In 2019, Devon announced that it had entered into an agreement to sell its Barnett Shale assets to BKV and subsequently amended the agreement in April 2020. Under the amended terms, Devon has agreed to sell its Barnett Shale assets for $570 million in cash, before purchase price adjustments, at closing, which was extended to December 31, 2020. 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 commences on January 1, 2021 and has a term of four years. Under the terms of the agreement, Devon received the deposit funds of $170 million in April 2020. The deposit is being held by Devon pursuant to the terms of the sale agreement, which only requires Devon to return such funds to BKV in the event the transaction does not close as a result of Devon’s breach of its closing obligations.

In connection with the announced sale of its Barnett Shale assets, approximately $88 million of the U.S. reporting unit goodwill was allocated to the Barnett Shale assets. Additionally, Devon ceased depreciation for all property, plant and equipment classified as assets held for sale on the date the sales agreement was approved by the Board of Directors. Devon also recognized a $748 million asset impairment in the fourth quarter of 2019 related to these assets, primarily due to the difference between the net carrying value and the purchase price, net of estimated customary purchase price adjustments. During the first quarter of 2020, Devon adjusted the estimated impairment $179 million, primarily due to the amended agreement terms. The valuation of the future contingent earnout payments included in the March 31, 2020 Barnett Shale impairment computation was $41 million. The value was derived utilizing a Monte Carlo valuation model and qualifies as a level 3 fair value measurement.

As of March 31, 2020, Devon has restricted approximately $25 million to fund obligations in connection with the abandonment of certain gas processing contracts related to the 2018 divestitures. Cash payments for these charges total approximately $2 million per quarter.

On June 27, 2019, Devon completed the sale of its Canadian business for $2.6 billion ($3.4 billion Canadian dollars), net of purchase price adjustments, and recognized a pre-tax gain of $223 million ($425 million net of tax, primarily due to a significant deferred tax benefit). Current (cash) income tax associated with the sale was approximately $150 million and was paid in the first quarter of 2020. The disposition of substantially all of Devon’s Canadian oil and gas assets resulted in Devon releasing its historical cumulative foreign currency translation adjustment of $1.2 billion from accumulated other comprehensive earnings to be included within the gain computation. The historical cumulative foreign currency translation portion of the gain is not taxable.

During the third quarter of 2019, Devon utilized a portion of the sales proceeds to early retire its $500 million of the 4.00% senior notes due July 15, 2021 and $1.0 billion of the 3.25% senior notes due May 15, 2022. Devon recognized a charge on the early retirement of these notes consisting of $52 million in cash retirement costs and $6 million of noncash charges.

As of March 31, 2020, $175 million of the Canadian cash balance is restricted for funding other obligations retained related to the Canadian business and is classified as cash restricted for discontinued operations on the consolidated balance sheets. The remaining obligations consist of a firm transportation agreement and office leases. Cash payments for these charges total approximately $6 million per quarter.
