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 part of our annual Step Zero Analysis performed in 2022, we determined that due to certain qualitative factors and the recent performance of our Europe Surface Transportation reporting unit that the more likely than not criteria had been met, and therefore a Step One Analysis was completed for this reporting unit. Our Step Zero Analysis did not indicate that the more likely than not criteria was met for any other reporting units and therefore a Step One Analysis was not completed for those reporting units. As a result of our Step One Analysis for Europe Surface Transportation, we determined that the fair value was greater than the reporting unit's respective carrying value and as such the goodwill balance was not impaired.
