(1) Related to measurement period adjustments for the Scapa acquisition.

(2) Goodwill with a carrying amount of $2.1 million was allocated to the disposal group classified as held for sale as of March 31, 2022 and subsequently impaired. Goodwill was allocated to the disposal group on the basis of relative fair value, primarily utilizing Level 3 inputs which included forecasted future cash flows. We considered the planned divestiture of this business as a potential indicator that the fair value of the AMS reporting unit may be below its carrying amount and performed a qualitative impairment assessment. As a result of this assessment, we concluded that as of March 31, 2022 the fair value of the reporting unit was in excess of its carrying value and therefore no impairment was identified or recognized.
