Goodwill and Intangible Assets Disclosure [Abstract] |
Impairment | ImpairmentAs of June 30, 2020 and as part of its periodic review of the carrying value of long-lived assets, the Company assessed its long-lived assets for potential impairment. In assessing impairment of its APT segment's and certain other long-lived asset groups, the Company considered factors such as the significant decline in both the APT segment's trailing twelve months revenues and current and future years’ forecasted revenues. These factors were largely due to the significant drop in coal-fired power dispatch that began in 2019 amid historically low prices of alternative power generation sources such as natural gas, leading to an increase in natural gas usage as well as other competing energy sources. As of June 30, 2020, the Company completed an undiscounted cash flow analysis of its APT segment's long-lived assets (the "Asset Group"), which are comprised of its manufacturing plant (the "Red River Plant") and related assets and its lignite mine assets, and estimated the undiscounted cash flows from the Asset Group at $54.7 million, which was less than the carrying value of the Asset Group of $58.3 million. Accordingly, the Company completed an assessment of the Asset Group’s fair value and estimated the fair value of the Asset Group at $32.2 million. This resulted in an impairment and write-down of the Asset Group (the "Impairment Charge") of $26.1 million as of June 30, 2020, which is reflected as "Impairment of long-lived assets" in the Condensed Consolidated Statements of Operations for the nine months ended September 30, 2020. The following table summarizes the allocation to the Asset Group of the Impairment Charge of $26.1 million recorded as of June 30, 2020:
(in thousands) |  |
Property, plant and equipment, net |  | $ | 18,986 |
Intangible assets, net |  | 1,445 |
Other long-term assets, net |  | 5,672 |
Total impairment |  | $ | 26,103 |
The Company engaged an independent third party to perform the valuation of the Asset Group in order to determine the estimated fair value of the Asset Group. This valuation was based on the use of several established valuation models including an expected future discounted cash flow model based on cash flows expected to be generated by market participants discounted at the risk-free rate of interest. Because of the continued future uncertainty surrounding the level of coal-fired dispatch, the impact of volatile natural gas prices and other estimates impacting the expected future cash flow, it is reasonably possible that the expected future cash flows may change in the near term and may result in the Company recording additional impairment of the Asset Group. As of September 30, 2021, the Company determined that there was no additional impairment of the Asset Group.
