____________________________________________

⁽¹⁾ Amounts have been reclassified to conform with the current year presentation as a result of the segment reorganization discussed in Note 9, Segment Reporting.

Goodwill is tested at least annually for impairment on November 30, or more frequently if events or changes in circumstances indicate that the asset might be impaired. We first perform a qualitative assessment to determine whether it is more likely than not that the fair value of our reporting units is less than their respective carrying value (“Step Zero Analysis”). If the Step Zero Analysis indicates it is more likely than not that the fair value of our reporting units is less than their respective carrying value, an additional impairment assessment is performed (“Step One Analysis”). As a result of the segment reorganization discussed in Note 9, Segment Reporting, we determined the fair value of each of our reporting units to further support our qualitative assessment and determined the more likely than not criteria had not been met, and therefore a Step One Analysis was not required as of March 31, 2019.
