The Company performed annual impairment testing as of the first day of its fourth fiscal quarter and concluded that there were no impairments of goodwill as the estimated fair value of each reporting unit exceeded its carrying value.

During fiscal 2021, the Company changed its internal organization structure such that AeroGrow is now managed by and reported within the U.S. Consumer segment. Within the U.S. Consumer segment, AeroGrow is integrated into the Company’s overall direct to consumer focus and strategy. AeroGrow was previously managed by and reported within the Hawthorne segment. This change in organization structure resulted in a change in the Company’s reporting units. As a result, goodwill included in impacted reporting units was reallocated using a relative fair value approach, resulting in $15.8 of goodwill reallocated from the Hawthorne segment to the U.S. Consumer segment during fiscal 2021. In addition, the Company completed an assessment of potential goodwill impairment immediately before and after the reallocation and determined that no impairment existed.
