Goodwill Disclosure [Text Block]	Note 6. Goodwill Goodwill arose in connection with four acquisitions in previous periods. Accounting standards allow for goodwill to be tested for impairment by performing a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying value. There was no impairment of the carrying amount of goodwill in 2023 and 2022.
