CY2020	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.Continued uncertainty regarding the severity and duration of the COVID-19 pandemic and related economic effects will continue to affect the accounting for credit losses. It also is possible that asset quality could worsen, expenses associated with collection efforts could increase and loan charge-offs could increase.
