	us-gaap	Use Of Estimates UseOfEstimates	In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenues and expenses for the period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to change are the determination of the allowance for credit losses on loans, the valuation of goodwill and identifiable intangible assets and the accounting for defined benefit pension plans.
