Any impaired loan for which a determination has been made that the economic value is permanently reduced is charged-off against the allowance for loan losses to reflect its current economic value in the period in which the determination has been made. At the time a collateral-dependent loan is initially determined to be impaired, we review the existing collateral appraisal. If the most recent appraisal is greater than a year old, a new appraisal is obtained on the underlying collateral. Appraisals are updated with a new independent appraisal at least annually and are formally reviewed by our internal appraisal department upon receipt of a new appraisal. All impaired loans and their related reserves are reviewed and updated each quarter.

Accordingly, all loan losses are charged to the related allowance and all recoveries are credited to it. Additions to the allowance for loan losses are provided by charges to income based on various factors that, in our judgment, deserve current recognition in estimating probable incurred credit losses. The Company reviews the loan portfolio on an ongoing basis and makes provisions for loan losses on a quarterly basis to maintain the allowance for loan losses in accordance with US GAAP. The allowance for loan losses consists of two • specific allowances established for any impaired residential non-owner occupied mortgage, multi-family mortgage, nonresidential real estate, construction and land, commercial, and commercial lease loans for which the recorded investment in the loan exceeds the measured value of the loan; and • general allowances for loan losses for each loan class based on historical loan loss experience; and adjustments to historical loss experience (general allowances), maintained to cover uncertainties that affect our estimate of probable incurred credit losses for each loan class. The adjustments to historical loss experience are based on our evaluation of several factors, including levels of, and trends in, past due and classified loans; levels of, and trends in, charge–offs and recoveries; trends in volume and terms of loans, including any credit concentrations in the loan portfolio; experience and ability of lending management and other relevant staff; and national and local economic trends and conditions. The Company evaluates the allowance for loan losses based upon the combined total of the specific and general components. Generally, when the loan portfolio increases, absent other factors, the allowance for loan loss methodology results in a higher dollar amount of estimated probable incurred credit losses than would be the case without the increase. Conversely, when the loan portfolio decreases, absent other factors, the allowance for loan loss methodology generally results in a lower dollar amount of estimated probable losses than would be the case without the decrease. The loss ratio used in computing the required general loan loss reserve allowance for a given class of loan consists of (i) the actual loss ratio (measured on a weighted, rolling twelve two Mortgage Servicing Rights Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type.

The majority of the loans the Company originates are commercial-related loans, such as multi-family, nonresidential real estate, commercial loans and leases, and construction and land loans. In addition, we originated one four December 31, 2017. The Company originates real estate loans principally secured by first Multi-family mortgage loans generally are secured by multi-family rental properties such as apartment buildings, including subsidized apartment units. In general, loan amounts range between $500,000 and $5.0 million at December 31, 2020 not 25% Loans secured by multi-family mortgages generally involve a greater degree of credit risk as a result of several factors, including the concentration of principal in a limited number of loans and borrowers, the effects of general economic conditions on income producing properties, and the increased difficulty of evaluating and monitoring these types of loans. Furthermore, the repayment of loans secured by multi-family mortgages typically depends upon the successful operation of the related real estate property. If the cash flow from the project is reduced below acceptable thresholds, the borrower’s ability to repay the loan may The Company emphasizes nonresidential real estate loans with initial principal balances between $500,000 and $5.0 million. Substantially all of our nonresidential real estate loans are secured by properties located in our primary market area. The Company’s nonresidential real estate loans are generally written as three five three five In the underwriting of nonresidential real estate loans, the Company generally lends up to 80% of the property’s appraised value. Decisions to lend are based on the economic viability of the property as the primary source of repayment and the creditworthiness of the borrower. In evaluating a proposed commercial real estate loan, we emphasize the ratio of the property’s projected net cash flow to the loan’s debt service requirement (generally requiring a minimum ratio of 120%), computed after deduction for a vacancy factor and property expenses we deem appropriate. Personal guarantees are usually pursued and obtained from nonresidential real estate borrowers. Nonresidential real estate loans generally carry higher interest rates and have shorter terms and typically involve larger loan balances concentrated with single borrowers or groups of related borrowers. In addition, the payment of loans secured by income-producing properties typically depends on the successful operation of the related real estate project and thus may The Company makes various types of secured and unsecured commercial loans to customers in our market area for the purpose of financing equipment acquisition, expansion, working capital and other general business purposes. The terms of these loans generally range from less than one five Commercial credit decisions are based upon our assessment of the borrower’s cash flow, proposed collateral, business and credit history and any additional positive or negative credit risk factors. The Company determines the borrower’s ability to repay in accordance with the proposed terms of the loans and we assess the risks involved. An evaluation is made of the borrower to determine character and capacity to manage. Personal guarantees of the principals are pursued and usually obtained. In addition to evaluating the loan borrower’s financial statements, we consider the adequacy of the primary and secondary sources of repayment for the loan. Independent reports of the borrower’s credit history supplement our analysis of the borrower’s creditworthiness and at times are supplemented with inquiries to other banks and trade investigations. Moreover, certain assets listed on personal financial statements are verified. Proposed collateral for a secured transaction also is analyzed to determine its marketability. Commercial business loans generally have higher interest rates because they have a higher risk of default since their repayment generally depends on the successful operation of the borrower’s business and the sufficiency of any collateral. Pricing of commercial loans is based primarily on the credit risk of the borrower, with due consideration given to borrowers with appropriate deposit relationships. The Company also lends money to small and mid-size leasing companies for equipment financing leases. Generally, commercial leases are secured by an assignment by the leasing company of the lease payments and by a secured interest in the equipment being leased. In most cases, the lessee acknowledges our security interest in the leased equipment and agrees to send lease payments directly to us. Consequently, the Company underwrites lease loans by examining the creditworthiness of the lessee rather than the lessor. Lease loans generally are non-recourse to the leasing company. Generally, the Company’s commercial leases are secured primarily by technology equipment, medical equipment, material handling equipment and other capital equipment. Lessees tend to be publicly-traded companies with investment-grade rated debt or companies that have not not five Although the Company does not Until December 31, 2017, four first The ability of the Company’s borrowers to repay their loans, and the value of the collateral securing such loans, could be adversely impacted by economic weakness in its local markets as a result of unemployment, declining real estate values, or increased residential, office, industrial and retail shopping vacancies due to changes in business conditions.

