The Company performed its annual impairment analysis for the Vinyls reporting units during the second quarter of 2021 and determined that it is more likely than not that the fair value of each of the Vinyls reporting units exceeds its carrying value. Factors considered in the qualitative assessment included macroeconomic conditions, industry and market considerations, cost factors, current and projected financial performance, changes in management or strategy and market capitalization.
