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. 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 performed our annual evaluation of goodwill and indefinite life intangible assets for impairment during the second quarter of 2021 and concluded that these assets are not impaired. Refer to Note 1 for additional information on our annual impairment evaluation.
