Concentrations Of Credit [Abstract]
Concentrations Of Credit	18.CONCENTRATIONS OF CREDIT All of the Bank’s loans, commitments, and standby letters of credit have been granted to customers in the Bank’s primary market areas of the Western New York and the Finger Lakes Region of New York State. Investments in state and municipal securities also involve governmental entities within the Bank’s primary market area. The concentrations of credit by type of loan are set forth in Note 4 to these Consolidated Financial Statements, "Loans and the Allowance for Credit Losses." The distribution of commitments to extend credit approximates the distribution of loans outstanding. Standby letters of credit were granted to commercial borrowers. The Bank, as a matter of policy, does not extend credit to any single borrower or group in excess of 15% of capital.

The entire disclosure for any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. This disclosure informs financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date.
