Specific valuation allowances are established based on management’s analysis of individually impaired loans. Factors considered by management in determining impairment include payment status, evaluations of the underlying collateral, expected cash flows, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. If a loan is determined to be impaired and is placed on non-accrual status, all future payments received are applied to principal and a portion of the allowance is allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral.</span></div><div style="margin-top:8pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The general component covers non-impaired loans and is based on historical loss experience adjusted for current factors. Loans not impaired but classified as substandard and special mention use a historical loss factor on a rolling five year history of net losses. For all other unclassified loans, the historical loss experience is determined by portfolio class and is based on the actual loss history experienced by the Bank over the most recent two years. This actual loss experience is supplemented with other qualitative factors based on the risks present for each portfolio class. These qualitative factors include consideration of the following: (1) lending policies and procedures, including underwriting standards and collection, charge-off and recovery policies, (2) national and local economic and business conditions and developments, including the condition of various market segments, (3) loan profiles and volume of the portfolio, (4) the experience, ability, and depth of lending management and staff, (5) the volume and severity of past due, classified and watch-list loans, non-accrual loans, troubled debt restructurings, and other modifications (6) the quality of the Bank’s loan review system and the degree of oversight by the Bank’s Board of Directors, (7) collateral related issues: secured vs. unsecured, type, declining valuation environment and trend of other related factors, (8) the existence and effect of any concentrations of credit, and changes in the level of such concentrations, (9) the effect of external factors, such as competition and legal and regulatory requirements, on the level of estimated credit losses in the Bank’s current portfolio and (10) the impact of the global economy.</span></div><div style="margin-top:8pt;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 for loan losses is increased through a provision for loan losses charged to operations. Loans are charged against the allowance for loan losses when management believes that the collectability of all or a portion of the principal is unlikely. Management's evaluation of the adequacy of the allowance for loan losses is performed on a periodic basis and takes into consideration such factors as the credit risk grade assigned to the loan, historical loan loss experience and review of specific impaired loans. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions.</span></div>

SVB was placed into receivership on March 10, 2023, marking the second largest bank failure in U.S. history. Signature Bank was placed into receivership on March 12, 2023, marking the third largest bank failure in U.S. history. Both banks appear to have had high ratios of uninsured deposits to total deposits, when compared to industry average. These failures underscore the importance of maintaining access to diverse sources of funding. </span></div><div style="margin-top:8pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Market conditions and external factors may unpredictably impact the competitive landscape for deposits in the banking industry. Additionally, the rising interest rate environment has increased competition for liquidity and the premium at which liquidity is available to meet funding needs. The Corporation believes the sources of liquidity presented in the Audited Consolidated Financial Statements and the Notes to the Audited Consolidated Financial Statements are sufficient to meet its needs on the balance sheet date. </span></div><div style="margin-top:8pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">An unexpected influx of withdrawals of deposits could adversely impact the Corporation's ability to rely on organic deposits to primarily fund its operations, potentially requiring greater reliance on secondary sources of liquidity to meet withdrawal demands or to fund continuing operations. These sources may include proceeds from Federal Home Loan Bank advances, sales of investment securities and loans, federal funds lines of credit from correspondent banks, and out-of-market time deposits. Important Accounting Policy ramifications of such events are outlined in the previous sections of Note 1, and subsequently in the relevant Notes to the Consolidated Financial Statements. </span></div><div style="margin-top:8pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In response to these events, the Treasury Department, Federal Reserve, and FDIC jointly announced the Bank Term Funding Program (BTFP) on March 12, 2023. This program aims to enhance liquidity by allowing institutions to pledge certain securities at the par value of the securities, and at a borrowing rate of ten basis points over the one-year overnight index swap rate. The BTFP is available to eligible U.S. federally insured depository institutions, with advances having a term of up to one year and no prepayment penalties. As of the date of the release of the Audited Consolidated Financial Statements, the Corporation has not accessed the BTFP. </span></div><div style="margin-top:8pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Such reliance on secondary funding sources could increase the Corporation's overall cost of funding and thereby reduce net income. While the Corporation believes its current sources of liquidity are adequate to fund operations, there is no guarantee they will suffice to meet future liquidity demands. This may necessitate slowing or discontinuing loan growth, capital expenditures, or other investments, or liquidating assets.</span></div>
