1.There are no accumulated impairment amounts at September 30, 2020 or 2019.
During fiscal 2021, the Company recorded impairment charges related to the PIM and wood treatment reporting units within the Performance Materials segment. As a result of lower than anticipated recovery from a drop in demand for our PIM products due to the ongoing impact of the COVID-19 pandemic (“Pandemic”), combined with a near-to-mid term increase in raw material cost for the PIM business, we determined that it was more likely than not that the fair value of the PIM reporting unit was below its carrying value, requiring the PIM reporting unit to be tested for impairment at March 31, 2021. Based on the results of the interim impairment test, the Company concluded that the carrying value of the PIM reporting unit exceeded the estimated fair value, and recognized a non-cash, pre-tax goodwill impairment charge of $201,550. The goodwill impairment charge is included in the Performance Materials segment and presented within Impairment charges, and the related tax benefit of $23,539 is included in the Provision for income taxes in the Consolidated Statements of (Loss) Income for the year ended September 30, 2021.
In connection with our annual impairment assessment, the estimated fair value of the PIM reporting unit was determined to exceed the carrying value by approximately 5% as of July 1, 2021 and no additional impairment was recognized. The most significant estimates and assumptions inherent in the discounted cash flows model are the forecasted revenue growth rate, forecasted gross margin, the discount rate and the terminal growth rate. These assumptions are classified as level 3 inputs. The Company’s projections for revenue and gross margin are based on the Company’s multiyear forecast, which reflects a recovery from the Pandemic during the forecast period and normalization of raw material costs. The discount rate was based on an estimated weighted average cost of capital (“WACC”) for the PIM reporting unit. The components of WACC are the cost of equity and the cost of debt, each of which requires judgment by management to estimate. The company developed its cost of equity estimate based on perceived risks and predictability of future cash flows.
The remaining carrying value of the PIM reporting unit as of September 30, 2021 of $566,300 includes $118,235 of goodwill and $46,000 of indefinite lived intangible assets.
Additionally, the Company recorded non-cash, pre-tax goodwill impairment charge of $25,576 for the year ended September 30, 2021, related to the wood treatment asset group and reporting unit due to the previously announced planned closure of the facilities. See Note 10 of this Annual Report on Form 10-K for discussion of the wood treatment impairment.

We continue to actively monitor the industries in which we operate and our businesses’ performance for indicators of potential impairment. If current global macroeconomic conditions related to the Pandemic persist and continue to adversely impact our Company, we may have future additional impairments of goodwill or other intangible assets. Potential future impairments could be material to the Company’s Consolidated Balance Sheets and to the Consolidated Statements of (Loss) Income, but we do not expect them to affect the Company’s reported Net cash provided by operating activities.
