Goodwill and intangible assets [Abstract] |
Goodwill and Intangible Assets Disclosure [Text Block] | Goodwill and Other Intangible Assets Goodwill Goodwill is the excess purchase price remaining from an acquisition after an allocation of purchase price has been made to identifiable assets acquired and liabilities assumed based on estimated fair values. The Company transitioned to the new segment reporting structure effective January 1, 2022 which resulted in certain changes to our operating segments and reporting units. We have allocated goodwill to our reporting units using a relative fair value approach. In addition, we completed an assessment of any potential goodwill impairment for all reporting units immediately prior and subsequent to the reallocation and determined that no impairment existed. The changes in the carrying value of goodwill for our reportable segments, MD&E, IA&C and SC&E, for the years ended December 31, 2022 and 2021 are listed below.
