Goodwill Impaired Facts And Circumstances Leading To Impairment			The Corporation’s policy is to assess goodwill and other intangibles for impairment on an annual basis during the fourth quarter of each year, and more frequently if events or circumstances lead management to believe that the values of goodwill or other intangibles may be impaired. During the fourth quarter of 2023, management performed a qualitative analysis of the carrying amount of each relevant reporting units’ goodwill and concluded that it is more-likely-than-not that the fair value of the reporting units exceeded their carrying value. This assessment involved identifying the inputs and assumptions that most affect fair value, including evaluating significant and relevant events impacting each reporting entity, and evaluating such factors to determine if a positive assertion can be made that it is more-likely-than-not that the fair value of the reporting units exceeded their carrying amount. As of December 31, 2023, the Corporation concluded that it is more-likely-than-not that the fair value of the reporting units exceeded their carrying value. The Corporation determined that there have been no significant events since the last annual assessment that could indicate potential goodwill impairment on reporting units for which the goodwill is allocated. As a result, no impairment charges for goodwill were recorded during the first quarter of 2024.
