CY2024	us-gaap	Use Of Estimates UseOfEstimates	The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities, as of the date of the consolidated balance sheets, and the reported amounts of income and expenses during the reporting periods. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near-term relate to the determination of the allowance for credit losses ("ACL"), the valuation of loan servicing rights, the valuation of assets acquired and liabilities assumed in acquisitions and the valuation of goodwill for potential impairment.
