During the first quarter of fiscal 2021, we changed our organizational structure resulting in three operating segments: Intelligent Devices, Software & Control, and Lifecycle Services. This change also resulted in the identification of new reporting units. We reassigned our goodwill balances to reflect this new structure using the relative fair value allocation approach required under U.S. GAAP. Under this approach, the fair values of each of our new reporting units were compared to the total fair value of their prior respective reporting units immediately prior to the reorganization to arrive at the reassigned goodwill balances. We determined the reporting unit fair values using the same approach for quantitative goodwill impairment tests described in Note 1 to the Consolidated Financial Statements. We also tested goodwill at the affected reporting units for impairment prior to and subsequent to the reassignment of goodwill and concluded that goodwill was not impaired.

We perform our annual evaluation of goodwill and indefinite life intangible assets for impairment during the second quarter of each year, or more frequently if events or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. We assessed the changes in events and circumstances subsequent to our annual test and concluded that no triggering events which would require interim quantitative testing occurred except as described above.
