financial reporting. However, beginning in Devon's 2011 Annual Report on Form 10-K, this update will require certain additional disclosures related to Devon's fair value measurements. Devon does not expect the adoption of this update will materially impact its financial statement disclosures.

In June 2011, the FASB issued Accounting Standards Update 2011-05, Presentation of Comprehensive Income. Beginning in Devon's 2011 Annual Report on Form 10-K, this update will give Devon the option to present the total of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. Devon has not determined which presentation option it will choose but does not expect its selection to materially impact the presentation of its financial statements.

2.    Short-Term Investments

Devon periodically invests excess cash in U.S. Treasury and other marketable securities that are presented as short-term investments in the accompanying June 30, 2011 consolidated balance sheet. During the first half of 2011, Devon invested a portion of the International offshore divestiture proceeds it had received into United States Treasury securities, causing short-term investments to increase. The carrying value of these investments approximates their fair value. As of June 30, 2011, the average remaining maturity of these investments was 67 days, with a weighted average yield of 0.06 percent.

3.  Accounts Receivable

The components of accounts receivable include the following:

4.  Derivative Financial Instruments

Objectives and Strategies

Devon periodically enters into commodity and interest rate derivative financial instruments. These instruments are used to manage the inherent uncertainty of future revenues due to oil, gas and NGL price volatility and to manage exposure to interest rate volatility.  Devon does not 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.

Devon's derivative financial instruments include financial price swaps, basis swaps, costless price collars and call options. Under the terms of the price swaps, Devon receives a fixed price for its production and pays a variable market price to the contract counterparty. For the basis swaps, Devon receives a fixed differential between two regional gas index prices and pays a variable differential on the same two index prices to the contract counterparty. The price collars set a floor and ceiling price for the hedged production. If the applicable monthly price indices are outside of the ranges set by the floor and ceiling prices in the various collars, Devon will cash-settle the difference with the counterparty to the collars. Under the terms of the call options, Devon sold to counterparties the right to purchase production at a predetermined price.

Devon periodically enters into interest rate swaps to manage its exposure to interest rate volatility. Devon's interest rate swaps include contracts in which Devon receives a fixed rate and pays a variable rate on a total notional amount. Devon also had forward starting swaps and U.S. Treasury locks. In conjunction with Devon's debt issuance discussed in Note 7, Devon received $35 million from the net settlement of its forward starting swaps and U.S. Treasury locks in July 2011.

Counterparty Risk

By using derivative financial instruments to manage exposures to changes in commodity prices and interest rates, Devon exposes itself to credit risk and market 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 minimal 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 require cash collateral to be posted if either its or the counterparty's credit rating falls below investment grade. The mark-to-market exposure threshold, above which collateral must be posted, decreases as the debt rating falls further below investment grade. Such thresholds generally range from zero to $55 million for the majority of Devon's contracts. As of June 30, 2011, the credit ratings of all Devon's counterparties were investment grade.

Commodity Derivatives

As of June 30, 2011, Devon had the following open oil derivative positions. Devon's oil derivatives settle against the average of the prompt month NYMEX West Texas Intermediate futures price.

As of June 30, 2011, Devon had the following open natural gas derivative positions. Devon's natural gas derivative swaps, collars and call options settle against the Inside Ferc first of the month Henry Hub index.

As of June 30, 2011, Devon had the following open NGL derivative positions:

5.     Other Current Assets

  The components of other current assets include the following:

6.    Goodwill

During the first six months of 2011, Devon's Canadian goodwill increased $96 million entirely due to foreign currency translation.

7.     Debt

Credit Lines

Devon has a $2.7 billion syndicated, unsecured revolving line of credit (the "Senior Credit Facility"). As of June 30, 2011, Devon had no borrowings under the Senior Credit Facility.

The Senior Credit Facility contains only one material financial covenant. This covenant requires Devon's ratio of total funded debt to total capitalization to be less than 65 percent. The credit agreement contains definitions of total funded debt and total capitalization that include adjustments to the respective amounts reported in the consolidated financial statements. Also, total capitalization is adjusted to add back noncash financial writedowns such as full cost ceiling impairments or goodwill impairments. As of June 30, 2011, Devon was in compliance with this covenant. Devon's debt-to-capitalization ratio at June 30, 2011, as calculated pursuant to the terms of the agreement, was 19.3 percent.

Commercial Paper

In March 2011, Devon's Board of Directors authorized an increase in its commercial paper program from $2.2 billion to $5.0 billion. Commercial paper debt generally has a maturity of between 1 and 90 days, although it can have a maturity of up to 365 days, and bears interest at rates agreed to at the time of the borrowing. The interest rate is based on a standard index such as the Federal Funds Rate, LIBOR, or the money market rate as found on the commercial paper market.

Although Devon ended the second quarter of 2011 with approximately $6.7 billion of cash and short-term investments, the vast majority of this amount consists of proceeds from its International divestitures. Based on Devon's evaluation of future cash needs across its operations in the United States and Canada, these proceeds remain outside of the United States.

