Long-Lived Asset Impairment [Abstract]

IMPAIRMENT - WOOD TREATMENT

IMPAIRMENT OF LONG-LIVED ASSETS

As a result of the previously announced planned facilities closures due to the strategic decision to exit the wood treatment business, the Company previously adjusted the remaining assets’ useful lives such that they do not extend beyond the expected closure dates of the facilities. The Company tested the recoverability of its long-lived assets and determined the carrying amount of the assets exceeded the sum of the expected undiscounted future cash flows, and as a result, we compared the fair value of the wood treatment asset group, which was determined based on a discounted cash flow model, to its carrying value. As a result, the Company recorded non-cash, pre-tax impairment charges of $3,266, $2,314 and $67,372 for the years ended September 30, 2021, 2020 and 2019, respectively. There was no remaining carrying value of definite-lived intangible assets or Property, plant and equipment as of September 30, 2021.

Key assumptions in testing the assets for recoverability and development of the fair value of the asset group included projected future revenue and gross margin. As the inputs for testing recoverability, including estimates of future revenue and gross margin, are not generally observable in active markets, the Company considers such measurements to be Level 3 measurements in the fair value hierarchy. The duration of the future revenue and gross margin estimates are limited to the period through the closure dates.

IMPAIRMENT OF GOODWILL

The fair value of the wood treatment reporting unit, which was determined based on a discounted cash flow model, did not exceed the carrying value of the reporting unit. Key assumptions in our goodwill impairment test included projected future revenue and gross margin. As a result, the Company recorded a non-cash, pre-tax impairment charge of $25,576 for the year ended September 30, 2021.

As the Company approaches the closure dates of the facilities and there are finite estimated future cash flows, the carrying value of the wood treatment reporting unit will not be recoverable, resulting in future impairments of goodwill. The remaining carrying value of the wood treatment reporting unit as of September 30, 2021 includes $9.4 million of goodwill, which will be periodically impaired through the closure dates, resulting in no fair value ascribed to the wood treatment business by the dates of closure. The amount of the periodic impairments will vary depending on the timing of the remaining future cash flows of the business and carrying value of the reporting unit at each reporting period.
