Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill During the first quarter of 2020, our market capitalization declined to a level that was less than the net book value of our stockholders’ equity. The decline in market capitalization was a triggering event that caused us to perform a goodwill impairment analysis as of March 31, 2020. The goodwill impairment analysis required significant judgments to calculate the fair value for the Power Solutions reporting unit, including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term growth rate for the operating segment, and determination of weighted average cost of capital. Our forecasts used in the goodwill impairment analysis reflected our expectations of declines in sales resulting from COVID-19. Significant assumptions and estimates are involved in the application of the discounted cash flow model to forecast operating cash flows, including market growth and market share, sales volumes and prices, costs to produce, discount rate, and estimated capital needs. Management considers historical experience and all available information at the time the fair values of its reporting units are estimated. Assumptions in estimating future cash flows are subject to a high degree of judgment and complexity. The carrying value of the Power Solutions reporting unit exceeded the estimated fair value as of the March 31, 2020, analysis. As a result of our analysis, we recorded an impairment loss on goodwill of $92.9 million to the “Goodwill impairment” line on the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). As of June 30, 2021, and December 31, 2020, there was no remaining goodwill balance.
