CY2022	us-gaap	Use Of Estimates UseOfEstimates	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. In particular, estimates and assumptions are used in measuring the fair value of certain financial instruments, determining the appropriateness of the allowance for loan and lease losses (“allowance”), evaluating potential other-than-temporary securities impairment, assessing the ability to realize deferred tax assets, and the valuation of share-based payment awards. Estimates and assumptions are based on available information and judgment; therefore actual results could differ from those estimates.

The Company monitors its entire loan portfolio on a regular basis and considers numerous factors including (i) end-of-period loan levels and portfolio composition, (ii) observable trends in non-performing loans, (iii) the Company’s historical loan loss experience, (iv) known and inherent risks in the portfolio, (v) underwriting practices, (vi) adverse situations which may affect the borrower’s ability to repay, (vii) the estimated value and sufficiency of any underlying collateral, (viii) credit risk grading assessments, (ix) loan impairment, and (x) economic conditions.</span></div><div style="margin-top:12pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. Additions to the allowance are charged to expense, and realized losses, net of recoveries, are charged to the allowance. Based on the determination of management, the overall level of allowance is periodically adjusted to account for the inherent and specific risks within the entire portfolio. Based on review of the classified loans and the overall allowance levels as they relate to the entire loan portfolio at December 31, 2022, management believes the allowance is adequate.</span></div><div style="margin-top:12pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Generally, a loan is considered for charge-off when it is in default of either principal or interest after 90 days or more. In addition to delinquency criteria, other triggering events may include, but are not limited to, notice of bankruptcy by the borrower or guarantor, death of the borrower, and deficiency balance from the sale of collateral. </span></div><div style="margin-top:12pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Some financial instruments, such as loan commitments, credit lines, letters of credit, and overdraft protection, are issued to meet customer financing needs. These are agreements to provide credit or to support the credit of others, as long as conditions established in the contract are met, and usually have expiration dates. Commitments may expire without being used. Off-balance sheet risk to credit loss exists up to the face amount of these instruments, although material losses are not anticipated. The same credit policies are used to make such commitments as are used for loans, often including obtaining collateral at exercise of the commitment. An allowance is calculated and recorded in other liabilities within the Consolidated Statements of Financial Condition.</span></div><div style="margin-top:12pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">While management uses available information to recognize losses on loans, future additions or reductions to the allowance may be necessary due to changes in one or more evaluation factors; management’s assumptions as to rates of default, loss or recovery, or management’s intent with regard to disposition. A shift in lending strategy may warrant a change in the allowance due to a changing credit risk profile. In addition, various regulatory agencies, as an integral part of the examination process, periodically review the Company’s allowance. Such agencies may require the Company to recognize additions to, or charge-offs against, the allowance based on their judgment about information available to them at the time of their examination.</span></div>
