Divestitures	2.Divestitures In February 2019, Devon announced its intent to separate its Canadian business and Barnett Shale assets from the Company, based on authorizations provided by its Board of Directors. On June 27, 2019, Devon completed the sale of substantially all of its oil and gas assets and operations in Canada to Canadian Natural Resources Limited for proceeds, net of purchase price adjustments, of $2.6 billion ($3.4 billion Canadian dollars), and recognized a pre-tax gain of $223 million ($480 million, net of tax). Included within this gain is a $34 million ($20 million, net of tax) adjustment to the gain in the third quarter of 2019 related to an interim post closing settlement with Canadian Natural Resources Limited with final closing expected in the fourth quarter of 2019. As a part of the transaction, $436 million of asset retirement obligations were assumed by Canadian Natural Resources Limited. In aggregate, the total estimated proved reserves associated with these assets were approximately 400 MMBoe, or 21% of total proved reserves. In conjunction with the Canadian divestiture, Devon recognized approximately $280 million of restructuring and asset impairment related charges. These costs relate to personnel, office lease abandonment and a firm transportation agreement abandonment. Additional information on these discontinued operations can be found in Note 18. Devon is evaluating multiple methods of separation for the Barnett Shale assets, including a potential sale, merger or spin-off. Estimated proved reserves associated with Devon’s Barnett Shale assets are approximately 46% of total U.S. proved reserves. As of September 30, 2019, Devon’s Barnett Shale assets were considered held for use and had a net carrying value of approximately $1.4 billion. Devon evaluated its Barnett Shale assets for impairment as of September 30, 2019, and concluded an impairment was not required. This conclusion was based on probability-weighted computations applied to fair value estimates of held for use and held for sale options under evaluation. Although an impairment was not required to be recognized at September 30, 2019, should Devon enter into a sale transaction at current market estimates for its Barnett Shale assets, Devon would recognize an impairment based on the estimated transaction value as compared to the carrying value. Devon anticipates reporting all information for its Barnett Shale assets as discontinued operations when all the requisite criteria are met for such financial statement presentation. In the first quarter of 2019, Devon received proceeds of approximately $300 million and recognized a $44 million net gain on asset dispositions, primarily from sales of non-core assets in the Permian Basin. In aggregate, the total estimated proved reserves associated with these divested assets were approximately 25 MMBoe, or less than 2% of total U.S. proved reserves. As of December 31, 2018, assets and liabilities associated with these divested assets were classified as held for sale in the accompanying consolidated balance sheet. During the second quarter of 2018, Devon sold a portion of its Barnett Shale assets, primarily located in Johnson County for $553 million. Estimated proved reserves associated with these assets were approximately 10% of total proved reserves. The transaction resulted in an adjustment to Devon’s capitalized costs with no gain recognized in the consolidated statement of earnings. In conjunction with the divestiture, Devon settled certain gas processing contracts and recognized an approximately $40 million settlement expense, which is included in asset dispositions within the consolidated statement of earnings. During the third quarter of 2018, Devon completed the sale of its aggregate ownership interests in EnLink and the General Partner for $3.125 billion and recognized a gain of approximately $2.6 billion ($2.2 billion after-tax). The proceeds from the sale were utilized to increase Devon’s share repurchase program, which is discussed further in Note 17. Additional information on these discontinued operations can be found in Note 18.