Any impaired loan for which a determination has been made that the economic value is permanently reduced is charged-off against the allowance for loan losses to reflect its current economic value in the period in which the determination has been made. At the time a collateral-dependent loan is initially determined to be impaired, we review the existing collateral appraisal. If the most recent appraisal is greater than a year old, a new appraisal is obtained on the underlying collateral. Appraisals are updated with a new independent appraisal at least annually and are formally reviewed by our internal appraisal department upon receipt of a new appraisal. All impaired loans and their related reserves are reviewed and updated each quarter.

Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Loan Losses: may may The Company provides for loan losses based on the allowance method. Accordingly, all loan losses are charged to the related allowance and all recoveries are credited to it. Additions to the allowance for loan losses are provided by charges to income based on various factors that, in our judgment, deserve current recognition in estimating probable incurred credit losses. The Company reviews the loan portfolio on an ongoing basis and makes provisions for loan losses on a quarterly basis to maintain the allowance for loan losses in accordance with US GAAP. The allowance for loan losses consists of two • specific allowances established for any impaired residential non-owner occupied mortgage, multi-family mortgage, nonresidential real estate, construction and land, commercial, and commercial lease loans for which the recorded investment in the loan exceeds the measured value of the loan; and • general allowances for loan losses for each loan class based on historical loan loss experience; and adjustments to historical loss experience (general allowances), maintained to cover uncertainties that affect our estimate of probable incurred credit losses for each loan class. The adjustments to historical loss experience are based on our evaluation of several factors, including levels of, and trends in, past due and classified loans; levels of, and trends in, charge–offs and recoveries; trends in volume and terms of loans, including any credit concentrations in the loan portfolio; experience and ability of lending management and other relevant staff; and national and local economic trends and conditions. The Company evaluates the allowance for loan losses based upon the combined total of the specific and general components. Generally, when the loan portfolio increases, absent other factors, the allowance for loan loss methodology results in a higher dollar amount of estimated probable incurred credit losses than would be the case without the increase. Conversely, when the loan portfolio decreases, absent other factors, the allowance for loan loss methodology generally results in a lower dollar amount of estimated probable losses than would be the case without the decrease. The loss ratio used in computing the required general loan loss reserve allowance for a given class of loan consists of (i) the actual loss ratio (measured on a weighted, rolling twelve two
