Reduction in Value of Assets [Abstract]
Reduction in Value of Assets	(14) Reduction in Value of Assets Long-lived assets, such as property, plant and equipment and purchased intangibles subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is assessed by a comparison of the carrying amount of such assets to their fair value calculated, in part, by the estimated undiscounted future cash flows expected to be generated by the assets. Cash flow estimates are based upon, among other things, historical results adjusted to reflect the best estimate of future market rates, utilization levels, and operating performance. Estimates of cash flows may differ from actual cash flows due to, among other things, changes in economic conditions or changes in an asset’s operating performance. Our assets are grouped by line of business or division for the impairment testing, which represents the lowest level of identifiable cash flows. If the asset grouping’s fair value is less than the carrying amount of the asset grouping, impairment losses are recorded in the amount by which the carrying amount of asset grouping exceeds the fair value. The estimate of fair value represents our best estimate based on industry trends and reference to market transactions and is subject to variability. During the first quarter of 2020, in line with the rapidly changing market conditions, our market capitalization deteriorated. We determined that these events constituted a triggering event that required us to review the recoverability of our long-lived assets and to perform an interim goodwill impairment as of March 31, 2020. During the Prior Predecessor Period, we recorded a reduction in value of assets totaling $16.5 million which related to property, plant and equipment in the Production Services and Technical Solutions segments.

Long-lived assets, such as property, plant and equipment and purchased intangibles subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable.