Consequently, during the first six months of 2011, Devon borrowed $2.3 billion of commercial paper in the United States primarily to fund capital expenditures, common stock repurchases and dividends in excess of cash flow generated by its United States operating activities. As of June 30, 2011, Devon's average borrowing rate on its $2.3 billion of commercial paper borrowings was 0.27 percent.

In July 2011, Devon received net proceeds totaling $2,224 million from the issuance of $500 million of 2.40% senior notes due July 15, 2016, $500 million of 4.00% senior notes due July 15, 2021 and $1,250 million of 5.60% senior notes due July 15, 2041. The net proceeds from issuance of this long-term debt is being used to repay substantially all of Devon's outstanding commercial paper as of June 30, 2011 as it matures. Therefore, $2,224 million of Devon's outstanding commercial paper is classified as long-term debt in the accompanying June 30, 2011 consolidated balance sheet.

8.     Asset Retirement Obligations

The schedule below summarizes changes in Devon's asset retirement obligations.

During the first six months of 2010, Devon recognized a revision to its asset retirement obligations totaling $194 million. The increase was primarily due to an overall increase in abandonment cost estimates and a decrease in the discount rate used to calculate the present value of the obligations.

During the first six months of 2010, Devon reduced its asset retirement obligations by $256 million for those obligations that were assumed by purchasers of Devon's Gulf of Mexico oil and gas properties in 2010.

10.  Stockholders' Equity

Stock Repurchases

During the first six months of 2011, Devon repurchased 15.2 million common shares under its $3.5 billion stock repurchase program announced in 2010 for $1.3 billion, or $84.52 per share. As of June 30, 2011, Devon had repurchased 33.5 million common shares for $2.5 billion, or $74.16 per share, under this program, which expires December 31, 2011.

Dividends

Devon paid common stock dividends of $140 million and $142 million in the first six months of 2011 and 2010, respectively. The quarterly cash dividend was $0.16 per share in the first and second quarter of 2010 and the first quarter of 2011. In the second quarter of 2011, Devon increased the dividend rate to $0.17 per share.

13.  Restructuring Costs 

In the fourth quarter of 2009, Devon announced plans to divest its offshore assets. As of June 30, 2011, Devon had divested all of its U.S. Offshore assets and substantially all of its International assets.

Through the end of the second quarter of 2011, Devon had incurred $204 million of restructuring costs associated with these divestitures. This amount is comprised of $120 million of employee severance costs, $81 million associated with abandoned office leases and $3 million of other miscellaneous costs.

14.  Income Taxes

In the second quarter of 2011, a portion of Devon's foreign earnings were no longer deemed to be permanently reinvested in accordance with accounting principles generally accepted in the United States of America. Accordingly, Devon recognized $725 million of deferred tax expense and $19 million of current income tax expense during the second quarter of 2011 related to assumed repatriations of such earnings under current U.S. tax law. These earnings were primarily related to the gains generated from Devon's International divestiture transactions. Excluding the $744 million of tax expense, Devon's effective income tax rate was 33% in both the second quarter and first six months of 2011, respectively.

15.   Discontinued Operations

In May 2011, Devon completed the divestiture of its operations in Brazil. With the close of the Brazil transaction, Devon has substantially completed its planned offshore divestitures. In aggregate, Devon's U.S. and International offshore sales have generated total proceeds of $10 billion, or approximately $8 billion after-tax, assuming repatriation of a portion of the foreign proceeds under current U.S. tax law.

Revenues related to Devon's discontinued operations totaled $43 million in the first six months of 2011 and $222 million and $434 million in the second quarter and first six months of 2010, respectively. Devon did not have revenues related to its discontinued operations in the second quarter of 2011.

Earnings from discontinued operations in the second quarter and first six months of 2011 and 2010 were largely impacted by gains on Devon's International divestiture transactions. The following table presents the gains on the divestitures according to the quarters in which the divestitures closed in 2011 and 2010. The after-tax amounts in the table below exclude $744 million of income tax expense related to assumed repatriations discussed in Note 14.

The following table presents the main classes of assets and liabilities associated with Devon's discontinued operations.

16.   Earnings Per Share

The following table reconciles earnings from continuing operations and common shares outstanding used in the calculations of basic and diluted earnings per share.

17.   Segment Information

Devon manages its North American onshore operations through distinct operating segments, or divisions, which are defined primarily by geographic areas. For financial reporting purposes, Devon aggregates its United States divisions into one reporting segment due to the similar nature of the businesses. However, Devon's Canadian and International divisions are reported as separate reporting segments primarily due to significant differences in the respective regulatory environments.

____________________________

(1)   Current assets in the Canadian segment include $6.1 billion of cash, cash equivalents and short-term investments that were generated from Devon's International offshore divestiture program and have not been repatriated to the United States.
