The foundation or primary factor in determining the appropriate credit quality rating is the degree of a debtor’s willingness and ability to perform as agreed. In conjunction with evaluating the performing versus nonperforming nature of our loan portfolio, management evaluates the following credit risk and other relevant factors in determining the appropriate credit quality indicator (rating) for each loan portfolio: Pass Grade: no may ● Strong Cash Flows – borrower’s cash flows must meet or exceed our minimum debt service coverage ratio. ● Collateral Margin – generally, the borrower must have pledged an acceptable collateral class with an adequate collateral margin. ● Qualitative Factors – in addition to meeting our minimum cash flow and collateral requirements, a number of other qualitative factors are also factored into assigning a Pass Grade including the borrower’s level of leverage (debt to equity), prospects, history and experience in their industry, credit history, and any other relevant factors including a borrower’s character. Those borrowers who qualify for unsecured loans must fully demonstrate above average cash flows and strong secondary sources of repayment to mitigate the lack of unpledged collateral. Watch Grade: may one not ● The primary source of repayment may ● The primary source of repayment is adequate, but the secondary source of repayment is insufficient ● In-depth financial analysis would compare to the lower quartile in two ● Volatile or deteriorating collateral ● Management decisions may ● Delinquencies in bank credits or other financial/trade creditors ● Frequent overdrafts ● Significant change in management/ownership Special Mention Grade: may not not not ● Inadequate or incomplete loan documentation or perfection of collateral, or any other deviation from prudent lending practices ● Credit is structured in a manner in which the timing of the repayment source does not ● Current economic or market conditions exist which may ● Adverse trends in the borrower's operations or continued deterioration in the borrower’s financial condition that has not ● The borrower is less than cooperative or unable to produce current and adequate financial information Substandard Grade: not not may may not The following represents, but is not not ● Sustained or substantial deteriorating financial trends, ● Unresolved management problems, ● Collateral is insufficient to repay debt; collateral is not ● Improper perfection of lien position, which is not ● Unanticipated and severe decline in market values, ● High reliance on secondary source of repayment, ● Legal proceedings, such as bankruptcy or a divorce, which has substantially decreased the borrower’s capacity to repay the debt, ● Fraud committed by the borrower, ● IRS liens that take precedence, ● Forfeiture statutes for assets involved in criminal activities, ● Protracted repayment terms outside of policy that are for longer than the same type of credit in our portfolio, ● Any other relevant quantitative or qualitative factor that negatively affects the current net worth and paying capacity of the borrower or of the collateral pledged, if any.

Our ALLL methodology incorporates management’s current judgments, and reflects management’s estimate of future loan and lease losses and risks inherent in the loan portfolio in accordance with ASC Topic 450 Contingencies 310 Receivables The allowance is increased by provisions charged to expense and adjusted for charge-offs or recoveries. In periodic evaluations of the adequacy of the allowance may Management monitors delinquent loans continuously and identifies problem loans to be evaluated individually for impairment testing. For loans that are determined impaired, a formal impairment measurement is performed at least quarterly on a loan-by-loan basis. Our method for assessing the appropriateness of the allowance includes specific allowances for identified problem loans, an allowance factor for categories of credits and allowances for changing environmental factors (e.g., portfolio trends, concentration of credit, growth, economic factors). Allowances for identified problem loans are based on specific analysis of individual credits. Loss estimation factors for loan categories are based on analysis of local economic factors applicable to each loan category. Allowances for changing environmental factors are management’s best estimate of the probable impact these changes have had on the loan portfolio as a whole. We believe that the ALLL was adequate as of March 31, 2019. no not may As of March 31, 2019, 82% may may may Impaired loans are individually evaluated for impairment. If the measurement of each impaired loans’ value is less than the recorded investment in the loan, we recognize this impairment and adjust the carrying value of the loan to fair value through the ALLL. For collateral dependent loans, this can be accomplished by charging off the impaired portion of the loan based on the underlying value of the collateral. For non-collateral dependent loans, we establish a specific component within the ALLL based on the present value of the future cash flows.

We review and approve these policies and procedures annually. Monitoring and reporting systems supplement the review process with regular frequency as related to loan production, loan quality, concentrations of credit, potential problem loans, loan delinquencies, and nonperforming loans.The following is a brief summary, by loan type, of management’s evaluation of the general risk characteristics and underwriting standards: Commercial Loans may may Most commercial loans are generally secured by the assets being financed and other business assets such as accounts receivable or inventory. Management may may may Commercial Real Estate (“CRE”) Loans The properties securing the CRE portfolio are diverse in terms of type and primary source of repayment. This diversity helps reduce our exposure to adverse economic events that affect any single industry. We monitor and evaluate CRE loans based on occupancy status (investor versus owner occupied), collateral, geography, and risk grade criteria. Generally, CRE loans are made to developers and builders that are secured by non-owner occupied properties require the borrower to have had an existing relationship with the Company and a proven record of success. Construction loans are underwritten utilizing feasibility studies, sensitivity analysis of absorption and lease rates, and financial analysis of the developers and property owners.
