Summary Of Significant Accounting Policies
Summary Of Significant Accounting Policies

1. Summary of Significant Accounting Policies

     The accompanying unaudited 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 financial statements and notes should be read in conjunction with the accompanying financial statements and notes included in Devon's 2011 Annual Report on Form 10-K.

     The accompanying unaudited interim financial statements furnished in this report reflect all adjustments that are, in the opinion of management, necessary to a fair statement of Devon's results of operations and cash flows for the three-month periods ended March 31, 2012 and 2011 and Devon's financial position as of March 31, 2012.

Derivative Financial Instruments
Derivative Financial Instruments

2. Derivative Financial Instruments

Objectives and Strategies

     Devon periodically enters into derivative financial instruments with respect to a portion of its oil, gas and NGL production that hedge the future prices received. These instruments are used to manage the inherent uncertainty of future revenues due to commodity price volatility. Devon's derivative financial instruments typically include financial price swaps, basis swaps, costless price collars and call options.

     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 periodically enters into foreign exchange forward contracts to manage its exposure to fluctuations in exchange rates.

     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.

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 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 certain credit rating levels. As of March 31, 2012, the credit ratings of all Devon's counterparties were within established guidelines.

Commitments And Contingencies
Commitments And Contingencies

16. Commitments and Contingencies

     Devon is party to various legal actions arising in the normal course of business. Matters that are probable of unfavorable outcome to Devon and which 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. None of the actions are believed by management to involve future amounts that would be material to Devon's financial position or results of operations after consideration of recorded accruals. Actual amounts could differ materially from management's estimates.

Royalty Matters

     Numerous natural gas producers and related parties, including Devon, have been named in various lawsuits alleging violation of the federal False Claims Act. The suits allege that the producers and related parties used below-market prices, improper deductions, improper measurement techniques and transactions with affiliates, which resulted in underpayment of royalties in connection with natural gas and NGLs produced and sold. Devon does not currently believe that it is subject to material exposure with respect to such royalty matters.

Environmental Matters

     Devon is subject to certain laws and regulations relating to environmental remediation activities associated with past operations, such as the Comprehensive Environmental Response, Compensation, and Liability Act and similar state statutes. In response to liabilities associated with these activities, loss accruals primarily consist of estimated uninsured remediation costs. Devon's monetary exposure for environmental matters is not expected to be material.

Chief Redemption Matters

     In 2006, Devon acquired Chief Holdings LLC ("Chief") from the owners of Chief, including Trevor Rees-Jones, the majority owner of Chief. In 2008, a former owner of Chief filed a petition against Rees-Jones, as the former majority owner of Chief, and Devon, as Chief's successor pursuant to the 2006 acquisition. The petition claimed, among other things, violations of the Texas Securities Act, fraud and breaches of Rees-Jones' fiduciary responsibility to the former owner in connection with Chief's 2004 redemption of the owner's minority ownership stake in Chief.

     On June 20, 2011, a court issued a judgment against Rees-Jones for $196 million, of which $133 million of the judgment was also issued against Devon. Both Rees-Jones and Devon are appealing the judgment. If the appeal is unsuccessful, Devon can and will seek full payment of the judgment and any related interest, costs and expenses from Rees-Jones pursuant to an existing indemnification agreement between Rees-Jones, certain other parties and Devon. Devon does not expect to have any net exposure as a result of the judgment. However, because Devon does not have a legal right of set off with respect to the judgment, Devon has recorded in the accompanying March 31, 2012 and December 31, 2011, balance sheets both a $133 million liability relating to the judgment with an offsetting $133 million receivable relating to its right to be indemnified by Rees-Jones and certain other parties pursuant to the indemnification agreement.

Other Matters

     Devon is involved in other various routine legal proceedings incidental to its business. However, to Devon's knowledge, there were no other material pending legal proceedings to which Devon is a party or to which any of its property is subject.

Fair Value Measurements

17. Fair Value Measurements

     The following tables provide 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 payables and accrued expenses included in the accompanying balance sheets approximated fair value at March 31, 2012 and December 31, 2011. Therefore, such financial assets and liabilities are not presented in the following table.

Debt $ (9,780 ) $ (11,380 ) $ $ (11,295 ) $ (85 )

 

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

Level 1 Fair Value Measurements

     Cash equivalents and short-term investments — Amounts consist primarily of U.S. and Canadian Treasury securities and money market investments. The fair value approximates the carrying value.

Level 2 Fair Value Measurements

     Cash equivalents and short-term investments — Amounts consist primarily of commercial paper investments. The fair value is based upon quotes from brokers, which approximate the carrying value.

     Commodity, interest rate and foreign exchange derivatives — The fair values of commodity and interest rate derivatives are estimated using internal discounted cash flow calculations based upon forward curves and quotes obtained from brokers for contracts with similar terms or quotes obtained from counterparties to the agreements.

     Debt — Devon's debt instruments do not actively trade in an established market. The fair values of its fixed-rate debt are estimated based on rates available for debt with similar terms and maturity. The fair values of Devon's variable-rate commercial paper and credit facility borrowings are the carrying values.

Level 3 Fair Value Measurements

     Long-term investments — Devon's long-term investments presented in the tables above consisted entirely of auction rate securities. Due to auction failures and the lack of an active market for Devon's auction rate securities, quoted market prices for these securities were not available. Therefore, Devon used valuation techniques that rely on unobservable inputs to estimate the fair values of its long-term auction rate securities. These inputs were based on the AAA credit rating of the securities, the probability of full repayment of the securities considering the U.S. government guarantees substantially all of the underlying student loans, the collection of all accrued interest to date and continued receipts of principal at par. As a result of using these inputs, Devon concluded the estimated fair values of its long-term auction rate securities approximated the par values as of March 31, 2012 and December 31, 2011. There were no changes in the fair value of these instruments in the three month periods ended March 31, 2012 and 2011, respectively.

     Debt — Devon's Level 3 debt consisted of a non-interest bearing promissory note. Due to the lack of an active market, quoted marked prices for this note, or similar notes, were not available. Therefore, Devon used valuation techniques that rely on unobservable inputs to estimate the fair value of its promissory note. The fair value of this debt is estimated using internal discounted cash flow calculations based upon estimated future payment schedules and a 3.125% interest rate.

Discontinued Operations
Discontinued Operations

18. Discontinued Operations

     In March 2012, Devon received $71 million upon closing the divestiture of its operations in Angola, which completed Devon's offshore divestiture program that was announced in November 2009. In aggregate, Devon's U.S. and International offshore divestitures have generated total proceeds of $10.1 billion, or approximately $8 billion after-tax, assuming repatriation of a substantial portion of the foreign proceeds under current U.S. tax law.

     Revenues related to Devon's discontinued operations totaled $43 million in the three months ended March 31, 2011. Devon did not have revenues related to its discontinued operations during the first three months of 2012. Earnings (loss) from discontinued operations before income taxes totaled $(16) million and $30 million in the three months ended March 31, 2012 and March 31, 2011, respectively.

     The following table presents the main classes of assets and liabilities associated with Devon's discontinued operations at December 31, 2011. Devon did not have assets or liabilities held for sale at March 31, 2012.

Segment Information
Segment Information

19. Segment Information

     Devon manages its operations through distinct operating segments, or divisions, which are defined primarily by geographic areas. For financial reporting purposes, Devon aggregates its U.S. divisions into one reporting segment due to the similar nature of the businesses. However, Devon's Canadian division is reported as separate reporting segment primarily due to the significant differences between the U.S. and Canadian regulatory environments. Devon's segments are all primarily engaged in oil and gas producing activities. Revenues are all from external customers.
