Goodwill is not amortized, but is tested for impairment at the reporting unit level using either a qualitative or quantitative assessment on an annual basis during the fourth quarter of each fiscal year, and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Impairment of goodwill is measured at the reporting unit level by comparing the reporting unit’s carrying amount, including goodwill, to the fair market value of the reporting unit. As of May 1, 2022, there was no indication of impairment of the Company's goodwill balances and goodwill excluded amounts reclassified to assets held for sale. See Note 2, Divestiture, for additional information.
