With the adoption of fresh start accounting, the Company recorded its property, plant and equipment at fair value as of the Emergence Date (refer to Note 3—Fresh Start Accounting).

Impairment

The Company reviews its property, plant and equipment for impairment by asset group whenever events and circumstances indicate that a decline in the recoverability of their carrying value may have occurred. If events occur that indicate an asset group may not be recoverable, the asset group is tested for recoverability. The Company determined no impairment indicators existed for its asset groups as of December 31, 2020 (Successor).

Proved oil and gas properties. The Company estimates the expected undiscounted future cash flows of its proved oil and gas properties by field and then compares such amount to the carrying amount of the proved oil and gas properties in the applicable field to determine if the carrying amount is recoverable. If the carrying amount exceeds the estimated undiscounted future cash flows, the Company will adjust the carrying amount of the proved oil and gas properties to fair value. The factors used to determine fair value are subject to management’s judgment and expertise and include, but are not limited to, recent sales prices of comparable properties, the present value of future cash flows net of estimated operating and development costs using estimates of proved reserves, future commodity pricing, future production estimates, anticipated capital expenditures and various discount rates commensurate with the risk and current market conditions associated with realizing the expected cash flows projected. These assumptions represent Level 3 inputs, as further discussed under Note 9—Fair Value Measurements.

As a result of the significant decline in expected future commodity prices coupled with the Company’s liquidity concerns, and the resulting decrease in its estimated proved reserves, the Company reviewed its proved oil and gas properties in both the Williston Basin and the Delaware Basin for impairment in the first quarter of 2020. During the period from January 1, 2020 through November 19, 2020 (Predecessor), the Company recorded impairment charges of $4.4 billion, including $3.8 billion related to the Williston Basin and $637.3 million related to the Permian Basin, to reduce the carrying values of its proved oil and gas properties to their estimated fair values. For the years ended December 31, 2019 and 2018 (Predecessor), the Company did not record impairment of proved oil and gas properties.

Unproved oil and gas properties. The Company assessed its unproved oil and gas properties for impairment and recorded impairment charges on its unproved oil and gas properties of $401.1 million for the period from January 1, 2020 through November 19, 2020 (Predecessor), and $5.4 million and $0.9 million for the years ended December 31, 2019 and 2018 (Predecessor), respectively, as a result of expiring leases, periodic assessments and drilling plan uncertainty on certain acreage of unproved properties.

Other property and equipment. The Company reviews its other property and equipment for impairment whenever events and circumstances indicate that a decline in the recoverability of their carrying value may have occurred. Due to the significant decline in expected future commodity prices during the first quarter of 2020, the Company and other crude oil and natural gas producers changed their development plans, which resulted in lower forecasted throughput volumes for the Company’s midstream assets. As a result, the Company reviewed its midstream assets, grouped by commodity for each basin, for impairment as of March 31, 2020. The carrying amounts exceeded the estimated undiscounted future cash flows for certain midstream asset groups in the Williston Basin and the Delaware Basin, and as a result, the Company recorded impairment charges of $108.3 million during the period from January 1, 2020 through November 19, 2020 (Predecessor) to reduce the carrying values of these midstream assets to their estimated fair values. In addition, during the period from January 1, 2020 through November 19, 2020 (Predecessor), the Company recorded impairment charge of $1.6 million on certain midstream equipment, including a right-of-use asset associated with mechanical refrigeration units leased at the Company’s natural gas processing complex in the Williston Basin. No impairment charges were recorded on the Company’s midstream assets for the years ended December 31, 2019 and 2018 (Predecessor).
